Influence of sulfides on the tribological properties of composites produced by pulse electric current sinteringSeung Ho KimDepartment of Electronics Engineering,Dankook University摘 要:pulse electric current sintering(PECS) technique.The coefficient of friction(COF) of the Al2O3-15wt% ZrO2 composite without/with sulfides was in the range of 0.37-0.48......
sintered only by an intensive pulse electric current are the maximum. When the total sintering time keeps constant, the properties of the sintered alloys can be obviously improved by optimizing the sintering... electric current activated sintering (ECAS) technique, also known as spark plasma sintering, was quickly developed, which is in essence an intensive pulse electric current sintering. ECAS is seen......
to the experiments without current. The frequency has a more significant influence on bending force and springback than electric current density. Electroplastic(EP) effect begins to work when pulse current... of Mechanics and Mechatronic Equipment, Shandong University摘 要:In this work, the influence of pulse current parameters on springback and bending force of magnesium......
