ABSTRACT:
A golf club which generally includes a shaft, a grip and a clubhead, which includes a sole, a back and a clubface. The surface layer of the clubface of the golf club is a substantially harder material than the material generally comprising the clubhead. The process for imparting the substantially harder material onto and to become a part of the surface layer of the clubface generally includes micro-welding an electrode material to the surface of the clubface. The micro-welding process can be any one of a number of known micro-welding processes, such as electro-spark deposition, or others. The electro-spark deposition process generally includes the utilization of an electrode, through which short duration, high amperage charges are directed through the electrode and the clubhead. Extremely short duration discharges at high discharge frequencies result in deposition of the electrode material onto the clubface of the golf club, such that it becomes micro-welded.
