Article reviews three regimes of spraying, with a focus on the wear behaviour under the different conditions. RocDur 37 was selected as feedstock material. Regimes applying different feed were used: 1.43 cm/s (A), 1.85 cm/s (B), 0.88 cm/s (C); rotation speed - 1.33 s−1. Wear was tested on the contactsliding, edge-wear and abrasive-wear machines. Regimes B and C showed lower wear in contact-sliding and edge-wear. Hydro-abrasive test showed similar wear of coatings obtained using all parameters, it can be concluded that RocDur 37 coatings are suitable for work in abrasive conditions. In this type of wear technological parameters do not affect wear. The optimum technological regimes: rotation speed 1.33 s−1, longitudinal feed 0.88 cm/s, and 11 passes.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"262"},"PeriodicalIF":0.8,"publicationDate":"2017-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43205194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have been classified by microstructure at room temperature. Two stainless steel grades 304 and 410L were studied in this paper. Hot rolling was performed on a Hille 100 experimental rolling mill under various reductions with consideration of the oxide scale thickness controlled by oxidation time. The experimental results show that the deformation behaviour of the oxide scale on the stainless steel 304 is sensitive to its thickness and exhibits higher resistance to be deformed. However, the reduction in thickness plays an important role in the uniformity of the oxide scale deformation for the stainless steel 410L. Friction coefficients were calculated and compared. Simulations results show that the reduction in thickness and initial surface roughness play roles on final surface roughness. Steel substrate surface is rougher than that of the oxide scale at different reductions.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"241"},"PeriodicalIF":0.8,"publicationDate":"2017-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJSURFSE.2017.085623","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45393039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coarser grains in the base material re-orient to fine dendrites during laser surface melting. The equiaxed grains are refined with increased laser power and reduced interaction time under the influence of higher cooling rate. The finely refined grains improve the microhardness of the treated surface. The tribological performance and its mechanism of the treated surfaces were evaluated at room temperature and at 500°C.

To get insight on seeds early growth and evaluate the seeding efficiency of different suspensions, silicon samples were exposed to diamond growth conditions before seeding; this leaves a thin carbon film on the substrate surface. Following this step samples were seeded with commercial nanodiamond suspensions, exposed again to growth conditions and characterised by SEM. Results showed that seeding suspensions played a role depending on particle size and nature of dispersing medium. Seeding density was larger and more uniform in samples pre-exposed to diamond growth conditions. The carbon film deposited during the pre-treatment improves deagglomeration of nanodiamond seeds via a more effective interaction between substrate surface and seeds. This procedure represents a viable way to grow thin conformal diamond coatings by HFCVD.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"225-240"},"PeriodicalIF":0.8,"publicationDate":"2017-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJSURFSE.2017.085622","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46602548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most of previously published works regarding textured bearings neglected the cavitation effect and make their results questionable. The main aim of this paper is to investigate the hydrodynamic performance of slip pocketed bearings considering cavitation by a theoretical approach. Cavitation was of particular interest with respect to pressure generation and shear stress. One main result presented here was that slip over the whole surface could retard the presence of cavitation and therefore the generated pressure and shear stress could be optimal. The work presented here leads to a design reference guideline that could be used by the designer/engineer to design slip pocketed bearings for improving the hydrodynamic performance.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"100-117"},"PeriodicalIF":0.8,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJSURFSE.2017.084669","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44011303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, erosion of the blade material is tested under simulated conditions of the real blade. Abrasive particles impingement angles of 90° and 54° are tested to predict the erosion characteristics on the blade. The predicted blade erosion is validated using the data taken from on-site blades. The eroded specimens are examined by scanning electron microscopy, and wavelength- and energy-dispersive X-ray spectroscopy. According to the observations, although the 90° impingements make more pits than 54° impingements, the latter creates longer and more critical pits than the former. Furthermore, the results show that the erosion in the on-site blades is strong enough to assist the formation of severe pits on them which eliminates the crack initiation time.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"85"},"PeriodicalIF":0.8,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45163480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By varying the applied load on the groove-textured surfaces in the direction perpendicular to grooves, the positive curvature shows a decrease in static contact angle initially then increases for further increase in deflection; however, the negative curvature induced by the same applied load shows an opposite trend. At the same time, in the pillar-textured surface, the static contact angle decreases with increase in applied load for the positive curvature and the same wetting parameter shows an opposite trend for the negative curvature. This phenomenon is mainly attributed to the pinning behaviour of the three phase contact line of the liquid drop on these two surfaces.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"174"},"PeriodicalIF":0.8,"publicationDate":"2017-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46306890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
