    摘要： Coatings which protect the skin of hypersonic flight vehicles are disclosed. Silicide coatings, such as R512E, is used to minimize catalytic recombination of dissociated species, such as atomic oxygen and atomic nitrogen, thus, decreasing thermal and oxidative degradation. Prehydrated, polymerized sol of tetraethylorthosilicate is applied to a coating, and is fired, to produce an integral protective coating.

    摘要： A single or multilayer smart susceptor for temperature control of part fabrication in an induction processing system generally consists of single layer or laminated layers of ferromagnetic material susceptible to heating by induction. The use of the susceptors in fabrication at elevated temperatures causes oxidation damage to the surface. The susceptor may be coated with a nickel aluminide surface coating to minimize oxidation of the susceptor outer surface.

    摘要： In one embodiment a method to join a first structure to a second structure, comprises aligning a first hole in the first structure with a second hole in the second structure and inserting a fastener into the first hole and the second hole. The fastener comprises a shape memory alloy which was formed into a first shape having a diameter slightly larger than a diameter of the first hole and the second hole when the shape memory alloy was in an austenite state and reduced to a second shape having a diameter less than the diameter of the first hole and the second hole when the shape memory alloy was in a martensite state. The method further comprises heating the fastener above an austenite start transition temperature, such that the fastener initiates free expansion from the second shape back to the first shape and establishes physical contact with the surface of the first hole and the second hole and continuing to heat the fastener such that first structure and the second structure proximate the holes and the fastener undergo plastic deformation.
