摘要
In order to study the shot peening that occurs during the application of powder coatings, experiments are carried out on glass shot peening of steel test strips using a CCDS2000 detonation device. Experimental dependences of the shot peening depth delta and the residual stresses sigma in a hardened layer on treatment parameters (particle size, density, and velocity, as well as the strength of the test strip material) are obtained. Engineering equations are proposed for calculating the values of delta and sigma.
