Cemented Tungsten Carbide-Based Material and Method for Making the Same

摘要

A cemented tungsten carbide-based material includes: a cemented tungsten carbide substrate having a chromized layer that contains a tungsten carbide and a chromium carbide; and a diamond film formed on said chromized layer. A method for making the cemented tungsten carbide-based material involves subjecting a cemented tungsten carbide substrate to chromization so as to form the cemented tungsten carbide substrate with a chromized layer that contains a tungsten carbide and a chromium carbide; and forming a diamond film on the chromized layer.
