Abstract
The purpose of present study was to examine the erosion wear behaviour of Fe-Cr coating deposited on 316 L steel using HVOF coating technology. Chromium content was varied (0-15) wt. % in the step of 5 wt. %. The erosion wear test was performed on Air Jet Erosion Tester by choosing set of parameters as per steady state condition and Taguchi Orthogonal array L16. On adding 5 wt. % Cr, the mechanical properties such as hardness and fracture toughness were improved by 21% and 47% respectively. In steady-state wear conditions, specific wear rate was increased with the increase in impact velocity and slurry concentration. Taguchi design of experiment revealed a particular set of parameter for minimum erosion wear rate such as chromium content of 15 wt. %, impact velocity of 40 m/sec, impingement angle of 45° and slurry concentration of 8 gm/litre.
期刊介绍：
IJSurfSE publishes refereed quality papers in the broad field of surface science and engineering including tribology, but with a special emphasis on the research and development in friction, wear, coatings and surface modification processes such as surface treatment, cladding, machining, polishing and grinding, across multiple scales from nanoscopic to macroscopic dimensions. High-integrity and high-performance surfaces of components have become a central research area in the professional community whose aim is to develop highly reliable ultra-precision devices.
