Abstract

A golf club head and method for making the same, which is characterized in that: a surface of the golf club head comprises a base layer made of non-ferrous metal of aluminum, or magnesium, or titanium, or an alloy base layer of those three metals and a protection layer after the surface of the golf club head is processed, and the thickness of the protection layer is 10-100 μm. The protection layer is a ceramic layer formed by plasma micro-arc oxidation and has the properties of abrasion-resistant and corrosion-resistant. The technique is simple, and the production cycle is short, Thereby, the production efficiency is improved.

Claims

1. A golf club head comprising a metal base layer, characterized in that:

a surface of the metal base layer is covered with a ceramic protection layer.

2. The golf club head as claimed in claim 1 characterized in that:

the ceramic protection layer is formed after the metal base layer is processed with plasma micro-arc oxidation.

3. The golf club head as claimed in claim 1 characterized in that:

the thickness of the ceramic protection layer is 10-100 μ

m.

4. The golf club head as claimed in claim 1 characterized in that:

the metal base layer is an aluminum metal base layer, a magnesium metal base layer, a titanium metal base layer, or an alloy base layer of these three metals.

5. A method for making such a golf club head comprises the following steps:

firstly, making a golf club head;

secondly, burnishing the golf club head and then degreasing and cleaning it;

thirdly, forming a ceramic protection layer by plasma micro-arc oxidation of the golf club head.

6. The method for making such a golf club head as claimed in claim 5 characterized in that:

the method of making the golf club head in the first step includes precision molding and forging.

7. The method for making such a golf club head as claimed in claim 5 characterized in that:

in the second step, the manufactured golf club head is degreased by weak alkaline, and then cleaned and dried.

8. The method for making such a golf club head as claimed in claim 5 characterized in that:
