Paper Abstract

During direct laser cladding process teh substrate preheating temperature is selected together with interaction parameters of the 1.2 kW cw CO2 laser source. The Co-based protective coatings are prepared on chromium steel. A decrease of cracking susceptibility with increasing substrate temperature follows from the model calculation of the temperature and stress fields and is confirmed in experiment. For laser intensities around 108 W/m2 and preheating above 600°C the crack-free 2-layer coatings are produced.
