Abstract
Aluminide coatings are widely used to protect a vast variety of metals and alloys for high temperature applications. Under certain environments, these are not only designed to improve high temperature corrosion, but also eros ion. Therefore, the mechanical properties (such as toughness) of these prot ective coatings obtained by CVD-FBR are of prime importance taking into acc ount the advantages of this coating technique. In this paper, preliminary s tudies of mechanical characterisation of aluminide coatings obtained on AIS I 304 stainless steel by CVD-FBR deposited at 525 degreesC and different pr ocessing times are presented. The effect of a subsequent thermal treatment of the aluminide coatings has also been investigated. From the results, the relationship between coating process, heat treatment, and toughness is est ablished. (C) 2000 Elsevier Science B.V. All rights reserved.
