Laser Cladding of Stainless Steel with Hastelloy

Funded under: FP5

Abstract

The feasibility of applying a Hastelloy coating to a stainless steel surface by melting a Hastelloy wire on the the substrate surface using a CO2 laser has been investigated. Single and multiple coatings have been produced. They exhibit excellent bonding to the substrate. The microstructure of the coating has been examined applying light optical microscopy, scanning electron microscopy and transmission electron microscopy. Due to convection in the molten pool some substrate material has mixed with the Hastelloy in the coating. The composition of a multiple layer shows enrichment in iron and depletion in nickel as compared to the composition of Hastelloy. The hardness of the layer is typical of a Hastelloy quenched after solution heat treatment.
