Abstract
It was confirmed that manganese phosphate-based coatings decrease considerably the coefficient of dry sliding friction. Better results are obtained when both parts are phosphated. The effect of load on the friction coefficient was established, indicating a different mechanism of friction from that of metals. It is suggested that friction of phosphate coatings is similar to that of relatively soft metal coatings on the one hand and certain brittle substances such as rocksalt on the other hand, with considerable contribution of abrasion wear, particularly in the running-in period. No visible effect of chemical pretreatment, friction velocity (within the examined limit) and coating unit weight (above certain critical value) on the dry friction coefficient value has been observed.
