A sliding material whose surface sliding properties can be altered by shot blasting according to properties required of a sliding part without considerably changing the surface roughness of the sliding material. The sliding material is characterized by comprising a metallic base and a metal deposited mechanically on the sliding surface of the metallic base so as to cover at least 8% of the sliding surface thereof by subjecting metal particles softer than the metallic base and lower in the coefficient of friction than that to shot blasting. L'invention concerne un matériau glissant dont les propriétés de glissement de surface peuvent être modifiées par grenaillage selon les propriétés requises d'un élément glissant sans considérablement modifier la rugosité de surface de l'élément glissant. Le matériau glissant est caractérisé en ce qu'il comprend une base métallique et un métal déposé mécaniquement sur la surface glissante de la base métallique de manière à recouvrir au moins 8 % de la surface glissante en soumettant les particules métalliques moins dures que la base métallique et présentant un coefficient de frottement plus faible à un grenaillage.
