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.
