[0025] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are specifically cited below and described in detail with reference to the accompanying drawings; in addition, the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0026] Please refer to Figure 1 , Figure 2 As shown, it is a preferred embodiment of the golf club head with surface coating of the present invention, comprising a club head body 1 and a surface coating 2, wherein the surface coating 2 is located on at least a portion of the surface of the club head body 1.

[0027] The club head body 1 can be in the form of a swing head or a putter head. The club head body 1 can be made of materials such as stainless steel, carbon steel or titanium alloy, so that the club head body 1 has sufficient structural strength and the surface of the club head body 1 has sufficient corrosion resistance. When the surface coating 2 is covered on the surface of the club head body 1 by chemical deposition or electroplating, the structure of the club head body 1 will not be damaged by corrosion, which facilitates subsequent processing.

[0028] The surface coating 2 may be located on at least a portion of the surface of the club head body 1, or the surface coating 2 may cover the entire club head body 1, so that the appearance and color of the club head body 1 can be uniform, which has the effect of further beautifying the appearance of the club head body 1. The surface coating 2 may be formed on the surface of the club head body 1 by existing physical vapor deposition (PVD) methods such as sputtering or evaporation. For example, the club head body 1 may be formed on a 3×10 -3 ~12×10 -3 Under a vacuum degree of 1.5 Pa, acetylene is introduced as a working gas and reacts with a predetermined metal plating material at 25-80° C. In this way, the surface coating 2 can cover the entire surface of the club head body 1 or a portion of the surface of the club head body 1 according to the requirements of the finished product. The thickness of the surface coating 2 can be 1.9-2.7 μm to avoid poor coverage due to the surface coating 2 being too thin, and to avoid stress concentration caused by the surface coating 2 being too thick, which easily causes cracks on the surface of the club head body 1.

[0029] In detail, the surface coating 2 has a base layer 21, which is bonded to the surface of the club head body 1. The base layer 21 can be a metal coating containing chromium (Cr) or titanium (Ti). Preferably, the base layer 21 is a chromium carbide layer (CrC) or a titanium carbide layer (TiC). In this embodiment, the thickness of the base layer 21 can be 0.1-0.2 μm, so that the base layer 21 can be tightly bonded to the club head body 1. In addition, the base layer 21 can fill the holes or fine lines on the surface of the club head body 1, so that the club head body 1 can form a smooth surface effect.

[0030] The surface coating 2 has a buffer layer 22, which can be electroplated on the base layer 21. The buffer layer 22 can be a titanium tungsten carbide layer (WTiC), so that the buffer layer 22 has better toughness. In this embodiment, the thickness of the buffer layer 22 can be 0.8-1 μm. Since the buffer layer 22 is a titanium tungsten carbide layer, the surface coating 2 can have good toughness, so that the surface coating 2 can have better impact resistance and is not easily cracked by impact.

[0031] The surface coating 2 has a coloring layer 23, which can be electroplated on the buffer layer 22. The coloring layer 23 is used to make the surface coating 2 form a dark color, for example, a predetermined dark color can be presented by different metal plating materials. In this embodiment, the coloring layer 23 can be a tungsten carbide layer (WC), so that the coloring layer 23 can present a black color with a metallic luster. In this embodiment, the thickness of the coloring layer 23 can be 1 to 1.5 μm, and the color of the club head body 1 can be further deepened by the coloring layer 23 to form a deeper color and a metallic luster appearance. It is worth noting that, taking the tungsten carbide layer as an example, the tungsten carbide layer has high hardness, but low tolerance to impact. Therefore, the surface coating 2 can improve toughness by including the buffer layer 22, and deepen the presentation of black by the tungsten carbide of the coloring layer 23.

[0032] In order to prove that the surface coating 2 can deepen the color of the surface of the club head body 1, the L value (brightness) in the Lab color space is used to evaluate the color depth of the club head body 1. It can be measured that the L value of the club head body 1 is 29-32, that is, it can present a better color depth. In addition, the wear resistance of the club head body 1 with the surface coating 2 is measured to be as high as 10,000 times. In addition, the club head body 1 is subjected to an angle adjustment test. When the tube handle of the club head body 1 is bent by -1 to 3 degrees, no cracks or wrinkles are observed on the surface coating 2, which also shows that the surface coating 2 has good strength.

[0033] In summary, the golf club head with surface coating of the present invention can further make the surface of the club head body reach a predetermined L value by having the surface coating on the surface of the club head body, so as to deepen the color of the appearance of the semi-finished club head, thereby improving the quality of the finished product. In addition, the surface coating makes the club head body have good wear resistance, thereby improving the durability of use.

[0034] Although the present invention has been disclosed using the above-mentioned preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications to the above-mentioned embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the technical scope protected by the present invention. Therefore, the protection scope of the present invention shall include all changes within the meaning and equivalent scope of the appended claims.
