Abstract: A coating process employing coating techniques which allow an end-user to coat steel, rather than relying on a specialized location or supplier, is provided. The techniques produce a coating having high temperature oxidation resistance, greater corrosion resistance, and added surface lubricity to minimize die wear during a stamping process. The techniques also allow configurability with surface textures and allow thickness control. In addition, selective coating of a part or product, for example, around a weld area, and the addition of componentry, for example sensors, with the sensors being employed to monitor the coating, is possible. The coating includes a top functional layer including least one of Al, Ni, Fe, Si, B, Mg, Zn, Cr, h-BN, and Mo, and an interfacial layer with intermetallics formed therein. The interfacial layer can consist of at least one intermetallic, or the interfacial layer can include a mixture of the intermetallic(s) and steel.

Abstract: A protective surface treatment in the form of a coating for steel or another metal or metal alloy capable of providing oxidation resistance in an inert gas furnace or air-containing furnace is provided. The coating is formed by a solution including at least one flux agent, such as boric acid, and at least one binder, such as polyvinylpyrrolidone (PVP), polyvinylpyrrolidone/vinyl acetate (PVP/VA), hydrooxypropylcellulose (HPC), ethylcellulose, and/or acrylics. The solution also includes at least one solvent, such as methanol or ethanol and can include various additives. The finished coating includes iron borate and provides a glassy surface.

Abstract: A container for fuel cells is made from an iron aluminide alloy. The container alloy preferably includes from about 13 to about 22 weight percent Al, from about 2 to about 8 weight percent Cr, from about 0.1 to about 4 weight percent M selected from Zr and Hf, from about 0.005 to about 0.5 weight percent B or from about 0.001 to about 1 weight percent C, and the balance Fe and incidental impurities. The iron aluminide container alloy is extremely resistant to corrosion and metal loss when exposed to dual reducing and oxidizing atmospheres at elevated temperatures. The alloy is particularly useful for containment vessels for solid oxide fuel cells, as a replacement for stainless steel alloys which are currently used.
