Abstract

The disclosure is directed to golf clubs with composite coatings for improved performance; features; economy; environmental, health and safety; and other factors. A golf club includes at least a head and a shaft, the shaft being attached to the head, the head having a ball striking surface, where at least a central portion of the ball striking surface is covered with a nickel-based coating, said nickel-based coating further comprises diamond particulates with a uniform distribution.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An improved golf club comprising at least a head and a shaft, the shaft being attached to the head, the head having a ball striking surface, wherein at least a central portion of the ball striking surface is covered with a nickel-based coating, and wherein said nickel-based coating further comprises diamond particulates with a uniform distribution, and said ball striking surface is of a Ra roughness of from 130 to 240. 
     
     
         2 . The golf club of  claim 1 , wherein said coating is a medium phosphorous coating. 
     
     
         3 . The golf club of  claim 1 , wherein said coating is a high phosphorous coating. 
     
     
         4 . The golf club of  claim 1 , wherein said coating is applied in a controlled electroless nickel plating bath. 
     
     
         5 . The golf club of  claim 1 , wherein said coating further includes particulate matter stabilizers. 
     
     
         6 . The golf club of  claim 1 , wherein said nickel-based coating is absent of heavy metals and PFAS materials. 
     
     
         7 . An improved golf club comprising at least a head and a shaft, the shaft being attached to the head, the head having a ball striking surface, wherein at least a central portion of the ball striking surface is covered with a nickel-based coating, and wherein said nickel-based coating further comprises diamond particulates with a uniform distribution. 
     
     
         8 . The golf club of  claim 7 , wherein said coating is a medium phosphorous coating. 
     
     
         9 . The golf club of  claim 7 , wherein said coating is a high phosphorous coating. 
     
     
         10 . The golf club of  claim 7 , wherein said coating is applied in a controlled electroless nickel plating bath. 
     
     
         11 . The golf club of  claim 7 , wherein said coating further includes particulate matter stabilizers. 
     
     
         12 . The golf club of  claim 7 , wherein said nickel-based coating is absent of heavy metals and PFAS materials.
