We claim: 1. A method of using an aluminophosphate compound to decrease surface roughness, said method comprising: providing a precursor to an aluminophosphate compound, said precursor comprising aluminum ions and phosphate esters in a fluid medium; applying said precursor medium to a substrate selected from a bearing and a gear, said substrate having a first surface roughness value; and treating said applied medium for a time and at a temperature sufficient to provide a substantially amorphous aluminophosphate compound on said substrate, wherein the surface of said substrate is planarized and has a second roughness value decreased compared to said first surface roughness value. 2. The method of claim 1 wherein said medium is applied by a process selected from dip-coating, spraying, flow-coating and spin-coating. 3. The method of claim 1 wherein said treated substrate is exposed to one of an oxidation and corrosion inducing environment during one of processing and service. 4. The method of claim 1 wherein said substrate is selected from a steel, a nickel-based alloy, a superalloy, titanium, a titanium-based alloy, niobium, a niobium-based alloy, molybdenum and a molybdenum-based alloy. 5. The method of claim 1 wherein said surface roughness value is decreased by at least about 3-fold. 6. A method of using an aluminophosphate compound to decrease surface roughness for subsequent component deposition, said method comprising: providing a precursor to an aluminophosphate compound, said precursor comprising aluminum ions and phosphate esters in a fluid medium; applying said precursor medium to a substrate, said substrate having a first surface roughness value; treating said applied medium for a time and at a temperature sufficient to provide a substantially amorphous aluminophosphate compound on said substrate, wherein the surface of said substrate is planarized and has a second roughness value decreased compared to said first surface roughness value; depositing a biaxially-textured component selected from magnesium oxide, yttria and yttria stabilized zirconia on said aluminophosphate compound; and depositing an electromagnetic component on said textured component. 7. The method of claim 6 wherein said medium is applied by a process selected from dip-coating, spraying, flow-coating and spin-coating. 8. The method of claim 6 wherein said electromagnetic component is a superconducting YBCO layer. 9. The method of claim 6 wherein said surface roughness value is decreased by at least about 3-fold.
