It is well known that residual stresses in a ground material can be seen as a complex superposition of compressive stress introduced by the mechanical loading and tensile stress introduced by the subsequent quenching. As the formation of cracks in a coating, the phase XL019 in the substrate near the interface of coated samples promotes some changes in the equilibrium state of stresses. In the case of chromium coating on a steel substrate, the combined effects of heat conduction leading to phase transformation in the substrate, cracking and mechanical loading of the coating is not yet clearly elucidated. Further research is required to determine the exact role of ion different effects on the residual stress state after grinding.
A more precise evaluation of the grinding effect will therefore be obtained on the basis of the residual stress and crystallographic texture analysis within samples Gw and Ad.
According to our observation and results, a chromium burned surface can be adequately described by a layer with high stress and texture gradients and to a highly deformed material induced by mechanical shearing of the heated surface.
