The structural changes in the coatings after post-treatment were assessed by X-ray diffraction analysis and Raman spectroscopy. Microhardness was improved for cryogenically treated coatings due to the α-Co transformation into ϵ-Co. Cryogenic treatment duration was not having a significant effect on the microhardness values. However, the specific wear rate was influenced by the cryogenic treatment duration. Also, corrosion resistance was increased with the increased cryogenic treatment duration. The protective layers consisting of WO3 and Co3O4 phases formed during the cryogenic treatment are attributed to the improved corrosion resistance of the coatings.","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"326 - 338"},"PeriodicalIF":2.8,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44572004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 consequences of the thermal cycle might be detrimental to the material’s fatigue resistance depending strongly on the resulting microstructure. The 4340 steel is known to present temper embrittlement, which greatly reduces its fatigue life and weldability. This work proposes plasma nitriding as an alternative solution to tempering as a post-weld treatment and investigates its effects on material’s hardness and fatigue life. This analysis was complemented by microstructural and fracture surface characterization. Plasma nitriding resulted in the formation of a double layer consisting of a smaller white micrometric nitride layer at the surface and a more diffuse sub-superficial region which led to better fatigue behaviour when compared with the conventional tempering treatment. The achieved higher surface hardness might also be interesting in other applications such as those involving high erosion and wear.","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"339 - 348"},"PeriodicalIF":2.8,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46754100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reaction conditions, such as the dip-coating solution concentration, the thermal curing reduction temperature, and the reaction time were demonstrated to be key factors in forming hierarchical DTMS-rGO nanocomposites, which significantly affected the surface wettability of the PU sponge. The resulting DTMS-rGO-PU sponge with a static water contact angle (WCA) of 152.2° displayed superior superhydrophobicity, and achieved an oil–water separation efficiency of 99.89% for various oil/water mixtures. This superhydrophobic sponge also showed minimal deterioration in its high oil adsorption capacity after 100 recycled adsorption operations. Furthermore, the as-prepared DTMS-rGO-PU sponge was proven to be physically and chemically stable and durable in harsh environmental conditions, suggesting its potential for industrial applications in oil spillage management.","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"349 - 360"},"PeriodicalIF":2.8,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45173495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The properties of the coatings were analysed by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electrochemical workstation. The comprehensive analysis demonstrates that adding proper amount of Sc(NO3)3 increased the oxidation voltage, which transformed the worm shape discharge micropores into round-hole shape, and the MAO coatings presented a double-layer structure. The primary phase composition of the coatings was γ-Al2O3, α-Al2O3, Sc2O3 and Al3Sc. The optimum concentration of Sc(NO3)3 was 0.6 g L−1. The hardness reached a maximum value of (1284 ± 43.5) HV, which was about 2.5 times higher than that without adding. The self-corrosion current density reduced from 138.00 × 10− 7 A cm−2 (substrate) to 3.65 ×  10− 7 A cm−2, which was approximately two orders of magnitude lower, indicating that the corrosion resistance was improved.","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"307 - 314"},"PeriodicalIF":2.8,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43012926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sudarshan","doi":"10.1080/02670844.2023.2225004","DOIUrl":"https://doi.org/10.1080/02670844.2023.2225004","url":null,"abstract":"Surfaces define the outer boundaries of an object and interact with the surrounding medium in a multitude of ways. Surface texture, defined as “the local deviation of a surface from a perfectly flat plane “[1], is a crucial determinant of the functionalities of various materials, be they natural or man-made. In nature, surface texture has evolved to meet the diverse survival needs of living organisms. For instance, Darkling beetles Figure 1(a) and some types of cacti Figure 1(b) that inhabit desert environments possess specialised bumps, grooves, or 3D hierarchical structures on their body surfaces, which condense water from the air [2,3]. The surface texture of the lotus leaf Figure 1(c) is the most cited example of hydrophobic surfaces, bordering on being a cliché. Manmade surface textures can be perceived as nominal or actual. The nominal surface refers to the intended contour of the surface, while the actual surface is determined by the manufacturing processes used to create it [5]. Surface texture is typically categorised into roughness, waviness, lay, and flaws Figure 2. Roughness is determined by the characteristics of the materials and processes used to form the surface and manifests as small, finely-spaced deviations from the nominal surface. Waviness, on the other hand, consists of much larger deviations caused by factors such as work deflexion, vibration, and heat treatment. Roughness is typically superimposed on waviness. The lay of the surface texture refers to the predominant direction or pattern of the surface, while flaws are irregularities that occur occasionally on the surface, such as cracks, scratches, and inclusions. Although flaws are related to surface texture, they also affect surface integrity. The texture of a surface can contribute to aesthetics, safety, assembly, and functionality. For example, the shininess or dullness of a surface can impact its perceived aesthetic value, while the surface’s mechanical properties, absorption, friction and wear, corrosion and wear behaviour, adhesion, and electrical and thermal conductivity, can affect its overall functionality. Smooth surfaces are better suited for electrical contacts, while rough surfaces are better suited for water repellency and friction like in brakes. The texture is the single driving cause for the presence or absence of friction between mating surfaces. As early as the 18th century, Bernard Forest de Bélidor recognised that friction arises from the numerous hemispherical peaks and valleys on the mating surfaces, a concept furthered by Coulomb in his exposition of lubrication [8]. There are various categories of texturing methods, including addition, removal, displacement of material, and self-forming methods [9]. The most common industrial texturing processes such as shot blasting, milling, grinding, etching, lithography, laser methods, and manual polishing fall under the removal category.
