Method of removing diamond coating and method of manufacturing diamond-coated body

摘要

A method of removing a diamond coating from a substrate of a diamond-coated body which includes the substrate coated with the diamond coating. The method includes a step of heating the diamond-coated body at a predetermined temperature in a reactor at a predetermined reduced pressure, while introducing an oxygen gas into the reactor at a predetermined flow rate, for burning the diamond coating to thereby remove the diamond coating from the substrate.
