Abstract
Mechanical systems having anti-stick mediums applied thereto are provided. In one aspect, exhaust gas recirculation (EGR) valve systems having anti-stick mediums applied thereto are also provided. The anti-stick medium can be applied to any contacting surface, such as but not limited to the valve surface and/or the valve seat surface. The anti-stick medium is intended to prevent the valve surface and the valve seat surface sticking or bonding together, especially with respect to the operation of cooled or cold side EGR systems. If any materials should stick to the anti-stick medium, a portion of the anti-stick medium will break away from the surface, allowing the surface and/or component to function normally. The anti-stick medium can include, without limitation, boron nitride coatings, boron nitride aerosols, boron nitride greases, thin dense chrome platings, perfluoroalkoxy, and combinations thereof.
