US Patent 11752401 Method for optimizing launch characteristics of a golf club

A method of enhancing surface strike performance, includes providing a club head having a face surface and a receiving portion recessed into the club face. The receiving portion is configured to receive a strike surface material. The surface strike material is an amorphous ceramic material which is inserted as an inlay into the receiving portion as a liquid slurry. The slurry is distributed evenly within said receiving portion forming a uniform layer of ceramic material filling said receiving portion. Microgrooves are added to the ceramic material in a vertical direction to further increase the strike performance of the club head.
