<\/p>\nMetaller i\u00e7in \u00e7evrimi\u00e7i gaz giderme sisteminin \u00e7al\u0131\u015fma prensibi, al\u00fcminyumdaki hidrojenin \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011f\u00fcn\u00fcn, al\u00fcminyum eriyikle temas halindeki gaz faz\u0131ndaki hidrojen k\u0131smi bas\u0131nc\u0131 taraf\u0131ndan belirlendi\u011fi esas\u0131na dayan\u0131r. Al\u00fcminyum eriyigindeki hidrojen i\u00e7eri\u011fine kar\u015f\u0131l\u0131k gelen hidrojen k\u0131smi bas\u0131nc\u0131, al\u00fcminyum eriyigiyle temas halindeki ger\u00e7ek gazdaki hidrojen k\u0131smi bas\u0131nc\u0131ndan daha y\u00fcksek oldu\u011funda, al\u00fcminyum eriyigindeki hidrojen gaz faz\u0131na dif\u00fcze olur ve b\u00f6ylece hidrojen giderimi sa\u011flan\u0131r.<\/p>\n

Bu nedenle, al\u00fcminyum eriyikindeki hidrojeni m\u00fcmk\u00fcn oldu\u011funca az inert gaz kullanarak en fazla miktarda gidermek amac\u0131yla, \u00e7evrimi\u00e7i inert gazla hidrojen giderme i\u015flemi a\u015fa\u011f\u0131daki ilkelere uygun olarak ger\u00e7ekle\u015ftirilmelidir:<\/p>\n
\u0130nert gazdaki hidrojen ve oksijen i\u00e7eri\u011fi ne kadar d\u00fc\u015f\u00fckse, o kadar iyidir;
\nErimi\u015f malzemenin i\u00e7ine \u00fcflenen inert gaz\u0131n olu\u015fturdu\u011fu kabarc\u0131klar ne kadar \u00e7ok, ne kadar k\u00fc\u00e7\u00fck ve ne kadar da\u011f\u0131n\u0131k olursa o kadar iyidir;
\nKabarc\u0131klar al\u00fcminyum eriyik i\u00e7inde ne kadar uzun s\u00fcre kal\u0131rsa, o kadar iyi olur.
