Abstract
The effects of pre-sintering and infiltration conditions on the electrical and physical properties of Cu-Cr contact material have been studied. Specimens were prepared by infiltration technique, aiming at the final composition of Cu50w%Cr, with varying pre-sintering and infiltration conditions. It showed that increased pre-sintering temperature had a little influence on the final microstructure of Cu-Cr contact material, but improved the surface morphology of Cr-skeleton resulting in better wettability in the followed infiltration process. It also showed that Cr grain growth and gram shape change became prominent with increasing infiltration temperature and time.
