Abstract
A golf club head includes a rust-resistant coating layer forming on a base surface of at least one club head component of the golf club head. The rust-resistant coating layer is made from a Fe—Co—Ni alloy including iron of 5-20 wt %, cobalt of 5-25 wt % and nickel of 60-90 wt %, which is a nanometer-scaled material. The rust-resistant coating layer isolates the base surface of the club head component of the golf club head such that oxygen in the atmosphere cannot oxidize the base surface of the base surface of the club head component of the golf club head. Thereby, the rust-resistant coating layer carries out an increase of the antirust ability and hardness of the club head component of the golf club head.
