Ni-based alloys, such as Inconel superalloys, are characterized by high strength, excellent fabricability (including joining), and outstanding corrosion resistance. However, their use is limited by their high cost. Ni-based coatings are used on carbon steel components in order to increase their service life under extreme conditions. Laser cladding deposition has emerged as an excellent method for processing Ni-based coatings. In this work, the evolution of the local wear behaviour of Inconel 625 laser cladded coatings after high temperature isothermal oxidation treatments have been investigated. ; The authors would like to thank the Spanish government CICYT through grants MAT2010-18916 and MAT2013-41784-R, the Universidad Rey Juan Carlos project URJC-CM-2010-CET-5550 and the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement number 605207 for financial support.
