A nickel-phosphorus alloy or nickel boron alloy layer was coated on the surface of bat by and electroless plating method, so that the repelling power of the bat may increase, and abrasion of the bat decrease. The adhesion power of the alloy layer is 5-30kg/mm2 and proved to be 5-30 times together than alumite one. The alloy layer bat was hardened at 450≦̸C by thermal treatment.
