Abstract: A sensor probe device for monitoring atmosphere within a chamber. The device includes a housing that extends through a wall of the chamber being monitored, and a tubular sleeve that is movably captured within the housing. The sleeve includes an open end for receiving a sensor probe, and a closed end having a plurality of radially spaced apertures that extend through the sleeve wall. The apertures provide an open ribbed portion that exposes the enclosed sensor probe to chamber atmosphere when the sleeve portion is inserted into the chamber. A drive mechanism is attached to either extend the open ribbed portion of the sleeve outward from its shielded position within the housing to an extended position within the chamber, or retract the sleeve portion from the chamber back into its shielded position within the housing.

The method includes the steps of treating a product having a coating containing both zinc and aluminum, such as galvanized strip, or up to 70% by weight, aluminum, balance essentially zinc coated strip, with an aqueous alkaline solution for a sufficient time to form a zinc-rich surface on said product, which surface is reactive with a blackening bath containing Ni and Sb, and subjecting such treated product to such blackening bath to form said thin, uniform, light-absorptive surface layer on said product. The light-absorptive surface layer has a thickness of at least 80 nm, preferably between about 100-400 nm, and an absorptance greater than about 95% over the solar radiation spectrum.

Abstract: A coated ferrous article with improved properties, e.g., improved overall corrosion resistance and good appearance. The article has a ferrous substrate and a ductile, adherent, corrosion resistant alloy coating metallurgically bonded to the substrate. The alloy coating has a thin intermetallic alloy layer intermediate the substrate and an alloy overlay. The alloy overlay consists essentially of, by weight, magnesium from 3% to 20%, silicon from 3% to 15%, balance aluminum and zinc, where the ##EQU1## is between 1 and 1.5. The metallurgical structure of the overlay is a mixture of (1) cored aluminum-rich dendrites having dendrite arm spacings (DAS) of less than 10.mu., (2) zinc-rich interdendritic regions, and (3) intermetallic phases of zinc, aluminum, magnesium and silicon. The article may be produced by hot dip coating a ferrous substrate in a molten metal bath of the above composition.

Abstract: This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base. Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention. The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base. For a plain content steel base, a phosphorus content of at least 0.020% by weight, preferably at least 0.030%, and more preferably at least 0.039% was found sufficient to render such zinc-alloy coated ferrous base resistant to embrittlement by zinc.
