“…Within the nanoscaled form, amine functionalised-Sm2O3 nanobelts exhibit an improve of the electrochemical and optical properties of conducting and non-conducting polymers such as polypyrrole and poly(ethylene oxide) [9]. Zang et al [10] reported on the use of nano-sized particles of Sm2O3 to improve on the microhardness as well as the wear and corrosion resistance properties of Nickel-based alloys coatings. Numerous accounts of the role of Sm 3+ in heteregenous catalysis, phosphors for luminescent devices, medical diagnostics and therapeutic ends have been reported [11][12][13].…”

Abstract:The aim of this study was to develop a composite coating on 304 stainless steel employing a TIG (tungsten inert gas) process. Ti wire cored with graphite powder was used as the means of coating material. The process parameters were controlled to develop a coating with optimum characteristics (i.e., hardness and wear resistance). The microstructure of the coating was analyzed with SEM and XRD. It was found that both the hardness and the wear resistance increase as the current increases, while both of these properties decrease as travelling speed increases. It was found that the coated samples with composite layers were harder than the substrate and can range up to 1100 HV, almost 4.5 times higher than the hardness of 304 stainless steel. Likewise, the wear resistance of the coating was observed to be 4.5 times higher than that of the substrate. The high performance of the coating, as revealed by microstructural analysis, was due to the formation of TiC and Cr 23 C 6 . The optimum conditions for producing the coating are thus proposed to include a 120 A current and a 3.17 mm/s travel speed.

Abstract:The aim of this paper is to develop a composite coating on St 304 steel employing TIG process. Ti wire cored with graphite powder is used as the means of coating material. The process parameters are varied in order to develop coating with optimum characteristics (i.e., hardness and wear resistance). The microstructure of the coating is analyzed with SEM and XRD. It is found that both of the hardness and wear resistance increase as the current increases while both of these properties decrease as the travelling speed increases. It is found that the coated samples with composite layers have more hardness than the substrate and it could range up to 1100 HV being almost 4.5 times higher than the hardness of St 304. Likewise, the wear resistance of coating is observed to be 4.5 times higher than that of substrate. The high performance of coating, as revealed by microstructural analysis, is due to formation of TiC and Cr23C6 .The optimum conditions to produce the coating are proposed to be 120 A current and 3.17 mm/s travel speed.
