Plasma spray deposition of MCrAlY coatings for corrosion resistance and rub tolerance on gas turbine blades, vanes and seal surfaces has received a great deal of attention in recent years. While most of the literature has described coatings produced with low pressure spray systems, substantial advantages can be realized using inert gas shrouded torches operating in the open air. This paper discusses some of these advantages and describes the coatings produced with efficient argon shrouded torches. In addition, specific examples of production MCrAlY and thermal barrier coatings are given.
