ABSTRACT:
A method of ceramic coating a substrate by thermodeposition from a sol made by hydrolyzing and peptizing organometallic compounds in water. The sol contains colloidal particles having a size between about 0.0005 micron and about 10 microns and the deposited coatings have good packing characteristics as well as smoothness. Composite coatings are also deposited which contain reinforcing materials such as SiC embedded in the coated matrix. These coatings afford the substrate onto which they are coated excellent wear, anti-corrosion and insulating characteristics.
