Golf Club Head and Method for Making the Same

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.

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 μm. 
   
   
       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: a power source of the micro-arc oxidation technique of the third step is provided with a constant voltage and current controlling device; the range of the output voltage is 0˜600V; the capacity of the output current is 0˜12 A/dm2; and the time of micro-arc oxidation is 10˜60 minutes. 
   
   
       9 . The method for making such a golf club head as claimed in  claim 5  characterized in that: an electrolyzed solution used in the micro-arc oxidation of the third step is K 2 O.nSiO 2  and Na 3 P 2 O 7 , and the temperature is 10˜45° C. 
   
   
       10 . The method for making such a golf club head as claimed in  claim 5  characterized in that: the thickness of the ceramic protection layer formed after the surface of the golf club head is processed with plasma micro-arc oxidation of the third step is 10-100 μm.
