Abstract

An approach for fabricating specimens with composite coatings of Co60 and TiCN (titanium carbonitride) via selective laser cladding (SLD) is presented. The focus aims at adding (0%wt., 10%wt., 20%wt., 30%wt., 40%wt., and 50%wt.)TiCN at gradual mass fraction in Co60 powder as mixed cladding composite material. The laser cladding specimens are examined for microstructure, composition, microhardness and resistance to corrosion. Experimental results indicate that Co60+(30%wt.)TiCN laser cladding layer has remarkable resistance to corrosion, attributing to dendrite microstructure, Co60 as binder phase and ceramic particles TiCN and its decomposition products as strengthening phase dispersed in the cladding layer.
