Abstract

This study investigated the effects of carrier gases (He and N2) on the microstructure and properties of Ti coating layers to manufacture high-density Ti layers using the cold spraying. Cold spray coating layers manufactured using He had denser and more homogenous microstructures than those produced using N2. Layers manufactured using He gas showed porosity of 0.02% and hardness of 229HV, which are better properties than the porosity (0.4%) and hardness (177HV) of N2 coating layers. The bond strength of coating layers manufactured using He recorded higher value of 74.28MPa than that manufactured using N2. This could be attributed to the fact that, when coating layers are manufactured using He gas, the powder can be easily deposited because of its high particle impact energy, facilitating the plastic deformation of the particles.
