摘要： A cause estimation device includes: an acquisition unit that acquires a measurement value of a target apparatus; a likelihood calculation unit that calculates, in a case where it is assumed that events occur due to a common cause, a likelihood of an occurrence of each of the events based on the measurement value; a table storage unit that stores a cause table in which a cause of occurrence of the event and a frequency of the cause of occurrence are associated with each other for each of the plurality of events; and an estimation unit that rewrites the frequency registered in the cause table into a frequency in the case where it is assumed that the plurality of events occur due to the common cause, and estimates the cause of occurrence based on the rewritten cause table and the likelihood.

摘要： A thermal barrier coating film includes a bond coat layer that is a metallic bond layer formed on a base material; a topcoat layer that is a ceramic-containing layer formed on the bond coat layer; and at least one of a protective layer and a protective substance. The protective layer is formed on the topcoat layer and mainly contains SrSO4. The protective substance is provided in a plurality of void spaces included in the topcoat layer and mainly contains SrSO4.

摘要： A thermal barrier coating includes a bond coat layer deposited on a substrate, and a ceramic layer deposited on the bond coat layer. The ceramic layer includes a first layer having a porosity of 10% or more and 15% or less, and a second layer having a porosity of 0.5% or more and 9.0% or less and deposited on the first layer.

摘要： A thermal barrier coating includes a highly porous layer and a dense layer. The highly porous layer is formed on a heat-resistant base, is made of ceramic, has pores, has a layer thickness of equal to or larger than 0.3 mm and equal to or smaller than 1.0 mm, and has a pore ratio of equal to or higher than 1 vol % and equal to or lower than 30 vol %. The dense layer is formed on the highly porous layer, is made of ceramic, has a pore ratio of equal to or lower than 0.9 vol % that is equal to or lower than the pore ratio of the highly porous layer, and has a layer thickness of equal to or smaller than 0.05 mm.
