Abstract:

Epoxy and polyamide plastic coatgs applied on Al by the fluidized bed process were tested without lubrication for wear and friction in sliding contact with a like plastic, anodized Al, and Cdplated steel. Ambient temperature range of tests was minus 65 to 160 F, maximum load was 600 psi and maximum speed was 5 fpm. Polyamide coating showed negligible wear, with friction coefficients from .13 to .26. Epoxy coatings showed wear grooves with a maximum depth of .003 in. and with friction coefficients between .05 and .50. Addition of flake graphite to the epoxy coating increased friction. Application of the polyamide coating required a preheat temperature of 750 F, which precludes its use on heat treated aluminum. Author
