Multilayer articles comprising a release surface and methods thereof

A release surface coated substrate made by a process comprising:

• delivering abrasive particles comprising a silicon compound from at least one gaseous fluid jet in the absence of liquids to a metal surface to embed the metal surface with the silicon compound to form a silicon compound layer, wherein the abrasive particles have a particle size ranging from 0.1 to 10000 microns and a Mohs hardness of from 3 to 10;
• coating the silicon compound layer with a coating comprising a coupling agent to form a coupling agent layer;
• coating the coupling agent layer with an aqueous fluoropolymer dispersion to form a fluoropolymer layer and thereby forming a multilayered article, wherein the aqueous fluoropolymer dispersion comprises a fluorinated polymer, wherein the fluorinated polymer comprises at least one of (a) a partially fluorinated polymer capable of forming a carbon-carbon double bond, (b) a functionalized fluorinated polymer, and (c) combinations thereof;
• and
• sintering the multilayered article to form the release surface coated substrate.
