Abstract: Cutting operation is very essential aspect in manufacturing scenario. Application of coating on tool surface helps to improve tribological properties of surface such as wear and coefficient of friction of the surface. Cutting life time of a tool material is significantly affected by wear. The performance of various coatings on tool material is inspected by studying the variation of its two properties viz. wear & coefficient of friction. These essential tribological properties have been evaluated by using pin on disc test. This paper is focused on various low friction coatings such as TiN, CrN and DLC coating on High speed steel T-42 pin as a base material. This paper deals with the study of performance parameters like speed, sliding distance and load compared between different coated HSS-T42 pin base materials. Taguchi method is used under the performance parameter & L9 orthogonal array is selected to perform experiment on pin on disc of the specimen. The EN31 steel material is selected as work piece material. The response value found out by using coefficient of friction which was obtained from pin on disc test. Scanning Electron Microscopy (SEM) analysis for compared different coated pin for micro structural test.
Keywords: HSS T-42 pin, Wear, Coefficient of Friction, TiN, CrN, DLC.
