がある。2. Description of the Related Art As a performance of a golf club, it is desired to have a greater flight distance and excellent directional stability. Conventionally, the flight distance is increased by increasing the strength of the constituent material of a golf club head (hereinafter referred to as a head), but on the other hand, it is said that directional stability is lacking. On the other hand, if the head is made of a softer material, there are drawbacks that the flight distance is not long and the head is easily scratched. Therefore, various materials such as iron, aluminum, carbon, titanium, etc. have been proposed and implemented as constituent materials (materials) of the head, but improvement in flight distance and directional stability can be achieved only by improving the head material. There is a limit to the improvement of.

匠性を有し得る。As described above, the golf club shaft according to the present invention is a golf club shaft in which the golf club shaft base material is made of a carbon material, and the P content on the surface of the base material is 0.1 wt%. Since it has the above Ni-P type plating coating layer, it has excellent flight distance and directional stability due to this base material like the conventional carbon shaft, and the Ni-P type plating coating layer on the surface of this base material. Due to the above, it can have excellent wear resistance, scratch resistance and designability as compared with the conventional carbon shaft.

発明に係るシャフトは、従来のカーボンシャフトと同様
に飛距離及び方向安定性に優れている。That is, since the shaft base material is made of a carbon-based material, mechanical and physical properties similar to those of the carbon-based material constituting the conventional carbon shaft (strength, toughness, rigidity, vibration characteristics, etc. required for the shaft). Therefore, the shaft according to the present invention is as excellent in flight distance and directional stability as the conventional carbon shaft.

調をユニークな色調に改善することもできる。On the other hand, the Ni-P-based plating coating layer on the surface of the base material is significantly harder than the carbon-based material of the base material and is excellent in wear resistance and scratch resistance, and is the base material (base material). Since the adhesion to the carbon-based material is also good, the shaft according to the present invention can have excellent wear resistance and scratch resistance as compared with the conventional carbon shaft. In addition, the Ni-P-based plating layer originally has excellent surface quality, and has a gloss and an aesthetic appearance such as a champagne gold color, so the color tone of the shaft is bright and the designability (aesthetic appearance) is improved. Further, metallic luster can be imparted, and the dark color tone of the carbon shaft can be improved to a unique color tone.

慮すると25wt% 以下にすることが好ましい。Here, the P content in the Ni-P system plating coating layer must be 0.1 wt% or more as described above. This is because if the P content is less than 0.1 wt%, the hardness of the plating layer is low, the wear resistance and scratch resistance are reduced, and the gloss is also poor, resulting in insufficient required performance. still,
The P content may be 0.1 wt% or more, and the upper limit of the P content is not specified. However, if it exceeds 30 wt%, the wear resistance is slightly decreased due to the decrease in the toughness of the Ni-P-based plating coating layer. Since it occurs and the adhesiveness to the base material is slightly lowered, it is desirable to set it to 30 wt% or less, and more preferably 25 wt% or less in consideration of the plating efficiency.

It is preferably formed by electroplating. That is, the Ni-P-based plating coating layer can be obtained by electroless plating or electroplating, but the latter electroplating is preferably applied. This is because electroplating can control the plating film thickness and plating components more easily and cheaply. In this case, P content: within the range of 0.1 wt% or more, Ni-P
By adjusting the P content in the system coating layer, it is possible to control the hardness of the coating layer, thereby providing optimum plating quality according to each shaft.

Further, the thickness of the Ni-P based plating layer is not limited, and can be adjusted to an appropriate thickness as necessary. Further, the coating area of the Ni-P-based plating layer on the surface of the base material is not limited, and may be appropriately adjusted as necessary. For example, one portion is provided on an appropriate portion of the base material surface from the viewpoint of design surface. Alternatively, it may be coated at a plurality of locations, or may be coated on the entire surface.
