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.

Element comprising at least one sliding surface having a coating for use in an internal combustion engine or a compressor

The present invention relates to an element () that works sliding, of an internal combustion engine and/or a compressor that undergoes friction and receives a coating of chrome nitride having an equiaxial morphology, with low porosity (lower than 1%) and with a crystallographic orientation predominantly (111), maintaining some reticulate in the orientation (200), so as to improve its resistance to wear and its toughness, prolonging the useful life of the element () that works sliding.
