Abstract

The surface structure of a cutting insert of the standard (Ti,W)C–WC–6Co cemented carbide, T15K6, has been studied after interaction with a TiC–Ni based powder mixture. It has been shown that an external layer with two-phase (Ті,W)С–(Co,Ni) and intermediate (Ti,W)C–WC–6(Co,Ni) structures of variable composition is formed on the surface of this insert. The formation of the (Ti, W)С–(Co, Ni) structure in the external layer occurs as a result of Co, W, and C diffusion from the volume of an insert onto its surface and counter Ni diffusion from the surface of an insert into its volume.

与TiC-20Ni粉末混合物相互作用时，在79WC-15TiC-6Co硬质合金表面形成球形结构

摘要

在与TiC–Ni基粉末混合物相互作用后，已经研究了标准（Ti，W）C–WC–6Co硬质合金T15K6的切削刀片的表面结构。结果表明，在表面上形成了具有可变组成的两相（Ті，W）С–（Co，Ni）和中间（Ti，W）C–WC–6（Co，Ni）结构的外层这个插入物。外层中（Ti，W）С–（Co，Ni）结构的形成是由于Co，W和C从插入物的体积扩散到其表面上并抵消了Ni从金属表面的扩散所致。插入到其体积中。
