Abstract
Refractory coated fabric compositions having a thickness substantially thinner than those prepared heretofore can be provided by forming the refractory coating by a plasma spraying technique.
Claims17
A method of preparing a flexible refractory coated fabric composition which comprises:
- (a) developing a thermal plasma spray,
- (b) introducing finely divided refractory materials into said thermal plasma spray, and
- (c) directing said thermal plasma spray at the exposed surface of a non-rigid base fabric whereby a coating of said refractory materials is formed on said fabric, said refractory materials being capable of fusing with said fabric at elevated temperatures.
