【Abstract】 PM enterprises together their research institutes both at home and abroad have done much research work on the flowability of metal powders for making structural auxiliary parts for a long time in the past.However,nothing is reported about the research of the flowability of mixed powders for making PM electric contacts.With the progress of the automation of forming PM electric contacts,the improvement of the flowability of the mixed powders is required so as to ensure the quality of the compacted blanks and raise the productivity of the forming of the contacts.This paper has done some work in this respect.更多还原
