The base band material that is used for high-temp superconductor coating at present mainly is Ag and Ni.Because Ag self also lacks the technology that obtains strong single component texture polymorph A g base band up to now; And the fusing point of Ag hangs down research and the application that has limited the high-temperature superconductor thick-film technique with the texture poor stability to a certain extent.Handle by rolling and recrystallize and to be easy to obtain strong and pure cubic texture ({ 100}＜001 〉) polycrystalline Ni base band, but because Ni has erosion action to high-temperature superconductor, present method is a preparation Ni base composite baseband, and promptly the evaporation buffer layer prepares the high-temp superconductor coating base band on Ni.This method is deposited by electron beam evaporation method extension Pd (or Pt) and Ag, extension YSZ or CeO then in cubic texture Ni substrate
2Buffer layer.But Pd (or Pt) is very expensive, heterogeneous oxide film (YSZ or CeO
2) the epitaxy difficulty, preparation equipment complexity and technology are difficult to control.Therefore, the optimum combination composite baseband, to reduce cost, simplify technology be that high temperature superconductive wire, band move towards one of key of practicability.
The object of the present invention is to provide a kind of cost is low, technology simply is used for high-temp superconductor coating Ni/NiO texture composite baseband and method for making thereof.
The invention is characterized in: it is a kind of pure and strong cubic texture composite baseband, is made of Ni substrate with cubic texture and cubic texture NiO film that oxidation obtains thereof.Its method for making is: vacuum oven is put in cubic texture Ni substrate, be evacuated to～1Pa, fill purity oxygen then to 1atm and keep flow of oxygen in stove, furnace temperature is risen to 1150～1300 ℃ from room temperature, be incubated 5 minutes～2 hours, promptly obtain cubic texture NiO film.
Feature of the present invention also is: it is a kind of pure and strong rotation cubic texture composite baseband, and it is made of Ni substrate with cubic texture and rotation cubic texture NiO film that oxidation obtains thereof.Its method for making is: vacuum oven is put in cubic texture Ni substrate, be evacuated to～1Pa, fill purity oxygen then to 1atm and keep flow of oxygen in stove, furnace temperature is risen to 1000～1150 ℃ from room temperature, be incubated 5 minutes～2 hours, obtain rotating cubic texture NiO film.
Experimental results show that: it can reach its intended purposes.
In order in conjunction with the embodiments the present invention to be done detailed description below, now as follows present specification used accompanying drawing title and numbering brief introduction:
