Optimization of Operating Parameters on Wear Behavior of Manganese Phosphate Coated Die Steel

Abstract:

The aim of Manganese Phosphate coating is to convert the metallic surface completely into a non metallic surface. A Phosphating is a chemical conversion treatment which produces a porous surface layer of crystalline phosphate. High carbon high chromium steels are commonly used in applications requiring excellent wear resistance in tool and die making industries. The wear characteristic of the coated steel was evaluated through pin on disc test as per ASTM G99 standards using a sliding velocity of 3.0m/s under constant loads. Taguchi’s design of L₀₉ orthogonal array is followed selecting three parameters namely load, surface roughness, sliding distance. Optimal conditions are arrived by Signal-Noise ratio method with respect to coefficient of friction. The results are validated by analysis of variance (ANOVA) and the percentage of contribution of load, surface roughness and sliding distance for better coefficient of friction are determined.
