  • Patent number: 10844478
    Abstract: The present invention provides a Cr-rich cathodic arc coating, an article in turbine blade coated with the chromizing over cathodic arc coating, and a method to produce the coating thereof. The Cr-rich cathodic arc coating in the present invention comprises a cathodic arc coating and a diffusion coating deposited atop the cathodic arc coating to enforce hot corrosion resistance. The hardware coated with the chromizing over cathodic arc coating in the present invention is reinforced with superior-hot corrosion resistance. The present invention further provides a novel method for producing the chromizing over cathodic arc coating by re-sequencing coating deposition order. The method in the present invention is efficient and cost-reducing by eliminating some operations, e.g., DHT and peening, between the cathodic arc coating and the diffusion coating. The hot corrosion resistance in the present invention results from the high Cr content in the surface of the coating.

    Abstract: A bond coating having high corrosion and oxidation resistance and good compatibility with a thermal barrier coating is disclosed. The bond coating may be an optimized NiCrAlY material with additional materials that eliminates the presence of beta phase for oxidation by replacing the beta phase with a gamma/gamma prime system. The bond coating may also decrease the presence of phases that are detrimental to the mechanical and oxidation properties of the system, such as the sigma and BCC chromium phases. The bond coating may also have a gamma/gamma prime transition temperature that is about 400 degrees Celsius higher than conventional bond coatings, which enables local stresses to be reduced.

  • Patent number: 8586194
    Abstract: Magnetic materials and methods exhibit large magnetic-field-induced deformation/strain (MFIS) through the magnetic-field-induced motion of crystallographic interfaces. The preferred materials are porous, polycrystalline composite structures of nodes connected by struts wherein the struts may be monocrystalline or polycrystalline. The materials are preferably made from magnetic shape memory alloy, including polycrystalline Ni—Mn—Ga, formed into an open-pore foam, for example, by space-holder technique. Removal of constraints that interfere with MFIS has been accomplished by introducing pores with sizes similar to grains, resulting in MFIS values of 0.12% in polycrystalline Ni—Mn—Ga foams, close to the best commercial magnetostrictive materials. Further removal of constraints has been accomplished by introducing pores smaller than the grain size, dramatically increasing MFIS to 2.0-8.7%.
