Abstract

A method of ductile mode machining a component of a plasma processing apparatus wherein the component is made of nonmetallic hard and brittle material wherein the method comprises single point turning the component with a diamond cutting tool causing a portion of the nonmetallic hard and brittle material to undergo a high pressure phase transformation to form a ductile phase portion of the hard and brittle material during chip formation wherein a turned surface is formed from a phase changed material and the turned surface is a grooved textured surface of phase changed material.
