Oxidation Resistant Coating on Carbonaceous Surface - A simplified explanation of the abstract

This abstract first appeared for US patent application 18383530 titled 'Oxidation Resistant Coating on Carbonaceous Surface

Simplified Explanation

The patent application describes methods for providing an oxidation resistant coating on a carbonaceous surface, involving applying a phosphate-borate solution to form a first layer, applying a CeO—AlO solution to form a second layer, and applying the phosphate-borate solution to an outermost surface portion of the second layer. The protective coating consists of a first layer of phosphate-borate material, a second layer of CeO—AlO, and additional phosphate-borate material on the outermost surface portion of the second layer.

The method involves applying a phosphate-borate solution to create a first layer on the carbonaceous surface.
A CeO—AlO solution is then applied to form a second layer on top of the first layer.
Additional phosphate-borate material is applied to the outermost surface portion of the second layer.
