The Effect of Cobalt on Wear behavior of Cemented Carbide cutting tools for machining of Titanium alloy

Abstract

Attempt has made to study wear behaviour of carbide cutting tools by varying cobalt content for machining of titanium alloys. Cobalt is used since it acts as a binder in matrix of cutting tool. The present study is more focused on the varying cobalt content and investigating tool life. The varied cobalt content samples were produced through powder metallurgy process using powder particle of average size 100-150 nm. Turning experiments were conducted to evaluate the effects of cobalt content on tool life. Results of turning experiments shows clearly that wear rate increases with increase in cobalt content of cutting tool at all cutting speeds.
