Initial Damage Mechanism and Running-In Behaviour of Phosphate Conversion Coatings

Abstract:

This work is focused on the damage and wear mechanisms of phosphate conversion coatings which were deposited onto steel substrates by a wet-chemical process. For studying the damage mechanism, sets of multiple scratches were performed. Scratch tests along with SEM micrographs revealed the early damage mechanisms as well as the running-in friction and wear behaviour of phosphate conversion coatings. The deeper understanding allows to increase tribological performance in terms of controlled friction and wear resistance of technical components. This way, promising measures in reduction of seizing and increase of lifetime for such components could be developed.
