  • Patent number: 9816613
    Abstract: A sliding element, such as a piston ring, including a substrate, base coating, and relatively thin sliding coating is provided. The base coating is typically applied to a running surface of the substrate by PVD, CVD, galvanic deposition, electrodeposition, or a thermal spray process. The sliding coating includes a polymer matrix and hard particles disposed throughout the matrix. The sliding coating is applied to the base coating when the base coating is still in its as-applied condition and has a surface roughness of at least 4.0 ?m. During use of the sliding element, the thin sliding coating acts as a sacrificial run-in layer. In addition, as the polymer matrix of the sliding coating wears away, the hard particles polish the rough surface of the base coating. Thus, polishing or lapping of the as-applied base coating prior to use of the sliding element is not required.
