    Abstract: PROBLEM TO BE SOLVED: To provide a protective coating which has satisfactory heat resistance and long term stability against corrosion and oxidation, and is further suited to mechanical stress forecast in a gas turbine at high temperatures in particular. SOLUTION: The protective coating consists of, by weight, 0.5 to 2% rhenium, 15 to 21% chromium, 9 to 11.5% aluminum, 0.05 to 0.7% yttrium and/or at least one equivalent metal selected from the group consisting of scandium and rare earth elements, and 0 to 1% ruthenium, and the balance cobalt and/or nickel with impurities derived from production. The alloy does not produce precipitates of chromium/rhenium, and exhibits no embrittlement by brittle phases caused by the precipitates. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a protective coating material having both excellent corrosion resistance and mechanical properties and being applicable even to a gas turbine whose inlet temperature is more than 1,200°C for example. SOLUTION: The protective coating is composed of 26-30% nickel, 20-28% chromium, 8-12% aluminum, 0.1-3% reactive elements of at least one kind of rare earth elements and the balance cobalt expressed in terms of weight percent. The material has excellent mechanical properties and also excellent corrosion resistance and exhibits 2.5 times life of a conventional coating on an oxidation test. COPYRIGHT: (C)2004,JPO&NCIPI

    Abstract: Method of coating substrate having at least one opening hole involves covering the hole with a plug of wax, electrochemically depositing at least one coating layer and treating the outer surface of the coating either with an electron beam or laser, to improve the adhesion and homogenize the particles in the upper zone of the coating. To coat a substrate (1), which has at least one opening hole (4), the hole(s) is (are) initially covered by a plug (16) of wax, etc. At least one coating layer (13) is applied electrochemically at a low temperature of at most 250 degreesC and preferably at most 100 degreesC. The outer surface (15) of the coating is treated with an electron beam or a laser and the like, to improve the adhesion and homogenize the particles in the upper zone of the coating, by melting the zone immediately under the upper surface. The coating layer is of a ceramic thermal insulation layer or a metal.
