description A heat absorbing coating having a plurality of micro-capsules each being an encapsulant shell and a heat absorbing material within the shell, and a carrier adherable to a substrate and throughout which the micro-capsules are dispersed. The heat absorbing material is preferably a phase change material and can be non-limitedly chosen from the group consisting of polyethylene, polypropylene, polywax, and combinations thereof. Shell material can be a metal such as copper, for example, or a polymer. The carrier can be a sprayable polymer mix which provides significant efficacy in uniform application to a substrate. An inventive substrate structure, such as an aircraft structure for example, has thereon the above-defined coating in an amount sufficient to absorb a sufficient amount of heat from the substrate to substantially inhibit thermal erosion in normal operating environments. Ce revêtement absorbant la chaleur présente une pluralité de microcapsules constituant chacune une enveloppe d'enrobage dans laquelle on a placé un matériau absorbant la chaleur, ainsi qu'un support pouvant adhérer sur un substrat et dans lequel on a dispersé les microcapsules. Le matériau absorbant la chaleur est de préférence un matériau à changement de phase, choisi de manière non limitative dans le groupe constitué par du polyéthylène, du polypropylène, une polycire, et des combinaisons de ces substances. Le matériau de l'enveloppe peut être un métal tel que du cuivre, par exemple, ou un polymère. Le support peut être un mélange polymère hautement efficace que l'on peut vaporiser et qui permet une application uniforme sur un substrat. Une structure de substrat de l'invention, telle qu'une structure d'avion, par exemple, présente le revêtement ci-dessus décrit, déposé en quantité suffisante pour absorber une quantité suffisante de chaleur provenant du substrat, afin d'inhiber sensiblement l'érosion thermique dans des environnements normaux d'utilisation.
