Abstract
The present invention is directed to compositions derived from polymers containing metal-nitrogen bonds, which compositions exhibit, among other things, desirable oxidation resistance, corrosion resistance and hydrolytic stability when exposed to adverse environments, whether at ambient or at elevated temperatures, and which may be useful as, for example, protective coatings on surfaces.

A method for forming a coating on at least a portion of at least one substrate material, comprising the steps of:
- A) combining (1) at least one boron source material and (2) at least one metal-nitrogen polymer composition comprising at least one silicon-nitrogen polymer selected from polyureasilazanes and polythioureasilazanes, to form a mixture;
- B) placing said mixture onto at least a portion of at least one substrate material;
- and
- C) heating said at least one substrate material having said mixture thereon to cause said mixture to react to form a coating on at least a portion of said at least one substrate.
A method for forming a coating on at least a portion of at least one substrate material, comprising the steps of:
- A) combining (1) at least one boron source material, and (2) at least one metal-nitrogen polymer composition comprising at least one silicon-nitrogen polymer selected from polyureasilazanes and polythioureasilazanes, to form a mixture;
- B) heating at least a portion of said at least one substrate material;
- and
- C) placing said mixture onto at least a portion of said at least one heated substrate material to cause said coating to form.
A protective coating composition comprising:
- (A) at least one component comprising at least one boron source material and
