METHOD AND APPARATUS FOR PRODUCING A COATING ON A SUBSTRATE

摘要

The invention relates to the use of an atomiser to inject a coating material typically in the form of a liquid / solid particulate slurry into a sub-atmospheric pressure plasma to generate a high flux of excited coating forming material that permits the rapid deposition of a composite coating onto a substrate. The use of plasma discharges at reduced pressures results in the more efficient consumption of process precursors and gases, a reduced risk of explosion compared to atmospheric pressure processes and facilitates the removal of volatile components from the deposited composite coatings prior to their use.
