Abstract

L'invention porte sur un procédé accroissant la résistance à l'usure de matériaux métalliques consistant: à traiter un matériau métallique par une association d'un champ d'ultrasons, et d'un champs électromagnétique pendant au moins 35. Le champ d'ultrasons présente une puissance de sortie de 20-110 W et une fréquence de 10-30 kHz; le champ magnétique est produit par la bobine (5) à 100-500 spires alimentée par courant alternatif de 30-80A de pic et d'une fréquence de 10-50 Hz; le champ électrique est produit par une bobine d'induction à haute fréquence (4) à 3-10 spires, d'une fréquence de 10-100 kHz et d'une puissance de sortie de 1-8 kW. Le procédé peut réduire les contraintes résiduelles et la transition de phase incomplète et augmenter la résistance à l'usure et la vie de pièces, sans les déformations dues aux traitements thermiques. Il peut être largement utilisé pour traiter divers matériaux métalliques dans les domaines: de l'industrie électrique, de l'usinage, de la mine, de la construction, de l'industrie automobile, etc.
