Article Preview

In this work, tungsten inert gas cladding (TIG), is utilized to in-situ synthesize the (Ti,W)C based cermet cladding layers. The microstructure and microhardness of the cladding layers were analyzed by scanning electron microscopy (SEM) and microhardness tester. The grain abrasion resistance of the cladding layers is also discussed. The grain abrasion resistance of the coating is also discussed. The results showed that excellent bonding between the coating and the AISI 1045 steel substrate was uniform, continuous and almost defect-free. (Ti,W)C cladding layers have compact microstructure and high microhardness. The grain abrasion resistance of the coating is attributed by the compact microstructure.
