A process in which cubic zirconia forms on a metal surface accompanied by an infusion of zirconium metal into the treated metal carbide at relatively low temperatures has reportedly been developed by C3 Corp., Alpharetta, Ga. The coaling has been applied to cutting tool inserts, increasing life by as much as 400% for milling aluminum, while raising tool speed.

The zirconia adheres directly to the material treated, without the need for intermediate bond layers. It is applied at a temperature of 450[degrees]C (840[degrees]F), by dipping the part into the solution and ...
