Description
<Desc/Clms Page number 1> Dans le brevet prin@ipal n 536.560 du 16 mars 1955, on décrit un procedé pour laproduciton de revêtements ad- hérant à des aciers inoxydables, o'est-à-dire des alliages de fer avec du nickel et/ou du chrome, et à d'autres métaux difficilement attaquables,tels que le nickel,le chrome et leurs alliages,de préférence pour faciliter la déformation sans production de oopeaux,de ces métaux par laminage, étirage et analogue, ce procédé étant caractérisé par le fait que la surface de ces métaux,de préférence après un traitement dé- passivant, connu en soi, est traitée avec une solution acide, qui contient des ions manganèse, des ions oxalate et un composé oxygéné du soufre qui se décompose dans les conditions de tra- vail, avec séparation de l'acide sulfureux et du soufre,cette <Desc/Clms Page number 2> solution ayant un pH de 0,7 à 2,0,de préférence de 1,0 à 1,5 mais ne oontenant pas d'ions halogène. Comme produit d'acidification,en vue de régler et de conserver la valeur du pH,on a préconisé dans le brevet principal l'usage d'acide sulfurique,diacide sulfaminque ou d'acide sulfureux. On a découvert, toutefois. que l'usage d'acide nitrique et/ou d'acide phosphorique,comme produit.d'acidification, présente pour l'application pratique des avantages considé- rables par rapport aux acides proposés à cet effet dans le brevet principal pour la raison que l'accumulation des sulfa- tes complexes trouble le traitement aveo ces acides. Ci-dessous on donne, à titre d'exemples,des solutions convenent à cet effet. EXEMPLE I Carbonate de manganèse 12 g acide nitrique ( à 69%) 24 cm3 acide oxalique 15 g thiosulfate de sodium 5 g eau pour faire un litre @ TEMPLE II carbonate de manganèse 15 g acide oxalique 12 g acide phosphorique (à 75%) 12 g thiosulfate de sodium 5 g eau pour faire un litre A part cela, le procédé correspond à celui indiqué dans le brevet principal.

- RESUME L'invention a pour objet un procédé pour la produotion de revêtements adhérant à de l'acier inoxydable et à d'autres métaux diffiolement attaquables, tels que le niokel,le chrome et leurs alliages, de préférence en vue de faciliter la défor- mation, sans formation de copeaux, de ces métaux par laminage, étirage et analogues, selon le brevet principal n 536.560 du 16 mars 1955,1e présent procédé étant caractérisé par le fait que pour l'acidification on utilise de l'acide nitrique et/ ou de l'acide phosphorique à la place des acides cités dans le brevet principal.L'invention vise plus particulièrement certains modes d' application,ainsi que certains modes de réalisation, du dit procédé; et elle vise plus partioulièrement encore,et ce à titré de produits industriels nouveaux kes métaux traités par ce procédé,les éléments et appareils spéciaux convenant à sa mise en oeuvre ainsi que les articles et objets fabriqués à l'aide @ ces métaux.
