摘要

PURPOSE: A method of manufacturing a nozzle for a fuel injector is provided to have a good wear resistant and anti-corrosive by protecting a nozzle with a wear resistant layer and anti-corrosive layer.;CONSTITUTION: A method of manufacturing a nozzle for a fuel injector comprises the following steps. The multilayer bar having the circular layer(14) of the outside surrounding the inner core and is manufactured with the anti-corrosive material and an inner core(12) which is manufactured with the wear-resistance material formed into the longitudinal direction is formed. In order to form a cylindrical blank(16) having the flat front(18), the multilayer bar is cut in the longitudinal direction and the direction meeting at right angle. The tip(20) of the anti-corrosive material is fixed among the front of the blank on one.;COPYRIGHT KIPO 2012
