Abstract

PURPOSE:To work tightly metallized diamond parts at low temperatures by roughening the surface of the diamond parts by oxygen ion impact and then by sticking a metallic layer to the roughened surface by vacuum deposition, etc. CONSTITUTION:To metallize diamond parts tightly, a work process including oxygen ion impact is effective. Namely, a holder 22 mounting the diamond parts 23 in a vacuum container 20 is applied with a 1,000V negative high voltage with a switch 25 placed at a side 1, and oxygen gas is introduced into the container 20 to about 5X10<-2> Torr; and glow discharged between the parts 23 and a main electrode 21 is caused and oxygen ions generated as a result of the discharge strike the surface of the diamond parts 23, etching the surface layer by 0.05mum. Then, the switch 25 is changed over to a side 2 to apply the negative high voltage to the main electrode 21, and argon is used as discharge gas. Then, a conductive film material 24, e.g., Hf is evaporated by sputtering to stick to the surface of the etched diamond parts to 0.1mum thickness.
