A study on adhesion property of evaporated Al-Cr films was conducted on steel sheet by using two-source evaporator. Adhesion of Al-Cr coated steel was evaluated by tape test after $180^{circ}$bending. Adhesion was decreased with increasing the Cr content in Al-Cr films. It was thought that the decrease in adhesion with increasing Cr content be related to insufficient wetting and diffusion of Cr atoms in the film. Best adhesion was achieved in the case of pure aluminum film..
