Study of Thermomechanical Properties of Multilayer Nanocomposite Film Systems

─The paper presents modeling and research of the state of thermal and deformation fields for a plate made of AISI/SAE 1045 steel without coating, with a single-layer coating of TiN, with a double-layer coating of TiCN/a-Al

The processes of heat transfer and the peculiarities of the formation of strain-stress fields in the cutting tool depending on the structural composition and the state of multilayer film coatings were investigated. The effect of a nano-sized multilayer film system of different composition on the spread of thermal and strain-stress fields in the cutting zone under the influence of thermal load was investigated.
