{"title":"Nano-Scratch and Micro-Scratch Properties of CrN/DLC and DLC-W Coatings","authors":"Funsho Olaitan Kolawole, Marcos Dantas dos Santos, Shola Kolade Kolawole, Paulo Konrad Vencovsky, Danilo Assad Ludewigs, André Paulo Tschiptschin","doi":"10.1520/mpc20230028","DOIUrl":"https://doi.org/10.1520/mpc20230028","url":null,"abstract":"Diamond-like carbon (DLC) coatings are well known for their excellent adhesion to silicon wafers. However, they often exhibit poor adhesion properties on metallic substrates. Interlayers and metallic doping help improve the adhesion properties of DLC coatings on metallic substrates. In this study, both nano-scratch and micro-scratch were performed on chromium nitride (CrN)/DLC and tungsten doped DLC coating (DLC-W) coatings deposited on 920 HV DIN 16CrMn martensitic valve tappets. Nano-scratch was performed at 300 mN in a Hysitron nano-indenter, whereas micro-scratch was performed at 1–50 N using a CETR-UMT tribometer. The 3-D images and 2-D longitudinal and transversal profiles of the nano-scratch and micro-scratch were obtained using atomic force microscopy and 3-D optical profilometry, respectively. The scratch hardness equation was used to estimate the scratch hardness of the coatings. Experimental and theoretical values for the volume removed and the specific wear rates for the micro-scratch and nano-scratch of CrN/DLC and DLC-W coatings were estimated. The coefficients of friction (COF) obtained during the micro-scratch tests were very similar for both coatings. The same happened with the COF measured during the nano-scratch. The maximum COF in both cases reached 0.14. The wider and deeper penetration of the indenter for the DLC-W coating was mainly due to the lower hardness of the multilayered coating, composed of alternating nanometric thick amorphous carbon and tungsten carbide (WC) layers. The greater wear observed for the DLC-W coating system could also be attributed to the abrasive effect of detached WC nanoparticles abrasively acting during the contact of the diamond tip with the DLC coating. The experimental and theoretical values for the volume removed and the specific wear rates indicate a lower volume removal and specific wear rate for CrN/DLC because of higher hardness and better load-carrying capacity, contrary to DLC-W, which presents higher volume removal and specific wear rate because of its lower hardness.","PeriodicalId":18234,"journal":{"name":"Materials Performance and Characterization","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135304040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The microstructure morphology is examined using x-ray diffraction and scanning electron microscopy with energy-dispersive x-ray spectroscopy. The microstructure reveals that there would be a strong correlation between phase structure and sustainability for localized corrosion behavior. The lowest crystallite size of the magnesium-based HEA powder mixture suggests the highest corrosion resistance because of the solid-solution face-centered cubic and body-centered cubic phases for 20 h of milling. The correlation between the microstructural morphology and functional properties such as hardness, corrosion resistance, and potentiodynamic parameters are compared for both magnesium-based and non-magnesium-based HEAs and analyzed to elucidate their suitability for lightweight vehicle applications.","PeriodicalId":18234,"journal":{"name":"Materials Performance and Characterization","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different processes can produce it with the desirable microstructures and mechanical properties. This study presents an original method, flux-core-double-wire of gas-shielded tungsten arc welding, in which wires of different compositions are used simultaneously to obtain different microstructures. The deposition was controlled through the following parameters: welding speed, deposition current, standoff distance, torch angle, and pulse frequency of wire feed. Four coatings were deposited on AISI 1020 steel substrate by combining the cored wires: Fe–Cr–C, Fe–Cr–C–Nb, Fe–Cr–C–Mo–Nb, and Fe–Cr–C–Mo–Ti. The combination of these wires resulted in a hypoeutectic microstructure with niobium and titanium carbides, with an average hardness of 650 HV0.3. The hypereutectic microstructures were formed by different niobium contents, with a microhardness range from 820 to 1,020 HV0.3. The performance of the hardfacing was evaluated in the rubber wheel abrasion test described by ASTM G65, Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus (Superseded), procedure B. The results revealed that the carbide cracking distinguished the wear resistance, and the hardness was not enough to separate the wear behavior. Still, the volume fraction of carbides was a decisive microstructural parameter.","PeriodicalId":18234,"journal":{"name":"Materials Performance and Characterization","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135352951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A detailed study was conducted on the relationship between the volume fraction of ferrite, cementite, austenite, and residual cementite during the phase transformation process and the changes in heating temperature and heating rate. An austenizing model for the transformation of pearlite to austenite during homogenization heat treatment was proposed. The interfacial concentration, phase equilibrium, free energy of transformation, and eutectoid temperature between austenite and pearlite were calculated by Thermo-Calc software. The experimental phenomenon of the transition from pearlite to austenite during homogenizing heat treatment was theoretically explained.","PeriodicalId":18234,"journal":{"name":"Materials Performance and Characterization","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135352800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
