Friction and contact resistance of a junction between a palladium silver alloy and an iron nickel alloy
Friction and contact resistance measurements are presented as functions of normal load, electroplated material, and liquid lubricant for an electrical contact junction between a palladium silver alloy and an iron nickel alloy. An instrument for the simultaneous measurement of the frictional force and the contact resistance was constructed and is described. The results show that, under high normal loads, an iron nickel alloy plated with nickel is preferable to one plated with gold over nickel. High friction and excessive wear result from the unlubricated wiping closure of the gold-plated contacts and should be avoided. Both contact resistance and friction wre exceptionally low for contacts which were lubricated by an amalgam formed in situ.
