    摘要： The invention relates to a method of treating a liquid gallium or gallium alloy surface for prolonged use as a liquid mirror. The method of the invention comprises the steps of (a) contacting the surface of liquid gallium or gallium alloy with an aqueous solution of a halogenic acid to cause dissolution of any gallium oxide present on the surface, thereby obtaining an oxide-free liquid gallium or gallium alloy surface covered with a layer of the acid solution; (b) adding to the acid solution an aqueous solution of a surfactant present in an amount to form a single bimolecular layer of surfactant at an interface between the liquid gallium or gallium alloy and water; and (c) allowing a uniform passivating oxide layer to gradually form on the oxide-free liquid gallium or gallium alloy surface, the passivating oxide layer having surface irregularities smaller than 40 nm.

    摘要： The present disclosure is directed to methods and compositions for boronizing metal and in particular ferrous surfaces. It has been discovered that if hydrocarbons are processed in metallic equipment which have been previously boronized, that coke formation and deposition which is commonly experienced at high temperatures can be minimized if not totally eliminated. The compositions utilized for this purpose are comprised of boron or boron compounds contained in an organic solvent or carrier together with specific activating materials.

    摘要： A process of boronizing a metal article is described which comprises immersing the selected metal article in a fused bath composed of at least one alkali metal halide or alkaline earth metal halide and a boron slat of the empirical formula MxByFz wherein M is an alkali metal, and the ratio of x:y:z is 1:0.4 to 2.0:0.5 to 2.5 with y being preferably above 1 and z is preferably below 1.5, the fused bath being maintained at a temperature between 1,200* to 1,750* F. for a sufficient duration to impregnate the metal with boron. There is also described novel boron products, their process of manufacture and salt baths containing such boron products. The process produces extremely hard, uniform, adherent and corrosion resistant boride casing on metals such as carbon and alloy steels.
