Formation of Ti-Al-N dispersed composite layer on steel by TIG torch surface cladding

In this study an attempt has been made to produce titanium-aluminium dispersed hard nitride layer on mild steel surfaces by preplacement of 50% Ti and 50% Al powder mixture and then melting with TIG torch under nitrogen environment. Parameter such as heat input of the torch was varied between 540, 6...
