PIN MATERIAL FOR DOT PRINTER

摘要

PURPOSE:To obtain a pin material for a dot printer generating little printing noise and having superior wear resistance and toughness by nitriding the surface of an Ni-Ti alloy as a pin material for a dot printer so as to increase the surface hardness. CONSTITUTION:The surface of an Ni-Ti alloy consisting of 54-57wt% Ni and the balance Ti as a pin material for a dot printer is nitrided to form a hard nitride layer. A pin material for a dot printer having superior wear resistance and increased mechanical strength is obtd. by forming the hard nitride layer.
