[ What is claimed is:] [1.] A method of manufacturing a metal part coated with a layer of polycrystalline diamond, said method comprising:depositing a layer of carbon having at least 10% graphitic plus amorphous carbon onto a surface of a metal substrate, said metal substrate surface comprising at least one of titanium and its alloys; anddepositing a polycrystalline diamond coating on said carbon layer, said layer of carbon diffusing fully through the titanium during said depositing of said polycrystalline diamond, wherein said depositing the polycrystalline diamond coating is carried out at temperature in the range of 400-700.degree. C. from an activated gaseous mixture at a pressure of approximately 10 Torr, said activated gaseous mixture including an oxygen containing compound.
