An oxidation study of plasma-enhanced chemical vapor deposited (PECVD) and rf sputtered hydrogenated amorphous silicon carbide (a-Si1-xCx:H) films was carried out using the infrared (IR) and electron spin resonance (ESR) techniques. a-Si1-xCx:H films with x=0.3, 0.5, and 0.8 were prepared with the PECVD method and significant oxide growth can only be obtained in a-Si0.2C0.8:Hfilm.
For this reason a PTA or laser carbide coating will have an average carbide size of approximately 200 µm (or 0.2 mm) and a carbide mass fraction of less than 60%. Furthermore the binder composition is limited to nickel-boron-silicon and nickel-chrome-boron-silicon alloys, with generally relatively low chrome content, therefore limiting the use of these coatings in certain corrosive environments.

Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The "feedstock" (coating precursor) is heated by electrical (plasma or arc) or chemical means (coustion flame). Thermal spraying can provide thick coatings (approx. thickness range is 20 microns to several mm, depending on the
