Incorporation of tic particulates on AISI 4340 low alloy steel surfaces via tungsten inert gas arc melting

Surface cladding utilizes a high energy input to deposit a layer on substrate surfaces providing protection against wear and corrosion. In this work, TiC particulates were incorporated by melting single tracks in powder preplaced onto AISI 4340 low alloy steel surfaces using a Tungsten Inert Gas...

Incorporation of tic particulates on AISI 4340 low alloy steel surfaces via tungsten inert gas arc melting
description Surface cladding utilizes a high energy input to deposit a layer on substrate surfaces providing protection against wear and corrosion.
