Heating Article Comprising a Microstructured Heat-Stable Coating and Method of Manufacturing Such an Article

摘要

Provided is a heating article comprising a substrate having two opposite surfaces, a heat-stable coating comprising at least one base layer comprising at least one heat-stable binder, said base layer being arranged on one of the surfaces of the substrate, and one microstructured surface layer comprising a heat-stable binder of the same chemical nature as that of the base layer. The microstructured layer partly or fully covers the base layer and is sintered integrally to it. The microstructured surface layer has a relief with patterns comprised of local variations in its surface level, said relief having a regularity in average pitch Ar with a variation SAr which is not more than 10% higher or lower than the value of said average pitch Ar. A method of manufacturing such an article is also provided.

1. A heating article comprising:
a substrate having two opposite sides, a heat-stable coating comprising: at least a base layer comprising at least one heat-stable binder, said base layer being arranged on one of the sides of the substrate, and a microstructured surface layer comprising a heat-stable binder of the same chemical nature as that of the base layer, said microstructured layer partially or completely covering said base layer and being sintered integrally with the latter, said microstructured surface layer having a relief with patterns constituted by local variations in its surface level, said relief having a regularity in average pitch Ar with a variation SAr not more than 10% of the value said average pitch Ar, on either side of this value Ar.
