Abstract
A diamond covered member which has a diamond crystal layer is formed by vapor phase synthesis on a surface of a substrate. The process comprises depositing plate-shaped diamond crystals by CVD at a carbon source concentration ranging from 0.01 to 10% at an atomic ratio of oxygen to carbon (O/C) of 0.5.ltoreq.(O/C).ltoreq.1.2 in a starting gas. The crystals may also be deposited by a burning flame method using an oxygen-acetylene flame at a molar ratio of oxygen to acetylene in a main starting gas in the range of 0.9.ltoreq.(O.sub.2 /C.sub.2 H.sub.2).ltoreq.1.0. The plate-shaped diamond crystals are grown to coalesce into a film to form the diamond crystal layer.
