Abstract

Procédé et composition pour former une couche carburée sur la surface d'un objet en alliage de fer. Le bain de traitement comprend, outre de l'acide borique ou du borate, un oxyde d'un élément du groupe Va ou un oxyde de chrome et un ou plusieurs métaux ou alliages d'éléments du groupe Va ou du chrome, pourvu que les éléments sous forme métallique soient autres que ceux sous forme d'oxyde. Industries automobiles.A method and composition for forming a carburized layer on the surface of an iron alloy article. The treatment bath comprises, in addition to boric acid or borate, an oxide of an element of group Va or an oxide of chromium and one or more metals or alloys of elements of group Va or chromium, provided that the elements in metallic form are other than those in oxide form. Automotive industries.
