Abrasion wear of HVOF sprayed coatings on SUS 400 stainless steel

摘要

This research diagnoses the optimization parameters for minimum mass loss of abrasive wear testing on SUS 400 stainless steel by design of experiment (DOE). In experimental, two input parameters that were the type of HVOF sprayed coating (i.e. CrC-NiCr and WC-12Co) and the testing distance (i.e. 3000m, 6000m, 9000m, 12000m, 15000m, 18000m, 21000m, 24000m, 27000m, and 30000m). Factorial experiment technique of DOE was used the MINITAB software for designing and analyzing of optimized parameters. The influences of two parameters on mass loss were investigated using analysis of variance (ANOVA) at 95% confidence level. The main effect and interaction of two parameters were significantly affect the mass loss. The statistical results of HVOF sprayed coating were indicated the WC-12Co better abrasive wear resistance than the CrC-NiCr.
