摘要
Refurbishment of damaged components is nowadays a useful solution to save maintenance costs. Laser cladding is one of the most advantageous solutions to fulfill this kind of repair. With the aim of reusing deteriorated steam circuit parts of thermal power stations, a laser cladding process has been developed. Different Co-based alloys of Stellite (R) and Tribaloy (R) families, which offer good resistance against impact, corrosion and erosive wear at high temperatures, were used as coating materials to improve the durability of this repair. A comparative study of morphology, structure and hardness of the deposited layers with optimized parameters has been carried out. (C) 2011 Published by Elsevier B.V.
