Abstract

The application of metal coating on cubic boron nitride (cBN) particles surfaces has emerged as an effective strategy for enhancing abrasive bonding performance, with thermal stability of these coatings recognized as a critical parameter in practical applications. This study investigates titanium–copper (Ti–Cu) coatings deposited onto cBN particle surfaces through vacuum vapor deposition techniques. Experimental findings demonstrate that Ti–Cu coatings exhibit significantly enhanced thermal stability at elevated temperatures (750°C) compared to conventional titanium coatings. This advancement stems from the synergistic integration of precise vacuum deposition process control with the inherent advantages of Ti–Cu composite materials, offering promising solutions for next-generation abrasive tools such as grinding wheels and cutting instruments.
