Low temperature HVOF Process and its potential Applications

High-performance metallic coatings find wide applications in industries due to the high density and the low oxide content. Conventional processes like vacuum plasma spraying (VPS) and cold spraying (CS) entail some problems with either high production costs or process limits. In this paper, a novel process, low-temperature HVOF (LT-HVOF), is developed by decreasing the plume temperature and increasing the plume velocity on the basis of the conventional HVOF and the microstructure, the coating properties and some potential applications for LT-HVOF-sprayed metallic coatings are presented in the paper. These coatings serve as thermal conductive, corrosion-resistant and oxidation-resistant coatings.
