Wear Performance of Ti Based Powders Coating on SS 304 by PVD Method

The PVD techniques range over a wide variety of applications from decorative, to high temperature superconducting films. The thickness of the deposits can vary from angstroms to millimeters. A very large number of inorganic materials—metals, alloys, compounds, and mixtures—as well as some organic materials can be deposited using Physical vapour Deposition (PVD) technologies. Traditionally, the term hard coatings refer to the property of high hardness in the mechanical sense with good tribological properties. The analysis of PVD coating on stainless steel has been carried out. The objectives of the coating are to check the properties and wear performance of coated and uncoated materials. For this project, we selected stainless steel discs as a substrate; among those three of them are coated with Ti based powder deposited by using PVD method. While after the coating process has been completed the roughness of each coated and uncoated material has been carried out. Ensure that the weight of the materials should be checked before the wear test is to be performed. Now the wear performance of the coated and uncoated materials should be carried out, in order to achieve the low co-efficient of friction in coated materials than the uncoated materials by using Pin-On-Disc apparatus having Tribological Data Acquisition System. Again the weight of the materials should be checked to determine the weight loss of each material.
