Abstract

The Axial III; launched in 1994; is a patented plasma spray torch with axial injection of feedstock. In comparison to the traditional radial injection; axial injection technology has proven to offer greater deposition efficiency; throughput; and cost savings on numerous applications [1]. Despite these benefits; the original Axial III M600 torch had several limitations due to its size; mass; and number of components. To address these shortcomings; a smaller; lighter; and more ergonomic version of the torch was developed; called the Axial III Plus; that produces the same high-quality coatings at high feed rates and deposition efficiency. This paper highlights the innovations in this new torch and the potential applications it opens for the plasma spraying industry.
