摘要： A process for protecting a part made of a hafnium-free nickel-based single-crystal superalloy against corrosion and oxidation includes manufacturing a part made of a hafnium-free nickel-based single-crystal superalloy, depositing successively on the part, a first layer including hafnium, then a mixed layer of stacked layers of an undercoat of an alloy having 10 atomic % or more of aluminum and a second layer including hafnium or a mixed layer of an alloy of aluminum and hafnium, and then a third layer including hafnium, and diffusing and performing an oxidation treatment so as to obtain a hafnium-doped alumina layer.

摘要： A lining structure for a refractory vessel contains a first layer containing refractory material; a second layer, in communication with and parallel to the first layer, containing a metal layer or component; and a third layer, in communication with and parallel to the second layer, containing refractory material. The metal component in the second layer contains filled transverse passages, between the surface of the second layer in contact with the first layer and the surface of the second layer in contact with the third layer, producing support structures to maintain the structural integrity of the refractory vessel in use.

摘要： Certain aspects of the invention provides a transient liquid phase (TLP) bonding structure, including Ni based alloys and a TLP bonded layer formed by pack cementation on the Ni based alloys using a pack composition. In one embodiment, the pack composition includes 57 wt. % of aluminum oxide powder, 30 wt. % of Ti powder, 10 wt. % of Ni-50 wt. % Al alloy powder and 3 wt. % of ammonium chloride powder. The Ni based alloys may be Ni-20 wt. % Cr alloys. In certain embodiments, pack cementation is performed on the Ni based alloys under argon for an hour using the pack composition to form a coating. Then the structure is sonicated in acetone for 2 hours, and then annealed under vacuum at about 1200° C. for 2 days to form the TLP bonding structure, which has a uniform γ′ phase distribution with identical compositions and properties at its bonding regions.

摘要： Methods of forming an environmental barrier coating are disclosed. A method includes disposing a powder-based coating on a substrate, heat-treating the powder-based coating at a temperature greater than 800° C. and less than 1200° C. to form a porous coating that includes surface-connected pores, infiltrating at least some of the surface-connected pores of the porous coating with an infiltrant material to form an infiltrated coating, and sintering the infiltrated coating at a temperature greater than 1200° C. and less than 1500° C. to form the environmental barrier coating on the substrate.

摘要： A method is proposed to attenuate hydrogen diffusion through fusion reactor components via controlled oxidation of prealloyed surfaces. Alloys of zirconium, vanadium, titanium, niobium, tantalum, tungsten, nickel and iron may be protected from hydrogen isotope permeation by using vanadium as an intermediate layer and either chromium, nickel-chromium, silicon or aluminum as the oxide forming component. This method may also be used to prevent hydrogen embrittlement of metals from external hydrogen environments and is applicable to the majority of alloy systems exhibiting hydrogen embrittlement phenomena.

摘要： A method for forming a two-layered carbide surface on a ferrous-alloy article containing at least 0.2 percent by weight of carbon. The formation of such a surface is effected by plating the ferrous alloy article with chromium, to form a chromium layer thereon, and heating the thus-plated article in contact with an element of Group Va and/or chromium (a) to diffuse carbon from the ferrous-alloy article into the chromium layer and convert the chromium layer to an intermediate chromium-carbide layer and (b) thereafter to combine carbon in the intermediate chromium-carbide layer with the element (of Group Va or chromium) and thus form a Group-Va-element-carbide layer and/or another chromium-carbide layer on the intermediate chromium-carbide layer.
