Abstract
W pracy przedstawiono analizę stanu warstwy wierzchniej po laserowym stopowaniu stali Stellitem 6 oraz obróbce hybrydowej łączącej laserowe stopowaniem z obróbką nagniataniem. Obróbka hybrydowa prowadzona była na stanowisku laserowym. Do realizacji procesu nagniatania powierzchni wykorzystano głowicę do nagniatania ślizgowego umożliwiającą obróbkę w podwyższonych temperaturach jak i na zimno. Ocenę efektów obróbki hybrydowej przeprowadzono na podstawie badań chropowatości, mikrostruktury, mikrotwardości oraz badań naprężeń własnych.
Surface integrity after laser and laser-mechanical surface modification
Abstract
The results of experiments on the application of the new hybrid method, which combines the laser alloying process with slide burnishing, were presented. Both treatments were performed on the laser stage in one operation. The experiments were done on carbon steel alloyed with Stellite 6. The results of analysis of the surface roughness, microstructure, microhardness and residual stresses in surface layer after the laser alloying process and laser alloying combined with burnishing were presented.
