Abstract
A golf club component is coated with a corrosion-resistant, wear-resistant, impact-resistant material, such as zirconium nitride, titanium nitride, di-titanium nitride, titanium aluminum nitride, titanium carbonitride, titanium zirconium nitride, or titanium aluminum carbonitride. Deposition is preferably accomplished by a cathodic arc process using linear deposition sources with simultaneous heating and rotation of the golf club component substrate relative to the deposition sources.
Claims20
A method for preparing a golf club component, comprising the steps of providing a golf club component substrate made of a first material being a first metal;
- and
- applying a coating structure to the golf club component substrate, the step of applying a coating structure including the steps of
- coating a first layer of a second material of only a second metal overlying and contacting the substrate, said second material being different than said first material, and
- coating a second layer of a third material overlying and contacting said first layer, the third material being homogeneous and including a third metal selected from a group consisting of vanadium, chromium, zirconium, titanium, niobium, molybdenum, hafnium, tantalum, and tungsten, and a nonmetal selected from a group consisting of nitrogen and carbon, wherein the second layer is not a mixture or alloy of the third material with cobalt or nickel.
A golf club component, comprising
- a golf club component substrate made of a first material being a first metal and having a surface, the golf club component substrate being selected from a group consisting of a golf club shaft and a golf club head;
- and
- a coating structure overlying and contacting the golf club component substrate, the coating structure comprising
- a coating of a first layer of a second material of only a second metal overlying and contacting at least a portion of the surface of the club component substrate, said second material being different than said first material, and
- a coating of a second layer of a third material overlying and contacting said first layer, the third material being homogeneous and including a third metal selected from a group consisting of vanadium, chromium, zirconium, titanium, niobium, molybdenum, hafnium, tantalum, and tungsten, and a nonmetal selected from a group consisting of nitrogen and carbon, wherein the second layer is not a mixture or alloy of the third material with cobalt or nickel.
