MICROWAVE PLASMA SINTERING

摘要

A method for producing an article having a composite surface including abrasive particles, comprises pressing a mixture of abrasive particles and a metal binding matrix to form a body, loading said body into a microwave plasma chamber, at least partially evacuating said chamber, and sintering the body in a microwave plasma for a period of time to produce said article. The method optionally includes a further method step, in which after the evacuation of the chamber a reducing or an inert gas (e.g. hydrogen) is introduced into said chamber.
