Abstract: PROBLEM TO BE SOLVED: To provide a superalloy article having a thermal barrier coating film. SOLUTION: The article comprises a superalloy substrate, an adherent alumina layer on the substrate, and a ceramic, thermally insulating layer on the alumina layer. The ceramic layer has an overall thickness and comprises relatively strain tolerant columnar grain ceramic on the alumina layer and relatively more thermally insulating ceramic on the columnar grain ceramic. The alumina layer may be formed using an alumina forming layer such as an overlay or aluminide bond coat, or the superalloy may be constituted of a material capable of forming an alumina layer. The ceramic layers may be formed of a stabilized zirconia or other suitable material and may have the same or different compositions. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To enhance heat insulating characteristics by correcting the intrinsic heat insulating characteristics of a ceramic coating for heat resistance, that is, the density thereof. SOLUTION: In a method for manufacturing the layered ceramic coating wherein some layers are porous, a heat protecting barrier wall is cyclycally inserted in the gap between a heat source and an evaporation source or external heater under different temperature conditions to be coated with different layers. As coating advances, some layers have a zone I structure and some layers have a zone II structure. In order to increase the porosity of the layers having the zone I structure, heat treatment can be also applied.

Abstract: PROBLEM TO BE SOLVED: To reduce thermal conductivity and improve wear resistance by making at least one layer of a layer like ceramic coating applied on a base body of high density and making at least one of other layer low density. SOLUTION: At least one layer of a porous ceramic layer coated on a base body is a porous layer having at least a volume porosity rate of about 20%, and one of other layer is substantially a non porosity layer having a volume porosity rate of about 5%. The ceramic material on a base body is obtained so that plural ceramic layers are vapor deposited and heat treated under conditions consequentially that at least one layer has a micro structure of a band region I and at least one of other layer has a micro structure selected from band regions II, III and a group of these combinations. A porous layer preferably includes a layer made of celia for a base material and a layer made of zirconia for a base material.

Abstract: PROBLEM TO BE SOLVED: To obtain a molybdenum disilicide (MoSi2) material which is hardy pasting. SOLUTION: The MoSi2 alloy which is hardly pasting contains Re. When Re is added to the alloy, a thin protecting film is formed which suppresses the decomposition caused by pasting. The amount of Re necessary to eliminate the pasting is 2-50% of Mo+Re based on atomic reference system, preferably 5-40% of total of Mo+Re. A compositional formula explaining the wide range of composition of this invention is (MoaRebXc) (SidZc), wherein a: a+b+c=1, b: d+e=2, c: b=0.02-0.5, d: X is actually to be selected the group consisting of Cr, Ti, Fe, Co, Ni and their mixtures, e: c=0-0.2, f: Z is actually to be selected from the group consisting of B, Ge, Al, Ga, Sn, Sb, Bi and their mixtures, g: d=1.8-2.0, h:e=0-0.2.

Abstract: PROBLEM TO BE SOLVED: To produce a member having improved ceramic thermal barrier coating(TBC). SOLUTION: A member 10 contains a base material 12 of a superalloy and an adhesive alumina layer 16 formed on the surface of the base material. This member furthermore contains a ceramic layer, i.e., a thermal barrier coating 18 applied on the alumina layer 16 and forming columnar crystals. Desirably, the coating 18 is composed of a substantially uniform mixture of two materials, e.g. of yttria and ceria, wherein the content of yttria is controlled to at least about 5 wt.%, and ceria constitutes the rest. For increasing the adhesion of the thermal barrier coating 18, the member 10 may contain an intermediate bond coat 17 of ceramic such as yttria stabilized zirconia or the like.

Abstract: PROBLEM TO BE SOLVED: To improve the heat insulating properties per unit coating density in a member by incorporating gadolinia and zirconia into ceramic coating on the surface of a substrate made of metal and allowing it to have cubic crystals. SOLUTION: On the outside surface of a superalloy substrate 10, heat insulating coating composed of a pyrochlore top coat 20 is formed. This pyrochlore top coat 20 is composed of about 5 to 60 mol% gadolinia, and the balance gadolinia zirconia oxide containing zirconia and has cubic crystals. In the case of use for a turbine engine, the opposite side face 11 of the superalloy substrate 10 is cooled by cooling air, the outside surface 21 (exposed face) of the pyrochlore structural body is exposed to a high temp., plural holes communicating the outside surface 21 with the opposite side face 11 are provided, and the cooling air is allowed to flow from the oposite side face 11 to the outside surface 21. The substrate made of a metal is selected from the groups consisting of steel, superalloys, titanium alloys and copper alloys.
