Cu-Sn-MoS_2 composite layer was formed on the sliding surface of automotive component "rackguide" by pulsed current pressure sintering process. The substrate of the rackguide was sintered simultaneously with the mixtured metal powder corresponded to A2014 aluminum alloy. Microstructure observation by OM and SEM, rockwell hardness test, friction test and dimensional measurement of the sintered specimen were carried out. Main results obtained were as follows : (1) Neither cracks nor pores were observed in the sliding surface and the substrate of the rackguide. (2) The shape of the top on the rackguide was deformed by forming of the sliding surface layer on the rackguide. But this deformation of the rackguide could be corrected by using the plastic forming process.
