Abstract
In recent years, the use of plasma-sprayed protective coatings has
gained increasing acceptance for prolonging the service life of critical
components exposed to aggressive environments during normal
operation. This paper is aimed at providing an overview of the current
state-of-the-art· of the plasma coating technology. It includes a brief
discussion of the various important aspects associated with the development
of reliable protective coatings as well as their evaluation,
and outlines some noteworthy advances made in the field of plasma
spray materials and equipment in the past few years. The various
factors influencing the coating quality are identified and the wideranging
utility of plasma-sprayed coatings is also highlighted.
