Abstract

L'invention concerne un procédé d'application d'un revêtement par voie électrochimique, selon lequel un substrat (14) est soumis à l'action d'un champ magnétique (23) pendant le processus de formation de la couche. Cette invention concerne également un dispositif d'application d'un revêtement par voie électrochimique. Selon la présente invention, le champ magnétique (23) est généré au niveau de la surface à enduire (21) du substrat (14) avec une répartition d'intensités de champ H(x) variable localement, des lignes de champ électriques (24) étant ainsi concentrées dans l'électrolyte sur les zones à intensité de champ magnétique élevée. Ainsi, la croissance d'une couche (22) dans ces zones est accrue, ce qui permet de produire, par exemple, un profil ondulé (27) sans étape de traitement ultérieur. En dimensions appropriées, cette surface ondulée réduit avantageusement la résistance à l'écoulement de la surface (27) de la couche, c'est pourquoi un revêtement de ce type convient, par exemple, à des aubes de turbine optimisées du point de vue de l'écoulement.
