ABSTRACT:
The presently claimed invention discloses a compound body of a wear resistant substrate with a surface coating, which body is suitable for wear parts and tools applications. The body includes top and bottom surfaces and at least one peripheral wall extending therebetween, the intersection of said peripheral wall and at least said top surface forming a cutting edge. The surface coating on said body is a diamond coating of a thickness of 1-30 .mu.m deposited directly from the gas phase in a reactor by CVD or PVD technique in a manner so as to ensure rigid bonding to said carbide substrate. The top face is provided with an integral chipformer so as to provide chips formed during machining into a desired and controllable configuration.
