Title (EN) IMPROVED ALUMINIUM PRODUCTS AND ARTICLES
(FR) PRODUITS ET ARTICLE EN ALUMINIUM AMELIORES
Abstract: front page image
(EN) A downhole tool or other product (P) made essentially of aluminium base material is provided with a hard-faced surface comprised by geometric elements or rough particles (2a) of hard material. Filler material (3) serving to secure the elements/particles to the surface is applied by gas-shielded metal arc welding (e.g. TIG welding) in pulsed mode, so as to fill in the spaces between the elements/particles. In this way, substantial hard-facing can be applied to aluminium articles, where conventional hitherto only steel articles have been susceptible to substantial hard-facing.
(FR) L'invention concerne un outil de fond ou autre produit (P) se composant essentiellement d'une matière de base d'aluminium présentant une surface rechargée formée d'éléments géométriques ou de particules rugueuses (2a) de matière dure. Une matière de charge (3), servant à fixer les éléments/particules à la surface, est appliquée par un soudage à l'arc avec électrode fusible à écran de gaz (notamment le soudage TIG) en mode pulsé de manière à combler les espaces entre les éléments/particules. De cette manière, il est possible de recharger considérablement les articles en aluminium, alors qu'auparavant seuls les articles en acier pouvaient être rechargés.
