Summary:The appearance of residual stresses in metals is one of the effects accompanying the action of high-energy treatment. Under both electrospark and laser treatments, temperature is a prevailing factor affecting the formation of residual stresses. High rates of heating and cooling of a metal in the melting zone result in the appearance of thermal stresses determined by the difference between the coefficients of thermal expansion of the metal. A combined electrospark and laser treatment creates a stressed state in the surface layer with better characteristics than each treatment does separately. The value, sign, and distribution of the residual stresses substantially influence the service properties of machine parts.
