Diffusion saturation from fusible liquid metal media solutions by titanium of TK and WC-Co alloys as way to increase of tool durability

[摘要] The technology of applying titanium diffusion coatings on cutting tools of medium of fusible liquid-metal solutions has been describe. The results of research of process of heat treatment of carbide inserts of type WC-8%Co and TC after diffusion tianation from medium of fusible liquid-metal solutions has been describe. The results of influence of heat treatment of the cutting tool with diffusion titanium coating to its durability has been describe. It founded that the wear resistance of the tool and the microhardness of the coating influenced by the temperature of heat treatment and its duration, and the composition of the coated material. It is established that thermal treatment of carbide tools, the diffusion of titanium has a coating, allows to increase its durability in 1,5-2 times compared to the coated tool, but without heat treatment, relative to the tool without coating, durability is increased 7 times.
