Abstract
A method of treating the surface of a substrate by thermally spraying large size particles, >10 micrometers, of a composition such as a metal hydroxide, carbonate, or nitrate directly onto the substrate whereby a small size particle coating, <5 microns and more particularly <3, is formed on the substrate, enhancing the surface area and porosity properties of the substrate, and substrates with metal oxide surfaces produced thereby.
Claims10
A method for providing a mechanically bonded layer of metal oxide particles having a particle size distribution in the nominal distribution range of less than approximately 5 microns to the surface of a metal substrate comprising:
- thermally spraying a homogenous particle composition selected from the group consisting of metal hydroxide, metal carbonate, metal nitrate, transition metal hydroxide, transition metal carbonate, transition metal nitrate, rare earth metal hydroxide, rare earth metal carbonate, and rare earth metal nitrate particles, directly onto the surface of the metal substrate.
A method for providing a mechanically bonded layer of metal oxide particles having a particle size distribution in the nominal distribution range of less than approximately 5 microns to the surface of a metal substrate comprising:
- plasma spraying a homogenous particle composition selected from the group consisting of metal hydroxide, metal carbonate, metal nitrate, transition metal hydroxide, transition metal carbonate, transition metal nitrate, rare earth metal hydroxide, rare earth metal carbonate, and rare earth metal nitrate particles, directly onto the surface of the metal substrate.
