Abstract: front page image
(EN)A treatment method of wearing workpiece for concrete conveyor involves integral quenching of the wearing workpiece (11) and surface softening of non-working surface (11b) of the wearing workpiece after performing integral quenching. The non-working surface (11b) has a softened surface-layer (11d). The hardness of the softened surface-layer (11d) is lower than that of the substrate (11c) arranged below the softened surface-layer (11d). The method satisfies the hardness requirement of the workpiece, improves the toughness of the workpiece, and prolongs the useful time of the workpiece. The present invention further includes a wearing workpiece obtained by the treatment method.
(FR)L'invention concerne un procédé de traitement d'une pièce à travailler d'usure pour transporteur de béton, qui comprend les étapes consistant à : tremper intégralement la pièce à travailler (11) d'usure, et adoucir la surface d'une surface (11b) non active de ladite pièce à travailler après la trempe intégrale. La surface (11b) non active comporte une couche (11d) de surface adoucie. La dureté de la couche (11d) de surface adoucie est inférieure à celle du substrat (11c) se situant sous la couche (11d) de surface adoucie. Le procédé répond au critère de dureté de la pièce à travailler, permet d'améliorer la résistance de la pièce à travailler et de prolonger la durée de vie de celle-ci. L'invention comprend de plus une pièce à travailler d'usure obtenue à l'aide de ce procédé de traitement.
