Description

Technical Field

[0001] The utility model relates to a golf club head, in particular to a golf club head with a surface coating. Background Art

[0002] When a golf club head requires a darker color, physical vapor deposition (PVD) is currently used. This involves sputtering or evaporating a suitable coating material onto the surface of the golf club head to achieve a better appearance. However, the color produced by conventional PVD methods is poor, making it difficult to meet product quality requirements.

[0003] In view of this, the existing coating still needs to be improved. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a golf club head with a surface coating, which can improve the color and quality of the club head.

[0005] The directions or their approximate terms described throughout the present invention, such as "front", "back", "left", "right", "upper (top)", "lower (bottom)", "inside", "outside", "side", etc., mainly refer to the directions of the accompanying drawings. Each direction or its approximate terms are only used to assist in explaining and understanding the various embodiments of the present invention and are not used to limit the present invention.

[0008] The golf club head with surface coating of the utility model comprises: a club head body; and a surface coating. The surface coating sequentially comprises a base layer, a strengthening layer and a coloring layer. The base layer is bonded to the surface of the club head body. The coloring layer is a titanium silicon carbide layer.

[0009] Therefore, the surface-coated golf club head of the present invention, by virtue of the surface coating on the club head body, can further enhance the surface of the club head body to a predetermined Lab value, thereby imparting a metallic luster to the semi-finished club head, thereby achieving a superior appearance. Furthermore, the surface coating imparts excellent wear resistance to the club head body, thereby enhancing durability.

[0010] The base layer is a metal plating layer containing chromium or titanium. Thus, the base layer can protect the club head body, and in particular, due to processing requirements, when the club head body is subjected to a stripping operation, the base layer can reduce the risk of damage to the club head body caused by the stripping operation.

[0011] The thickness of the base layer is 0.1-0.2 μm, thus filling the holes or fine lines on the surface of the club head body, making the club head body have a smooth surface.

[0012] The strengthening layer is a chromium carbide layer, so that the strengthening layer has good hardness.

[0013] The thickness of the strengthening layer is 1.4-1.6 μm, so that the surface coating can have better impact resistance and wear resistance.

[0014] The thickness of the coloring layer is 0.5-0.7 μm, so that the surface coating can form a high-brightness metallic luster appearance effect.

[0015] The color layer has an L value of 38 to 40, an a value of -4 to -5, and a b value of -9 to -11 in the Lab color space. This allows the surface of the club head body to achieve a predetermined Lab value, resulting in a better appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the above and other objects, 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, elements marked with the same symbols in different figures are regarded as the same and their descriptions are omitted.

[0025] Please refer to Figure 1 、 Figure 2 As shown in FIG. 1 , a preferred embodiment of a golf club head with a surface coating of the present invention is shown, which includes a club head body 1 and a surface coating 2 . The surface coating 2 is located on at least a portion of the surface of the club head body 1 .

[0026] 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.

[0027] The surface coating 2 can be located on at least a portion of the surface of the club head body 1, or the surface coating 2 can 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 can be formed on the surface of the club head body 1 by conventional physical vapor deposition (PVD) methods such as sputtering or evaporation. For example, the club head body 1 can be formed on a 5×10 -3 ~9×10 -3 Under a vacuum of 100 Pa, acetylene is introduced as a working gas to react with the predetermined metal plating material at a temperature of 25-150°C. The thickness of the surface coating 2 can be 1.5-2.5 μm to avoid poor coverage due to a thin surface coating 2 and cracking of the club head body 1 due to stress concentration caused by a thick surface coating 2.

[0028] Specifically, the surface coating 2 includes a base layer 21 bonded to the surface of the club head body 1. This base layer 21 can be a metal coating containing chromium (Cr) or titanium (Ti). Thus, the base layer 21 protects the club head body 1. In particular, due to processing requirements, when the club head body 1 is stripped, the base layer 21 can reduce the risk of damage to the club head body 1. In this embodiment, the base layer 21 can have a thickness of 0.1-0.2 μm, thereby ensuring a tight bond with the club head body 1. Furthermore, the base layer 21 can fill in any pits or fine lines on the surface of the club head body 1, resulting in a smooth surface.

[0029] The surface coating 2 includes a strengthening layer 22, which can be formed on the base layer 21. The strengthening layer 22 can be a chromium carbide layer (CrC). This provides the surface coating 2 with excellent hardness, thereby providing the surface coating 2 with better impact resistance and wear resistance. In this embodiment, the thickness of the strengthening layer 22 can be 1.4 to 1.6 μm. Furthermore, testing has shown that the strengthening layer 22 can withstand at least 5,000 grinding cycles with a conventional CS-17 grinding head without exposing the base layer 21. Furthermore, testing has shown that 7.5 kg of No. 20 diamond grit can be dropped from a height of 91.4 cm to impact the strengthening layer 22 without exposing the base layer 21.

[0030] The surface coating 2 includes a coloring layer 23, which can be formed on the strengthening layer 22. This coloring layer 23 is used to enhance the surface coating 2's coloring. For example, it can achieve a desired color using different metal coating materials. In this embodiment, the coloring layer 23 can be a titanium silicon carbide (TiSiC) layer, resulting in a metallic, dark blue appearance. The thickness of the coloring layer 23 can be 0.5 to 0.7 μm, further enhancing the high-brightness metallic appearance. Furthermore, using the Lab color space to evaluate the coloring of the club head body 1, the coloring layer 23 has an L value of 38 to 40, an a value of -4 to -5, and a b value of -9 to -11, indicating that the club head body 1 exhibits a metallic, dark blue appearance.

[0031] In summary, the surface-coated golf club head of the present invention, through the surface coating on the club head body, can further enhance the club head body's surface to a predetermined Lab value, thereby imparting a metallic luster to the semi-finished club head, thereby achieving a superior appearance. Furthermore, the surface coating imparts excellent wear resistance to the club head body, thereby enhancing durability.

[0032] Although the present invention has been disclosed using the preferred embodiments described above, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention. These changes and modifications are still within the technical scope protected by the present invention. Therefore, the scope of protection of the present invention shall include all changes within the meaning and equivalent scope of the appended claims.
