  • the plated layer is provided on the surface of the metal head, it is possible to provide a property of the plating material constituting the plated layer in the head or the surface thereof as it is. Accordingly, for example, when the material having a specific gravity greater than that of the material for the head is plated on the surface of the metal head, it is possible to efficiently increase a moment of inertia and expand a sweet spot. Further, when the hardness of the surface of the head is made harder by the plating material, it is easy to obtain an optimum spinning amount necessary for improving a flying distance of the ball and it is also possible to improve a batting feeling.
  • a titanium alloy, an aluminum alloy or a stainless alloy is used for the material of the metal head, however, as mentioned above, the titanium alloy has been mainly used in the recent days.
  • the specific gravity of the titanium material is about 4.5
  • the specific gravity of the aluminum material is about 2.7
  • the specific gravity of the chrome material is about 7.2
  • the specific gravity of the nickel material is about 8.8.
  • Fig. 1 shows an outer appearance of a head for a golf club in accordance with the present embodiment
  • the head for the golf club is a hollow metal head (a metal wood head) 1 formed by a titanium alloy, and is structured such that a plating layer 3 shown in Fig. 2 is provided on all over the outer surface including a face 2 of the metal head 1 and the plating layer 3 is constituted by a nickel plated layer 4 excellent in an adhesion property and a bonding property against a titanium corresponding to a subject to be plated.

  • the blasting treatment is performed in order to increase the adhesion property of the plated layer by roughing the surface of the head, and the alkaline degreasing treatment is performed in order to remove stains attached to the surface of the head.
  • a nickel sulfamate is plated on the surface of the head as the ground plating. This is performed in order to stabilize the plated layer by plating the nickel sulfamate having a low stress.
  • a bright nickel is plated as an intermediate layer. This is performed in order to increase a uniform electrodeposition property of the next chrome plating by plating the bright nickel as the intermediate nickel. The chrome is then plated on the outermost layer.
  • the copper is plated in place of the bright nickel in the procedure mentioned above.
  • the adhesion property of the plated layer is further improved.
  • the adhesion property of the plated layer is further improved because the copper plating is excellent in an impact resistance, to thereby has an effect of preventing a peeling. This is caused by a property of the copper plating, that is, a flexibility of the copper plating is high and a stress of the copper plating is less than that of the nickel plating.
  • the copper layer, the nickel layer and the chrome layer are provided on the metal head made of the soft iron alloy from the side of the internal layer, a copper strike plating, a copper plating, a bright nickel plating and a chrome plating are applied after applying the alkaline degreasing treatment onto the surface of the metal head.
  • the stress in electrodeposits comprises a tensile stress and a compressive stress.

  • the present invention can obtain the following effects.
  • the surface of the head can have the feature corresponding to the property of the plating material constituting the plated layer.
  • the hardness of the surface of the head can be increased by providing the plated layer made of the material having a hardness greater than that of the material for the head on the surface of the head. Accordingly, a flying distance of the ball which has never been experienced can be achieved, an initial velocity of the ball can be increased, and a spin amount of the ball can be decreased. Further, because a good batting sound is generated, it is possible to achieve a batting feeling good for the player.
  • a water deflection on the surface of the face is improved so as to restrict the spin amount, so that it is possible to prevent a drop ball readily generated when it rains from generating.
