The Increasing of the Operational Stability of Wood-Working tools by the laser cementation

摘要： The paper describes the technology of laser cementation of woodworking tools, which allows to increase the operational stability no less than twice. The tool wear resistance is increased due to carbon saturation of the surface to 1.8-2.0% and the formation of martensite and residual austenite on the surface of the structural composition. The tests results of wear resistance and determination of the period of resistance of the treated tool are given. The modes of laser cementation for the studied grades of tool steels are offered.
