FRICTION AND WEAR PROPERTIES OF PLASTIC COATINGS APPLIED BY THE FLUIDIZED BED PROCESS

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)
