  • Publication number: 20240091603
    Abstract: A golf club head having a striking face having improved abrasion resistance by applying abrasion resistant material to the striking face. Applying abrasion resistant material to the striking face can include the use of electroplating a metal onto the striking face, such as chromium. The striking face can be co-molded with a conductive veil to improve the electroplating process. A physical vapor deposition layer can be further applied to the striking face. Alternatively, a veil can be applied directly to the striking face without electroplating. The veil can be made from compounds such as carbon, aramid, polyetherimide, polyphenylene sulfide, polyether ether ketone, polypropylene, and metals, such as copper.

  • Publication number: 20240091602
    Abstract: A small-format metal wood golf club head may include a first portion including at least a striking face formed of an alloy of titanium and a second portion including at least a portion of a sole formed of an alloy of steel. The golf club head exhibits beneficial characteristics of both titanium and steel in that the titanium striking face is lighter than a steel striking face having the same coefficient of restitution (COR) and the steel sole allows for concentration of mass in a beneficial location within the golf club head, while overcoming traditional difficulties in bonding titanium and steel.
