| description | The present invention provides an improved ultrasonic finishing process and apparatus for finishing a metal article. The method includes cavitationally eroding the metal article to form pits in its external surface. The metal article is also corroded with a corrosion chemical to corrode the pitted metallic surface. In this manner, substantially homogeneously distributed micro-pits can be formed about the article to create a desired matte finish, as well as a surface that is amenable for sealing. In a preferred embodiment, the corrosion chemical is part of a finishing bath containing an alkaline solution that is ultrasonically cavitated for eroding the metal article such as those composed of aluminium.
L'invention concerne un procédé et un système permettant de réaliser des opérations de finition améliorée qui, selon une variante, portent sur un article métallique. Le procédé consiste en une érosion par cavitation visant à former des creux sur la surface externe de l'article métallique, lequel subit également une corrosion chimique visant à attaquer la surface métallique sur laquelle des creux ont été formés. On parvient à réaliser des micro-creux à répartition sensiblement homogène sur l'article, de manière à donner le fini mat souhaité, sachant que, par ailleurs, la surface ainsi traitée se prête au scellage. En mode de réalisation préféré, la corrosion chimique fait partie intégrante d'un traitement en bain de finition à cavitation aux ultrasons qui entraîne une érosion de l'article métallique. |
