  • 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%.

Using the advanced spraying methods the composite layer can be created by co-spraying the galvanic metal and the nonconductive material onto the surface of the galvanic coating. Optionally, an outer coat of insulating material can be applied to provide further protection to the surface.

    Abstract: Disclosed is a refrigeration circuit-forming member which has a metal surface and is used for a refrigeration circuit in which HFO-1234yf that is a refrigerant configured of molecules having a double bond is used. The metal surface, which comes into contact with the HFO-1234yf, is covered with a coating layer that is not reactive with the HFO-1234yf within the range of temperature at which the HFO-1234yf is used. The coating layer is formed of any of a coating film that is firmly fixed to the metal surface, a coating layer that is formed by adhesion of a specific component added into the lubricant oil, and a coating layer that is formed by modification of the metal surface layer itself that forms the metal surface. Consequently, the chemical instability that is caused when the refrigerant HFO-1234yf comes into contact with the metal can be eliminated.
