Abstract

This paper describes a new method to prepare NiAl intermetallic compound coating on carbon steel. In this study, NiAl intermetallic compound was firstly obtained by thermal explosion. Subsequently a NiAl coating was prepared on carbon steel by thermal plasma cladding. The results showed that, the final coating layer of single phase NiAl was obtained, the layer had dense micro structure, NiAl layer and carbon steel had high quality metallurgical bond..

Keywords
