Abstract
A coating method comprising coating a metal having a metal oxide film with a refractory metal oxide using an aqueous slurry containing said refractory metal oxide, which is characterized in that said refractory metal oxide has an average particle diameter ranging from 0.7-3 microns.
Claims12
A coating method comprising immersing a metallic carrier having a metal oxide film in an aqueous slurry, said slurry containing a refractory metal oxide having an average particle diameter of 0.7 to 3 microns and a sol of a refractory metal oxide wherein the weight ratio of the refractory metal oxide having an average particle diameter of 0.7 to 3 microns to the refractory metal oxide in the sol is 30:1 to 8:1, blowing off the surplus slurry from the carrier, drying the carrier and calcining the carrier.
A coating method comprising coating an aluminum-containing ferritic stainless steel alloy with an aqueous slurry of a refractory metal oxide having an average particle diameter ranging from 0.7 to 3 microns, said aqueous slurry also containing a sol of a refractory metal oxide and drying.
A coating method comprising coating an aluminum-containing ferritic stainless steel alloy with an aqueous slurry of active alumina having an average particle diameter ranging from 0.7 to 3 microns, said aqueous slurry also containing a sol of active alumina and drying.
