Trial on C3N4 Coating Cutter Hard-Dry Cutting on Hardened Steel
The method of “cutting instead of grinding” on hardened steel is always attractive to engineers. To gain this aim the tool material must first be found. C3N4 is a new kind of super hard material and has comparable properties with diamond in high hardness, wear-resistance, low friction coefficient and thermal conductivity. A number of dry-cutting tests were carried out by C3N4-film coated tool on hardened steel, proved the coating tool is suitable for hard dry cutting.
