  • Patent number: 5043137
    Abstract: This invention relates to a method and a device to produce a coating from metal powder metallurgically bonded to a metallic part, said metal powder being compacted over the surface of said metallic part to form the coating using cold isostatic pressing, then coupling an open metallic container to the coating leaving a space between said open metallic container and said coating, completely filling the space between the metallic container and the coating with a ceramic material and sealing, so that the ceramic material exerts pressure due to the thermal expansion over the coating during the heating in a sintering furnace in order to get a metallurgical bond between the metallic part and the coating and simultaneously sintering the coating to achieve the desirable the desirable thickness and the required properties.
