Coated three faces Carbide Gear Cutter

According to the service environment and failure analysis of cemented carbide-coated inserts, when the hard coating is combined with a hard substrate (tungsten-titanium-cobalt carbide), under the action of impact load, due to the poor toughness of the substrate, the coating will be damaged. The cracks generated in the process are easy to expand into the matrix, causing the blade to be chipped and damaged and fail. When the hard coating is combined with a soft substrate (tungsten-cobalt-based cemented carbide), under the action of cutting force, due to the poor ability of the substrate to resist plastic deformation, the coating shell is prone to rupture, causing the coating to fail.
As the cemented carbide used in cutting tools, its representative materials are:

A. WC-Co type (tungsten cobalt type) cemented carbide;

B. WC-TiC(N)-Co type (tungsten titanium cobalt type) hard alloy Alloy;

C. Coated cemented carbide with hard film coated on the surface of the above two materials.
