摘      要：The lap joint of T2 copper plate and 1060 pure aluminum plate was made by using the plasma arc welding method with adding Fe_(2)O_(3)nanoparticles in different *** research analysis found that the thickness of the IMC(intermetallic compound)and eutect-ic region decreased after the addition of nanoparticles due to its inhibitory *** the proportion of Fe_(2)O_(3)nanoparticles is 3%,the in-terface intermetallic compound layer is the ***,after this ratio is continuously increased,the inhibition effect is weakened by the agglomeration of nanoparticles,and the thickness begins to increase *** mechanical and electrical properties of the joint are mainly affected by the thickness of the IMC *** nanoparticles are agglomerated into large particles with high ***,the tensile strength and relative electrical conductivity of the joint are first increasing and then decreasing with the increase of nanoparticle *** the proportion of nanoparticles is 3%,the tensile strength and electrical conductivity are maximum.
