Influence of Apparent Contact Area on Wear Properties of Hard-Drawn Copper Contact Wire and Iron-Based Sintered Alloy Contact Strip under Electric Current Flowing Condition

We carried out wear tests with material combination of a hard-drawn copper contact wire and an iron-based sintered alloy contact strip by changing the apparent contact area with four steps to clarify the influence of the apparent contact area on wear properties under electric current flowing conditi...
