The modified iron oxide particles were synthesized using the annealing method and the evaluation of the corrosion-resistant benefits of modified iron oxides as additive in the epoxy resin coating was conducted. The raw FeOOH phase can be transformed into the α-Fe2O3 phase by increasing the annealing temperature. The morphology, colors, and pore size of the modified iron oxide are controllably evolved via finely adjusting the annealing temperature, which is beneficial for the compatibility, dispersion, and stability with epoxy resin. Besides, modified α-Fe2O3 annealed at 700 °C exhibited elliptical morphology and good solubility in epoxy resin solvents to form a hydrophobic corrosion inhibition layer (TP700), which further improves the corrosion resistance. Findings of corrosion electrochemical measurements and salt spray test confirmed the existence of TP700 composite coating resulted in the best corrosion protective properties on aluminum alloy during the corrosion process with the minimum corrosion current of 7.75 × 10−10 A cm−2 and the maximum |Z|0.01Hz value of 1.80 × 108 Ω cm2, which both are about two orders of magnitude higher than the commercial Fe2O3.

Two adhesives using MWCNTs and NPs of SiC in selected amounts were developed using Polyaryletherketone (PAEK) thermoplastic polymer as a base matrix. Fabricated joints using these adhesives were characterized for degglomeration and dispersion of NPs, lap shear strength (LSS), and failure modes. Based on the data on the LSS, the advantages and disadvantages of using individual NPs were analyzed, and the third adhesive was designed in a sandwich manner, where positive points of both the NPs were expected to work synergistically. The sandwich adhesive showed higher LSS than the individual ones, i.e., an 8.6% and 26% improvement to SiC-based and MWCNT-based adhesives, respectively. It was concluded that the strengthening mechanism of MWCNTs of bulk polymer in the central portion was beneficial. The two outer layers of SiC NPs in PAEK interacting with the two steel surfaces of coupons proved helpful in increasing friction and, hence, synergistically increasing the LSS of sandwich adhesive.","PeriodicalId":22028,"journal":{"name":"Surface Topography: Metrology and Properties","volume":"100 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140617280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aims to combine surface engineering and welding engineering to produce a niobium-rich coating using submerged arc welding (SAW) deposition. SAW is a cost-effective technique that allows high deposition rates and technical simplicity, which can enhance mechanical properties and resistance to abrasive wear of components. This research involves the addition of a FeNbC powder alloy in percentages of 5, 10, and 15 wt% to a neutral commercial SAW flux, as an alternative to adding Nb to the microstructure of the deposited coating. The coating was characterized by optical microscopy to analyze the microstructure, such as the presence of phases; microhardness through a Vickers micro-durometer, and resistance to abrasive wear through the loss of mass using a rubber wheel-type abrasometer. The wear mechanisms were evaluated using scanning electron microscopy. The results showed that a Nb-rich coating can be deposited via SAW, and the coatings successfully increased microhardness by up to 110% and resistance to abrasive wear to values higher than the base metal used (microalloyed steel). The microstructure formed was rich in Fe2Nb and NbC, proving the formation of Nb-rich phases. Additionally, the mechanism of abrasive wear was predominantly plastic for the base metal and changed to micro-cutting and micro-plowing after the addition of up to 15% of FeNbC.","PeriodicalId":22028,"journal":{"name":"Surface Topography: Metrology and Properties","volume":"48 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140313000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For prosthesis applications, the corrosion resistance of metals is one of the major prerequisites to avoid impairment of the material properties due to degradation. The combined action of corrosion and wear on the material is called tribocorrosion and DLC (Diamond-Like Carbon) films have been extensively studied to increase prosthesis biocompatibility and to protect from corrosion. Additionally, DLC coatings can prevent the prosthesis to release toxic elements due to plastic deformation and corrosion. This paper is about tribocorrosion studies on DLC and DLC-Ag (DLC containing silver nanoparticles) on Ti-6Al-4V substrates. These films were obtained by PECVD (Plasma Enhanced Chemical Vapor Deposition) using hexane as a precursor. The tribocorrosion behavior of uncoated and coated samples was investigated in the reciprocating mode in Ringer’s lactate solution. From the polarization test results, the protective efficiency of the film was calculated. Silver nanoparticles improved the corrosion resistance of the films. The protective efficiency was 15 and 19% for DLC and DLC-Ag films, respectively.","PeriodicalId":22028,"journal":{"name":"Surface Topography: Metrology and Properties","volume":"144 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140312643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the surface quality of the regenerator plays a crucial role in the heat transfer effect and service life of magnetocaloric systems during wire electrical discharge machining (WEDM) when fabricating rare-earth Gd array microstructure regenerators. In this study, different process parameters were used to conduct a process experiment of the WEDM of rare-earth Gd. First, the evolution of the surface microstructure and its causes were analyzed using a single-factor experiment, while a corrosion test was conducted on the samples. The analysis showed that the pulse-on time and open voltage considerably affected the surface quality of the processed samples, while the samples with better surfaces exhibited good corrosion resistance. Additionally, a Taguchi experiment was designed, and a regression analysis used to establish regression models between the process parameters (pulse-on time, pulse-off time, peak current, open voltage, and water pressure) and both surface roughness (SR) and material removal rate (MRR). The results showed that the average prediction errors of SR and MRR were only 5.34% and 5.48%, respectively.","PeriodicalId":22028,"journal":{"name":"Surface Topography: Metrology and Properties","volume":"34 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140312790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This procedure was tested on synthesised fractal and multifractal Brownian surfaces. The use of the method of detrended fluctuation analysis to determine the Hurst index for samples with a size not exceeding 2000 points was analysed. The optimal values of the sample size and the scale parameter have been obtained, allowing the Hurst index to be calculated with an error of less than 20%. The procedure was also tested on greyscale images, which are 8-bit representations of a synthesised fractal surface. The peculiarities of the application of the procedure for calculating the local fractal dimension for images obtained by scanning electron microscopy have been analysed. The values of the local fractal dimension of the oxide support MgAl2O4 are calculated using SEM images at different magnifications. It has been shown that, taking into account the fractal dimensionality calculation, different morphologies of the particle surface are observed at different scales of image magnification. At the highest magnification, the particle surface is found to consist of embedded smooth micron particles.

One parameter to quantify this is the <italic toggle=\"yes\">small-scale fidelity limit T</italic>\u0000FIL defined in ISO 25 178-600:2019. To determine this parameter, sinusoidal structures are generated, where the wavelengths are modulated according to a discrete chirp series. The objects are produced by means of ultra-precision diamond face turning. Planar areas and regions with slopes below 4° could be produced with form deviations of ≲10 nm. An initial estimate of the cutting tool’s nose radius resulted in a deviation that caused the ridges of the structures to be too narrow by approximately 150 nm, while the trenches were too wide. At the bottom of narrow trenches, deviations are observed in the form of elevations with heights of about 20 to 100 nm. The measurement standard investigated in this study has also been used to characterise optical instruments in a round-robin test within the European project TracOptic, which requires precise knowledge of the geometry of all structures.

The analysis included the evaluation of the topography, roughness, mechanical properties, and tribological performance of the texturized surfaces. Both manufacturing routes were suitable for fabricating deterministic surfaces, being the micro CNC method the one that provided better repeatability and surface finishing as well as higher hardness. These factors influenced the tribological behavior of the polyamide when in contact with AISI 304 stainless steel.
