Abstract

A Cu-36at.%In-15at.%Ga coating layer is manufactured using a warm spray process and ternary alloy powders. The powder used had a particle-size distribution of 5∼22μ with a spherical shape and average particle size of 11.6μ. Pure aluminum plate was used as a substrate. As a result, a CIG coating layer with 120μ thickness was successfully obtained. In order to improve the density of the coating layer, post heat treatment was applied for 1 hour in each condition of 200, 300 and 400°C. Phase analysis of the powder initially used identified Cu₉In₄, Cu₉Ga₄ phases, and Cu₉In₄, Cu₉Ga₄, Cu₃Ga phases were identified after warm spraying. As heat treatment was applied, porosity decreased from 0.98% (as sprayed) to 0.8% (400°C), showing an increase in density, and hardness also decreased from 304Hv (as sprayed) to 258Hv (400°C).
