The paper shows that gas-thermal coatings on the product surface may be considered on a first approximation as bimetallic material. Such approach permits to make calculations and determine residual stresses on the basis of multi-layer plate theory, mechanics of continuous medium and thermoelasticity.ΠΠΎΠΊΠ°Π·Π°Π½ΠΎ, ΡΡΠΎ Π³Π°Π·ΠΎΡΠ΅ΡΠΌΠΈΡΠ΅ΡΠΊΠΈΠ΅ ΠΏΠΎΠΊΡΡΡΠΈΡ Π½Π° ΠΏΠΎΠ²Π΅ΡΡ

Control over Coating Structure during Electromagnetic Welding and Application of HighSpeed Steel Powder
The paper considers peculiar features concerning coating formation in the process of electromagnetic welding of high-speed steel powder. The paper reveals how to control coating structure that ensures the required operational properties of working surfaces of machine parts
Elastic and Plastic Bar Bending and Residual Stresses
The paper proposes methodology for bar calculation in the case of elastic and plastic non-flat bending. It is shown how to determine an ultimate bending moment with single and two axes of symmetry in cross-section, residual stresses in case of unloading
Pattern of Residual Stress Formation at Gas-Thermal Coating Deposition
The paper shows that gas-thermal coatings on the product surface may be considered on a first approximation as bimetallic material. Such approach permits to make calculations and determine residual stresses on the basis of multi-layer plate theory, mechanics of continuous medium and thermoelasticity
