Golf tee and method for making the same

Abstract

An exemplary golf tee ( 100 ) includes a substrate ( 100 a ) and a coating film ( 100 b ). The substrate is made of metal or metal alloy. The coating film is formed on an outside surface of the substrate. The present invention also provides a method for making the exemplary golf tee. The method includes providing a roughcast made of metallic or metallic alloy material; forming the substrate by a method of die-casting with the roughcast; and forming the coating film on an outside surface of the substrate by a method of surface treating.

1 . A golf tee, comprising:
 a substrate made of metal or metal alloy; and   a coating film formed on an outside surface of the substrate.   
   
   
       2 . The golf tee as claimed in  claim 1 , wherein the substrate is formed by die-casting. 
   
   
       3 . The golf tee as claimed in  claim 1 , wherein the coating film is formed by a method of surface treating. 
   
   
       4 . The golf tee as claimed in  claim 3 , wherein the surfacing treating is one of a group of galvanization, microarc oxidation, physical vapor deposition, and anode oxidation technology. 
   
   
       5 . The golf tee as claimed in  claim 1 , wherein the substrate of the golf tee is made of magnesium alloy. 
   
   
       6 . The golf tee as claimed in  claim 1 , wherein the substrate of the golf tee is made of zincum alloy or aluminium alloy. 
   
   
       7 . The golf tee as claimed in  claim 1 , wherein the golf tee comprises at least one figure formed on a surface of the golf tee. 
   
   
       8 . The golf tee as claimed in  claim 1 , wherein the coating film is made of chrome, gold, nickel, copper, or silver. 
   
   
       9 . A method for making golf tees, comprising:
 providing a roughcast made of metallic or metallic alloy material;   forming a substrate by a method of die-casting with the roughcast; and   forming a coating film on an outside surface of the substrate by a method of surface treating.   
   
   
       10 . The method of making golf tees as claimed in  claim 9 , wherein melted liquid of the roughcast is poured into a mold cavity, compressed under pressure and cooled, thus forming the substrate. 
   
   
       11 . The method of making golf tees as claimed in  claim 9 , wherein the coating film with material of chrome, gold, nickel, copper, or silver is plated on the outside surface of the substrate by galvanization. 
   
   
       12 . The method of making golf tees as claimed in  claim 9 , wherein the coating film is formed by microarc oxidation, physical vapor deposition, or anode oxidation technology. 
   
   
       13 . The method of making golf tees as claimed in  claim 9 , wherein the substrate of the golf tee is made of magnesium alloy. 
   
   
       14 . The method of making golf tees as claimed in  claim 9 , wherein the substrate of the golf tee is made of zincum alloy or aluminium alloy. 
   
   
       15 . The method of making golf tees as claimed in  claim 14 , wherein at least one figure is formed on the golf tee during forming the substrate by die-casting. 
   
   
       16 . The method of making golf tees as claimed in  claim 9 , wherein the coating film is made of chrome, gold, nickel, copper, or silver.
