Description
Wynalazek dotyczy utwardzania glinu, który dzieki tej obróbce moze byc wyzy¬ skany przy budowie samolotów, zamiast miedzi lub zelaza. Wedlug wynalazku przedmiot z glinu obsypuje sie ze wszyst¬ kich stron mieszanina proszków, zlozona z 50% zelazocyjanku potasu i 50% chlorku amonu, otacza warstwa wodorotlenku wap¬ nia i ogrzewa w naczyniu zamknietym do temperatury powyzej 400°C. Nastepnie go¬ racy przedmiot oziebia sie przez zanurzenie w zawiesinie wodorotlenku wapnia w wo¬ dzie. Wodna zawiesina wodorotlenku wap¬ nia nie powinna byc ciepla. Najlepiej stoso¬ wac ja po ochlodzeniu do temperatury -^5°C. PL
