  • Publication number: 20040156724
    Abstract: The invention relates to a thermal barrier coating material for coating a gas turbine member that provides a higher thermal barrier property and a higher peeling resistance. In a first aspect of the invention, a metal binding layer 22 and a porous ZrO2-based ceramic layer 23 are laminated successively on a base material 21, and microcracks that extend in the thickness direction are formed in the ceramic layer 23. After laminating the ceramic layer 23 on the metal binding layer 22 by thermal spraying, etc., microcracks 24 are formed by irradiating with a laser beam a surface of the ceramic layer 23 and thereby heating the surface of the ceramic layer 23 at 1000° C. to 1700° C., while cooling the rear surface of the base material 21. Thus, microcracks 24 are formed by a heating and cooling cycle.

  • Patent number: 4830101
    Abstract: A heat exchanger has special usage such as an evaporator of an automotive air conditioner. This heat exchanger can improve wettability and can reduce a scattering of condensed water. This heat exchanger is treated by a special chemical conversion treatment so that this heat exchanger has two layers of coating on the surface thereof. One of the two layers is a chemical conversion coating formed on the surface of the heat exchanger. The other one is a resin coating formed over the chemical conversion coating. The chemical conversion coating is treated by immersing the heat exchanger into a water solution. The resin coating is also treated by immersing the heat exchanger having the chemical conversion coating into a water solution of organic high polymer material.
