Abstract:

Vendors literature has recommended the application of dry film lubricants to various aluminum and magnesium alloys. In order to evaluate these recommendations, combinations of several dry film lubricants applied to representative aluminum and magnesium alloys with various surface preparation procedures were tested. Of the combinations tested, the optimum combination of surface pretreatment and dry film lubricant in the case of 7075-T6 aluminum alloy was found to be Electrofilm 5396 lubricant applied to a hard coated surface. When testing HK31A magnesium alloy, the optimum combination was that of Electrofilm 5396 applied to a surface pretreated with a Dow 17 Type I coating, followed by Everlube 620 lubricant applied to the same pretreated surface.
