Influence of Process Variables on the Microstructure of Low Pressure

Low Pressure Plasma Spraying (LPPS) is a well established method of applying dense, adherent refractory alloys as protective coatings. However, little work has been done using LPPS to form coatings and free standing forms of tungsten with microstructures and densities approaching that of traditional powder consolidation techniques such as sinter forging.

Novel Hybrid Coatings

In order to address deficiencies in thermal spray coatings applied using air plasma spraying (APS) and high velocity oxygen fuel (HVOF), namely, adhesion, cohesion, porosity and line of sight limitations, novel hybrid coatings using post-thermal spray chemical vapor deposition via the pack cementation process were developed.
