Abstract: A method of making a diamond coated insert (310) includes, obtaining a substrate (204) of durable and diamond adherent material having a substantially smooth surface on which is coated a diamond layer (222) using any known CVD technique, and partitioning the diamond covered substrate (204) with a laser beam into multiple inserts (310) with desired geometries. If desired, the insert edges (318a-c) and corners (320a-c) may be thereafter machined or ablated until the desired smoothness and finish are achieved, and a fastening throughbore (324) may be preformed or drilled in the center of each insert (310). The diamond coated inserts (310) as formed have a top surface entirely coated by a surface layer (222) of diamond of a first thickness, and at least one rake face (208) which is not diamond coated beyond the surface layer (222) of diamond.

Abstract: A mandrel for use in a diamond deposition process has surfaces with different diamond adhesion properties. According to one embodiment, a mandrel is provided and has first and second surfaces on which a diamond film is deposited, with the second surface forming a perimeter around the first surface. The first surface of the mandrel has a first diamond bonding strength which is less than a second diamond bonding strength of the second surface. In an embodiment for forming a cup-shaped diamond film, the mandrel is a titanium nitride (TiN) coated molybdenum (Mo) substrate having a stepped solid cylindrical shape with a central mesa having a side wall or flank. The side wall is etched near the top surface of the mesa to expose a molybdenum band and to form a second surface which bounds the TiN first surface. When the molybdenum band loses efficiency as a result of diamond particles remaining in the molybdenum band after a diamond deposition procedure, a second strip of the TiN coating adjacent to the first strip may be etched or machined to expose a second band of molybdenum. Other embodiments of the invention include machining the molybdenum band on the mesa top surface, machining a stepped molybdenum band, using a separate and detachable molybdenum foil or wire applied to grooves in the mandrel, and forming radial lines or patches on the surface of the mandrel.
