Abstract

Experimental Analysis and Effect of Coating on HSS Cutting Tool

Highlights

Titanium nitride(TiN) structured is a golden yellow refractory compound of low density (5.22 g/cm3) and high melting point (2930°C) the another coating material which is used for this experimental study is Aluminum chromium nitride (AlCrN) of having Bluish grey in color
In this paper we have studied three tools in which two tools are coated with Titanium Nitride (TiN), Aluminium chromium nitride (AlCrN) and one tool is uncoated and its comparative points of tip point wear rate, rise in chip-tool interface temperature is calculated and measured by calculations and observations
It is found that the rise in temperature, wear rate of uncoated tool is more as compare to coated tools when it is working on lathe machine for turning operation the performance of coated tool is more as compare to uncoated tool

Summary

Introduction

Titanium nitride(TiN) structured is a golden yellow refractory compound of low density (5.22 g/cm3) and high melting point (2930°C) the another coating material which is used for this experimental study is Aluminum chromium nitride (AlCrN) of having Bluish grey in color. Titanium nitride as a coating for tool steels has been available widely since the last decade and is enjoying increasing attention and application in tool industries. The reasons are simple yet important the advantages of TiN, AlCrN coatings of tool steels include a noble appearance, excellent adhesion to substrates, high chemical inertness, resistance to elevated temperatures, a low coefficient of friction with most work piece materials which increases lubricity, results in excellent surface finish, decrease of horsepower requirements, improved ability to hold tolerances, high temperature stability, low maintenance cost and high productivity.
