Pip and Crater Erosion in DC Applications,New Research and Review

摘要：

　　A review of previous work plus new research done on pip and crater erosion has been described in this paper.This includes a discussion of factors that both promote or decrease the probability of forming pip and crater erosion during contact switching.New data is shown from tests done on comparing silver tin indium oxide and hard silver, 99.85% Ag 0.15% Ni contacts for pip and crater erosion.The silver tin indium oxide shows lower erosion and less pip and crater transfer on higher DC voltage testing than lower voltages.The hard silver material shows a high erosion rate and a more mound and valley shaped pip and crater formation than the sharp pips that form with silver tin indium oxide.
