    摘要: The present invention relates to a cylinder sleeve (10) for internal combustion engines, more concretely to a cylinder sleeve (10) inserted by casting into an engine block (8), wherein the circumferential outer surface (2) is provided with a coating (5) capable of providing adhesion between the cylinder sleeve (10) and the engine block (8), inhibiting the formation of empty spaces (4) and providing excellent heat exchange for the engine block (8). The coating (5) has the particularity of being constituted by a nickel- phosphorus (NiP) alloy with a varying melting temperature as a function of the phosphorus contents, which enable a sleeve (10) coated with such an alloy to be inserted by high pressure die cast or low pressure die cast or by gravity.

    摘要: A multilayer dielectric film including a first dielectric layer made from a material having a first breakdown field strength and a second dielectric layer disposed on the first dielectric layer made from a material having a different breakdown filed strength. A multilayer film including first and second electrically conductive layers separated by at least first and second dielectric layers is also disclosed. The first dielectric layer is disposed on the first electrically conductive layer, and the second dielectric layer is disposed on the first dielectric layer. The first electrically conductive layer can have at least one of an average surface roughness of at least ten nanometers, a thickness of at least ten micrometers, or an average visible light transmission of up to ten percent. The first dielectric layer may be a polymer and typically has a lower dielectric constant than the second dielectric layer, which may be ceramic.

    摘要: The invention relates to a method for coating piston rings (10) for internal combustion engines, wherein at least the bearing surface of the piston ring is provided with an anti-abrasion and anti-corrosion coating (12) by means of a PVD or electroplating process. According to said method, the anti-abrasion and anti-corrosion coating is prevented from flaking or cracking caused by strain occurring on the piston ring during the operation of the motor by means of the following steps: a) coating parameters are set; b) an uncoated piston ring (18) is pre-stressed in order to obtain a predetermined diameter (06) thereof or opening width (10); an ion coating process is carried out using coating parameters according to step a); the internal stress of the anti-abrasion or anti-corrosion coating (12) is measured in state (b); e) a new, uncoated piston ring (10) is subjected to tensile pre-stressing or compressive strain according to the measured internal tension of the coating; and f) the piston ring is coated (10) according to the coating parameters according to step a).
