    • 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.
    • 一种高尔夫球杆,通常包括一个轴,一个把手和一个球棒头,它包括鞋底,背部和杆面。 高尔夫球杆的杆面的表面层是比通常包括杆头的材料基本上更硬的材料。 将基本上较硬的材料赋予并且成为球棒表面的一部分的方法通常包括将电极材料微焊接到球棒表面的表面。 微焊接工艺可以是许多已知的微焊接工艺中的任何一种,例如电火花沉积等。 电火花沉积工艺通常包括利用电极,通过该电极,短时间,高电流强度的电荷穿过电极和杆头。 在高放电频率下的持续时间短的放电导致电极材料沉积到高尔夫球杆的杆面上,使得其变成微焊接。
