Correlation of acoustic, physicochemical, and mechanical properties of coatings obtained using electron-beam welding deposition of chromium carbide on low-carbon steel
Tóm tắt
Multifunctional coatings have been developed using the method of nonvacuum electron-beam welding deposition of chromium carbide powder on low-carbon steel. The correlation dependences of the ultrasonic velocity, the thickness of coatings, the content of chromium in the coatings, and the loss of mass under exposure to corrosive media on the mechanical properties are constructed using the bend tests. It was shown that the observed correlation relations are mainly determined by two factors, i.e., the presence of a substitute doping agent of chromium in a solid solution and the character of a dislocation structure, which forms inside of the grain.
