摘要：
An element with at least one slide surface with a coating for use on an internal combustion engine may include a base of a metallic alloy and at least one inner surface provided with a hard ceramic coating generated by physical vapor deposition. The element may include a porosity with a rate lower than 2 percent by volume, a Vickers hardness ranging from 1500 to 3000HV, and a compressive inner tension lower than 500 MPa.
