A Review of Various Low Friction Coating with HSS-T42 as Base Material

Cutting is very crucial aspect in a manufacturing situation & coating deposited on tool surface is to improving tribological properties of surface i.e. wear and coefficient of friction of the surface. Cutting life time of tool material depends on wear. In order to study the performance of various coating on tool material it is necessary to study its two properties viz. wear & coefficient of friction. The tribolgical properties are found by using pin on disc test. This paper focuses on various low friction coating such as TiN, CrN and DLC coating on High speed steel T-42 pin as a base material. The purposes to coating on tool surface in a cutting application are to increase cutting life time of tool, to improve the surface properties of component and to increase productivity. This paper deals with the study of performance parameters like speed, sliding distance and load compared between different coated HSS-T42 pin base material. Taguchi method are used under the performance parameter & L9 orthogonal array is selected to perform experiment on pin on disc of the specimen. The EN31steel material is selected as work piece material. The response value find out by using coefficient of friction which were obtained from pin on disc test. Scanning Electron Microscopy (SEM) analysis for compared different coated pin for microstructural test. This paper reviews different coating materials at different parameters & their effect on properties of metal.
