“…In the working process slotting tool is incured a thermal wear, formed as a result of friction of the backside of the teeth of cutting tool to the surface of the workpiece. The samples of EP657 material were coated intermetallic coatings of the Ti-Al system by developed technology [4]. Samples in the vacuum chamber are located as well as in parallel and perpendicular, to determine the difference of the thickness on vertical and horizontal surfaces.…”

“…It follows that to increase the resistance to elastic deformation, the material must have a high hardness with a low modulus of elasticity. Earlier, the authors [2,4] developed a new method for obtaining coatings based on the intermetallic compound of the Ti-Al system, which based on the synchronous deposition of Ti and Al from two electric arc evaporator, by heating substrate to a temperature of 700 K. As a results of conducted researches, has been established, that with the increase the substance intermetallic phases in the coating, mechanical properties are increase.…”
