change of твердосплавная plate резцедержателя токарного for processing railway wheel pairs

摘要

the utility model relates to the field of metal, namely, the режущему instrument for treatment of railway wheel sets.;proposed change of твердосплавная plate incisors токарного for processing railway wheel pairs is modeled on the basis of tungsten carbide and other carbides, as well as cobaltthe cutting edge has been нитридное coating layers, in which the first layer adjacent to the plate, is composed of нитрида titanium, second and third layer composed of nitride - titanium - алюмини ithe fourth layer is composed of the oxidized nitride - titanium - aluminium.;the technical result consists in improving the wear resistance and cutting efficiency of the tool.
