Abstract: The present invention relates, but without limitation, to a system and method for detecting the formation of ice on a surface of a body (1) on which an air stream impinges. Said system comprises: a first and a second temperature detectors (2, 5) with different thermal inertia; and an electro-optic module (10) connected to both detectors (2, 5). Thus, by calculating the different responses of the detectors (2, 5) it is possible to detect the ice formation on a body (1), and more advantageously, the almost instantaneously freezing of supercooled water on a body (1). The present invention can be applied to aircrafts, wind turbines or to electrical power transmission lines.

Abstract: A nickel-based alloy is coated with a silicate based nickel aluminide slurry diffusion coating.

Abstract: At least a part of a burner for a catalytic reactor is coated with a silicate based nickel aluminide slurry diffusion coating.

Abstract: The present invention is designed to improve a method of deposition of coatings upon a metal or alloy substrate. The coating comprises aluminum or aluminide material interdiffused with a transition metal deposited by chemical vapor deposition which utilizes organometallic precursors to facilitate the deposition of the transition metal. The improvement permits better control of the process and permits coating of complex substrates including those with internal passages or holes. In the embodiment involving a first deposition of aluminum or aluminide coating, applicants have achieved deposition thereon of the transition metal. Platinum is the preferred transition metal to be used in the subject method. A product is taught. This product can be a component from a gas turbine engine.
