PVD coated carbide grades Tungaloy consist of a cemented carbide substrate over which titanium compound such as TiN is covered to about 1 to 5 im thick by means of a physical vapor deposition PVD) method. Because of the lower coating temperature the substrate does not form any brittle harmful layer and can retain the original shape and dimension. The Ti(CNO) base coating is superior to TiN coating in wear resistance. And (TiAl)N base coating has higher resistance to oxidation. Due to the excellent toughness of both coating and substrate these grades are suitable for interrupted cutting. Their sharp cutting edge allows the grades to be used for cutting difficult-to-cut materials which tend to be work-hardened.
