Abstract
A wedge type golf club head with improved performance characteristic is disclosed herein where at least a striking surface of the wedge type golf club head is coated with a polymer coating to decrease the coefficient of friction as well as create a hydrophobic surface to remove dirt and debris. More specifically, the present invention discloses a wedge type golf club head with a hydrophobic polymer coating that creates a contact angle of greater than about 90 degrees as well as decreases the coefficient of friction to be less than about 0.1.
Claims17
A wedge type golf club head comprising:
- a forward portion, and
- an aft portion,
- wherein said forward portion further comprises,
- a striking surface for striking a golf ball,
- a plurality of grooves placed horizontally across said striking surface, and
- a polymer coating covering at least said striking surface,
- wherein said polymer coating has a thickness of from about 300 microns to about 700 microns,
- wherein said wedge type golf club head has a loft angle of greater than about 45 degrees,
- wherein said polymer coating has a hydrophobic coefficient of friction ratio of less than about 0.001, and
- wherein said hydrophobic coefficient of friction ratio is defined as a ratio of a coefficient of friction of said polymer coating divided by a contact angle of said polymer coating.
The wedge type golf club head of 3, wherein said coefficient of friction is less than about 0.08.
A method of creating a wedge type golf club head with improved performance comprising:
- coating at least a striking surface of said wedge type golf club head with a polymer coating,
- wherein said wedge type golf club head has a loft angle of greater than about 45 degrees,
- wherein said polymer coating has a thickness of from about 300 microns to about 700 microns,
- wherein said polymer coating has a hydrophobic coefficient of friction ratio of less than about 0.001, and
- wherein said hydrophobic coefficient of friction ratio is defined as a ratio of a coefficient of friction of said polymer coating divided by a contact angle of said polymer coating.
