Définition :
Résistance d'un corps à l'enlèvement de matière par les processus d'usure, exprimée comme l'inverse du taux d'usure.
Note :
La résistance à l'usure est fonction des conditions du processus d'usure qui doivent toujours être soigneusement spécifiées. Le taux relatif d'usure, parfois employé, utilise des unités arbitraires.

Date :Définition
A term used in reference to those metals which on account of their inherent properties or because of special treatment have surfaces which resist to a considerable degree of abrasive action during service.
Note :
High-carbon cast steels and certain alloy steels (e.g. manganese alloy steel) are usually regarded as "wear-resistant"; wear resistance can be improved by heat-treatment such as martempering, austempering and by surface treatments such as flame and induction hardening, carburising and nitriding; other methods are available such as hard chromium plating and the processes used for weld depositing hard facing materials; since "wear" is usually employed in a very general sense, corrosion- and heat-resisting materials are sometimes included under the term wear-resisting materials.
Termes :
- wear resistance
- resistance to wear
- resistance against wear
