Description

Golf club head surface treatment method

The present invention relates to a method of manufacturing a golf club head, and more particularly to a method of treating a club head surface that is subsequently performed on a formed club head in the golf club head manufacturing method.

The golf club head made of carbon steel has rust due to carbon steel, and the club head is aesthetically pleasing. Therefore, the existing carbon steel golf club heads will be surfaced by means of electroplating or plasma plating. deal with. among them:

In terms of electroplating technology, it is coated with a high-silver nickel (Ni) or chromium (Cr) coating on the surface of a carbon steel club head. The thickness of the nickel coating is about 20~25μm, and the thickness of the chrome coating is about 3~8μm. However, the surface treatment method of this plating method is due to the use of heavy metal chemicals, environmental pollution and problems affecting the human body, and the plating formed on the surface of the club head is not firmly integrated with the club head itself, the club After the head is used for a period of time, the problem of peeling off the coating is easy to occur. Furthermore, the nickel and chrome coating can only make the surface of the club head appear high silver, and the surface of the club head cannot be dark or dark brown.

As far as the plasma coating technology is concerned, although the surface of the club head can exhibit a dark appearance such as iron gray or black, the plasma plating technique is applied to the surface treatment of the club head, and there is a problem of high cost. The plasma plating technique only forms a black coating having a thickness of about 1 to 5 μm on the surface of the club head, and the coating has poor corrosion resistance and wear resistance.

The main object of the present invention is to provide a method for treating the surface of a golf club head, and to improve the existing technical methods such as electroplating and plasma plating, which can not make the club head have good appearance, good corrosion resistance and wear resistance, etc. problem.

In order to achieve the foregoing objective, the golf club head surface treatment method of the present invention comprises: providing a carbon steel formed club head; a step of grinding the club head; and cleaning the polished club head; a step of inspecting the appearance of the cleaned club head; applying a sandblasting effect to the surface of the club head to form a uniform rough surface of the club head surface; and cleaning the club head after the sandblasting; The step of moving the club head on the clamp to transfer the club head; the step of preheating the club head on the fixture; and performing a nitriding step on the preheated club head to form a wear resistance of the club head surface layer a corrosion-resistant nitrogen compound layer; performing a first oxidation step on the nitriding club head to cause an oxide film on the surface of the club head due to oxidation; a cooling and cleaning step of the club head; Removed from the fixture, applying a sandblasting or polishing step to the club head to remove the loose layer on the outside of the nitrogen compound layer of the club head; the step of reinstalling the club head in the fixture; pre-preparing the club head in the fixture Hot step to make the club head Over 350 ℃ ~ 400 ℃ environment of the club head preheated to a predetermined temperature; a second step of oxidizing the club head, the club head face to produce Dark oxide film; the step of cooling and cleaning the club head, the surface of the club head is washed with water, and the club head is cooled and cooled; the drying step of the club head; the polishing step is applied to the club head, so that The club head presents a uniform black surface appearance; the club head is subjected to an oil immersion treatment step, the club head is preheated and then immediately immersed in the rust preventive oil, and the club head is taken out from the rust preventive oil, and then the dry cloth is removed. Wipe clean; visually inspect the club head after oil immersion treatment to complete the surface treatment of the club head.

By the technical means of the surface treatment method of the club head, the invention has the following characteristics compared with the technical means of conventional electroplating or plasma plating:

1. Low pollution, low pollution, in line with environmental protection: The present invention utilizes nitriding and second-order oxidation and other auxiliary steps to carry out the process of treating the surface of the club head, thereby greatly reducing the use of chemical agents, so the invention can be effective Reduce pollution and pollution, in line with environmental protection.

2. Good corrosion resistance and wear resistance: the invention utilizes nitriding and second-order oxidation to provide excellent corrosion resistance and wear resistance to the surface of the club head, and provides good protection against the surface of the club head of carbon steel. Rust function.

3. In the case of no surface peeling: the present invention forms a nitrogen compound layer and an oxide film by infiltration of nitrogen into the surface of the club head by means of nitriding and second-order oxidation, and the nitrogen compound layer and the oxide film layer are both with the club head. It is produced by the combination of nitrogen and oxygen with elements in the carbon steel material, and is not simply coated on the surface of the club surface, so there is no surface peeling.

4. No change in weight and shape of the club head after surface treatment: As described above, the present invention utilizes nitriding and second-order oxidation to form a nitrogen compound layer and an oxide film due to the infiltration of nitrogen into the surface of the club head. The coating formed on the surface of the club head is not applied, so the weight and outer dimensions of the club head itself are not changed.

5. The appearance of the club head is good: the invention can make the surface of the club head form a black, dark blue or dark brown bright color, so that the club has a more beautiful appearance.
