Abstract
Cette invention se rapporte au domaine de la métallurgie et concerne des revêtements protecteurs ainsi que des procédés d'application de ces revêtements. De manière plus spécifique, cette invention concerne la formation de revêtements durables sur des surfaces de métaux ferreux et non ferreux à l'aide d'un procédé d'oxydation par micro-arc, et peut être utilisée dans le domaine des machines-outils, ainsi que dans les industries chimique et de raffinage de produits pétroliers. Le résultat technique de cette invention consiste en un accroissement de la microdureté et en une meilleure résistance au fissurage de revêtements faits d'une fine couche céramique, ce qui est capital dans la durabilité des céramiques. Cette invention comprend essentiellement les étapes suivantes: un matériau, consistant en une composition métallique qui contient de l'aluminium ainsi que du cuivre dans une quantité de 4 à 10 % et formant une première électrode, est tout d'abord soumis à un traitement. La seconde électrode est faite d'un métal insoluble sur le plan électrolytique. L'électrolyte se présente sous forme d'une solution aqueuse qui contient un alcali dans une concentration de 1 à 6 g/l et du verre soluble dans une concentration de 4 à 6 g/l, et à laquelle on ajoute une poudre se composant à 90 % de SiO2 et à 10 % Al2O3 avec un taux de dispersion de 1 à 10 νm pour une concentration de 0,5 à 2,0 g/l. Le traitement de la surface de la composition métallique contenant de l'aluminium est effectué dans un mode anode-cathode, le rapport entre les intensités à l'anode et à la cathode étant de I = 1,1 à 1,2 pendant une durée de 60 à 180 min. Le revêtement d'une fine couche céramique ainsi obtenu, lequel consiste en une fine couche d'un matériau céramique globulaire et se compose partiellement ou entièrement de grappes de cristaux filamenteux de α-Al2O3 présents dans la matrice cristalline fine de η-Al2O3 et mullite 3 Al2O3 * 2 SiO2, se caractérise par une intensité d'usure I = 10-10 à 10¿-12?, par un coefficient de frottement f = 0,010 à 0,035, par une microdureté H = 16 à 18 GPa et par une charge critique de fissurage P = 2,5 à 3,0 N.
