Abstract
A method and an apparatus for spraying materials onto a substrate to produce a coating thereon is described which allows very thick layers of complex metal oxides to be produced. The apparatus and method are particularly suitable for producing superconducting coatings.
Claims9
A method of depositing by flame or plasma spraying at atmospheric pressure a layer onto a substrate, the layer having a thickness of at last 5 mm, the coating comprising metal oxides, the method including the steps of:
- depositing an additional noble metal with the coating to increase thermal conductivity of the coating, and
- during deposition of the coating, cooling the substrate so that the solidified coating thereon has a temperature between 25 and 150° C.
