Laser surface modified materials and their incorporation into golf clubs

Abstract

Lasers are useful for many types of materials processing, including annealing, texturing, and joining. A method is provided for modifying the surface finish and structure of any material, with said materials being used in the construction of golf clubs. The surface modified materials have properties that lead to increased performance of the golf clubs. A secondary benefit is an improved material structure leading to a better feel for the golfer.

What is claimed is:  
     
         1 . A method for modifying the surface of a material with a laser comprising changes to the chemical, crystalline, or topographic structure of the material.  
     
     
         2 . The method of  claim 1 , wherein the material is any type of crystalline or non-crystalline ceramic material, including the classification of materials generally referred to as glasses.  
     
     
         3 . The method of  claim 1 , wherein the material is any type of crystalline or non-crystalline metal or metal-containing alloy.  
     
     
         4 . The method of  claim 1 , wherein the material is any type of polymeric or rubber material.  
     
     
         5 . The product of claims  1 - 4 , wherein the product comprises any surface on a golf club, preferably the striking face  
     
     
         6 . The product of claims  1 - 4 , wherein the product comprises a golf putter.  
     
     
         7 . The product of claims  1 - 4 , wherein the product comprises a golf iron.  
     
     
         8 . The product of claims  1 - 4 , wherein the product comprises a golf driver.
