Formation of Ti-Al-N dispersed layer on steel surface by TIG melting in a reactive environment

Formation of Ti-Al-N dispersed layer on steel surface by TIG melting in a reactive environment

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...
