    摘要: A piston ring, in particular a compression piston ring, includes a running surface, upper and lower flank areas, an inner peripheral area and a joint. The wall thickness of the piston ring is uniform over its periphery and at least the running surface is provided with a PVD coating or a CVD layer in such a manner that the running surface layer has a lesser layer thickness in the peripheral area close to the joint than in the remaining peripheral area of the running surface.

    摘要: A piston ring includes a running surface having a running surface profile, and an upper flank surface and a lower flank surface. At least the running surface is provided with a vapor-deposited layer such that part of the running surface is provided with a removable cover enabling an essentially sharp-edged running edge to be formed between the running surface and at least one of the flank surfaces, once the vapor-deposited layer has been produced and the cover has been removed.

    摘要: The invention relates to a wear protection layer for piston rings in internal combustion engines consisting essentially of chromium carbides, wolfram carbide, chromium and nickel. The wear protection layer is formed from a mixture of powders in which the first powder consists of at least the alloy components chromium carbide, chromium and nickel, in the form of an agglomerated and sintered powder, and which has not been subjected to any secondary heat treatment that would make the powder brittle, such as plasma refinement, the carbides in the powder having an average diameter of essentially not more than 3 μm. A second powder, also in the form of an agglomerated and sintered powder, contains wolfram carbide and is applied to at least one peripheral surface of the piston rings by thermal injection, so that two distinctive coating areas are produced in the wear protection layer. A first area, predominantly rich in chromium, and a second area, mainly rich in wolfram carbide are formed.
