Effect of Polyethylene Glycol on the Mechanical Alloying Behavior of Cu-W Electrical Contact Material

Abstract: In this study, the effect of polyethylene glycol on the particle size and morphology of Cu25W composite powder was investigated. For this purpose, commercial elemental copper and tungsten powders were milled in a planetary-type ball mill. Milling conditions, namely ball-to-powder weight ratio and milling speed, were selected to be 10:1 and 300 rpm, respectively. In order to avoid agglomeration and to decrease the tendency of cold welding among powder particles, polyethylene glycol at the amount of 2 wt% was us… Show more

“…PCAs are basically used to establish a balance between cold welding and fracturing events and the non-use of the PCAs leads excessive cold welding which inhibits further size reduction, especially in compositions containing a substantial fraction of ductile component. Much work has been done towards producing and evaluating the electrical performances of contact materials [6][7][8][9][10][11][12][13][14][15]. However, studies regarding the type of PCA on the characterization of composite powders containing noble metals, especially silver are very limited.…”
