Abstract

The high power plasma torch (PlazJet) can be used to spray refractory ceramics with high spray rates and deposition efficiency, It can provide dense and hard coating with high bond strengths, When manufacturing thermal barrier coatings, the PlazJet gun is well adapted to spraying the ceramic top coat but not the MCrAlY materials that are used as bond coat, Are spraying can compete with plasma spraying for metallic coatings since cored wires can be used to spray alloys and composites. In addition, the high production rate of are spraying enables a significant decrease in coating cost. This paper discusses the performances of the PlazJet gun, and a twin-wire are spraysystem, and compares the properties and cost of MCrAlY coatings made with these two processes. For are spraying, the use of air or nitrogen as atomizing gas is also investigated.
