ABSTRACT:
A coated steel product, namely, a cutting instrument such as a band saw blade, in which the body of the blade is of steel, the tooth tip is of impulse hardened steel and the tip is covered with a coating of titanium carbide or refractory metal carbide, the coating metal or compound having been deposited by ion plating onto the surface of the tip. The process through which the cutting tool is produced includes preshaping and sharpening the tool, then ion cleaning the tips, bombarding the tips with ions of the titanium or refractory metal followed by reacting the titanium or refractory metal with a carbon containing chemical or their carbides and then simultaneously subjecting both the coating and the steel tip to a magnetic flux for impulse hardening primarily the steel tip. Other coatings of metal carbides, nitrides, borides and metal compounds are described.
