Abstract
In examples, a method for forming a high temperature coating includes applying a barrier coat formulation on a substrate. The barrier coat formulation includes mono-aluminum phosphate; boron carbide; and molybdenum or a molybdenum compound. The method further includes heat treating the barrier coat formulation to form an oxidation-resistant coating layer, wherein a melting point of the oxidation-resistant coating layer is greater than about 800 degrees Celsius (° C.).
Claims14
A method for forming a high temperature coating, the method comprising:
- applying a barrier coat formulation on a substrate, wherein the barrier coat formulation comprises:
- mono-aluminum phosphate;
- boron carbide;
- and
- molybdenum or a molybdenum compound,
- heat treating the barrier coat formulation to form an oxidation-resistant coating layer, wherein the oxidation-resistant coating layer comprises a glassy mono-aluminum phosphate matrix with the boron carbide and the molybdenum or the molybdenum compound homogeneously dispersed therein, and wherein a melting point of the oxidation-resistant coating layer is at least about 1,000 degrees Celsius (° C.).
