Abstract
Aluminophosphate compounds and compositions as can be used for substrate or composite films and coating to provide or enhance, without limitation, planarization, anti-biofouling and/or anti-microbial properties.
Claims9
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.

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.
