Abstract

The applicability of the ion plating process for deposition of tribological coatings was surveyed.Coatings chosen for the experimental work were aluminium bronze and titanium nitride.The former being deposited by triode ion plating and the latter by reactive triode ion plating.A slug feed resistive evaporation method was introduced for the ion plating of copper-aluminium alloy coatings.The structure and tribological properties of the various coatings produced with different evaporation rates and ion bombardment conditions were studied.The beneficial effects of the interrupted growth resulting from the pulsed evaporation induced by a slug feeding mechanism have been demonstrated.The tribological properties of ion plated titanium nitride coatings have been evaluated both in laboratory tests and industrial metal working processes.An abrasive wear mechanism for hard coatings on soft substrates has been suggested, and the benefits of titanium nitride coating for wear protection have been shown.Also the commercial applicability of this coating for industry has been reviewed.
