    摘要： A thermal barrier coating for an underlying metal substrate of articles that operate at, or are exposed to, high temperatures, as well as being exposed to environmental contaminant compositions. This coating comprises an inner layer nearest to the underlying metal substrate comprising a ceramic thermal barrier coating material, as well as an outer layer having an exposed surface and comprising a CMAS-reactive material in an amount up to 100% and sufficient to protect the thermal barrier coating at least partially against CMAS that becomes deposited on the exposed surface, the CMAS-reactive material comprising an alkaline earth aluminate or alkaline earth aluminosilicate where the alkaline earth is selected from barium, strontium and mixtures thereof, and optionally a ceramic thermal barrier coating material. This coating can be used to provide a thermally protected article having a metal substrate and optionally a bond coat layer adjacent to and overlaying the metal substrate. The thermal barrier coating can be prepared by forming the inner layer of the ceramic thermal barrier coating material, followed by depositing the CMAS-reactive material, or codepositing the CMAS-reactive material and the ceramic thermal barrier coating material, to form the outer layer.

    摘要： An article comprising a silicon-containing substrate, an environmental barrier coating (EBC) overlying the substrate, wherein the EBC comprises a higher metal silicate-containing outer barrier layer; and a corrosion resistant alumina/aluminate sealant for the higher metal silicate-containing outer barrier layer. A process is also provided for forming a corrosion resistant alumina/aluminate sealant layer over the higher metal silicate-containing outer barrier layer. Also provided is an alternative process for treating a porous higher metal silicate-containing outer barrier layer with a liquid composition comprising an corrosion resistant alumina/aluminate sealant precursor to infiltrate the porous higher metal silicate-containing outer barrier layer with the alumina/aluminate sealant precursor in an amount sufficient to provide, when converted to the corrosion resistant alumina/aluminate sealant, protection of the environmental barrier coating against environmental attack; and converting the infiltrated alumina/aluminate sealant precursor within the porous higher metal silicate-containing outer barrier layer to the corrosion resistant alumina/aluminate sealant.

    摘要： An article comprising a substrate formed of a silicon-comprising material, such as an article exposed to the hostile thermal environment of a gas turbine engine. The article further comprises an environmental barrier layer formed by chemical vapor deposition and comprising mullite and alumina, and a top coat comprising alumina, stabilized zirconia or stabilized hafnia, wherein the zirconia or hafnia is stabilized with an oxide of a metal selected from the group consisting of magnesium, calcium, scandium, yttrium, and lanthanide metals, and mixtures thereof. The environmental barrier layer is compositionally graded and consists essentially of mullite at an interface of the environmental barrier layer with the substrate, and consists essentially of alumina at an interface of the environmental barrier layer with the top coat, the environmental barrier layer having a decreasing concentration of mullite and an increasing concentration of alumina in a direction away from the substrate. A method for preparing a thermal/environmental barrier coating on a substrate formed of a silicon-comprising material is also disclosed.
