Impact of Cladding Technology on Residual Stresses within the Renovation of High Pressure Die Casting Molds

Abstract

Residual stresses significantly affect the overall lifetime of constructions. The main disadvantage of residual stresses is that their effect and magnitude is not evident at first sight and can only be reliably determined using experimental methods. The experiment aimed to find out how much the cladding technology affects the residual stresses within the renovation of high pressure die casting molds. A total of four samples were prepared by different cladding techniques and with varying thicknesses of the result layer. The samples were then annealed and mechanically treated. Finally, the hole drilling method was applied to determine the residual stresses in the samples. The results point to more significant differences in the levels of residual stresses, which were determined in the subsurface layers.
