  • Patent number: 7989077
    Abstract: A coated steel product comprises a metallic strip material which has a coating comprising an electrically insulating layer doped with sodium. The thermal expansion coefficient of said metallic strip material is less than 12×10?6 K?1 in the temperature range 0-600° C. Said product may be coated with an electrically conducting layer of molybdenum. The coated steel product is useful as a substrate for flexible Cu(In,Ga)Se2 (CIGS) solar cells.
    Type: Grant

  • Patent number: 6977016
    Abstract: A method has been developed for surface modifications of high temperature resistant alloys, such as FeCrAl alloys, in order to increase their resistance to corrosion at high temperatures. Coating it with a Ca-containing compound before heat-treating builds a continuous uniform and adherent layer on the surface of the alloy, that the aluminum depletion of the FeCrAl alloy is reduced under cyclic thermal stress. By this surface modification the resistance to high temperature corrosion of the FeCrAl alloy and its lifetime are significantly increased.

  • Patent number: 6627007
    Abstract: A method has been developed for surface modifications of high temperature resistant alloys, such as FeCrAl alloys, in order to increase their resistance to corrosion at high temperatures. Coating it with a Ca-containing compound before heat-treating builds a continuos uniform and adherent layer on the surface of the alloy, that the aluminum depletion of the FeCrAl alloy is reduced under cyclic thermal stress. By this surface modification the resistance to high temperature corrosion of the FeCrAl alloy and its lifetime are significantly increased.
