Abstract The phase composition of Co-30Cr-6Al-0.5Y coating deposited by plan-ar magnetron sputtering as well as the effect of sputtering parameters on it havebeen investigated. The sputtered coating is composed of hcp ε-phase or fcc α-phaseof Co solid solution with a minority β-CoAl intermetallic phase. The hcp ε-Cophase and the fcc α-Co phase assumed a <100> and <110> preferred orientationrespectively. Both phase type and orientation extent depend on the sputtering para-meters. If the substrate surface is paralleled to the target face during sputtering, thecoating will be of fine crystal with compact structure and smooth surface; if it isrotated, the coating will be to the contrary.
