  • Process for coating with ceramic vaporizing materials
    Patent number: 6168833
    Abstract: A process for coating an object with ceramic material vaporized from an ingot of the ceramic material. The process comprises the steps of (a) evaporating the material by melting the surface of the ingot with an intense heat source; and (b) depositing the evaporated material upon the object as a coating. The ingot comprises an unsintered mixture of at least two powder fractions of at least 50% to 90% by volume of a coarse-grained powder and 10% to 50% by volume of a fine-grained powder. The average particle diameter, d50, of the fine-grained powder is at most one third the average particle diameter of the coarse-grained powder.
