<\/p>\nAl\u00fcminyum ve al\u00fcminyum ala\u015f\u0131mlar\u0131 i\u00e7in, ak\u0131 kullan\u0131larak gaz giderme ve c\u00fcrufla\u015ft\u0131rma \u00f6nemli bir y\u00f6ntemdir. Ak\u0131 ile ar\u0131tma i\u015flemi uygulan\u0131rken, eriyik i\u00e7inde \u00e7ok say\u0131da da\u011f\u0131n\u0131k ve ince ak\u0131 damlac\u0131klar\u0131 olu\u015fur. \u00c7\u00f6z\u00fcnme dengesi yasas\u0131na g\u00f6re, eriyikteki atomik hidrojen, ak\u0131 damlac\u0131klar\u0131n\u0131n dif\u00fczyonu nedeniyle s\u0131v\u0131 y\u00fczeye ta\u015f\u0131n\u0131r ve b\u00f6ylece eriyikteki hidrojen i\u00e7eri\u011fi azal\u0131r.<\/p>\n
D\u00f6k\u00fcm s\u0131ras\u0131nda erimi\u015f metal b\u00fcy\u00fck miktarda gaz i\u00e7erir ve kat\u0131la\u015farak k\u00fcl\u00e7ede p\u00fcr\u00fczs\u00fcz i\u00e7 y\u00fczeyli yuvarlak bir delik olu\u015fturur. G\u00f6zeneklerin ba\u015fl\u0131ca nedenleri \u015funlard\u0131r: kullan\u0131lan hammaddelerin nemli olmas\u0131 ve f\u0131r\u0131n ile aletlerin tam olarak kurutulmam\u0131\u015f olmas\u0131. Eri\u015fme s\u0131cakl\u0131\u011f\u0131 y\u00fcksek, kaplama yetersiz, y\u00fcksek s\u0131cakl\u0131kta kalma s\u00fcresi uzun ve eriyik b\u00fcy\u00fck miktarda gaz emer. Gaz giderme ve ar\u0131tma i\u015flemi tam olarak yap\u0131lmazsa, kristalle\u015fme s\u00fcrecinde gaz eriyikten d\u0131\u015far\u0131 \u00e7\u0131kamaz ve g\u00f6zenekler olu\u015fur. Bas\u0131n\u00e7l\u0131 i\u015fleme sonras\u0131nda g\u00f6zenekler s\u0131k\u0131\u015ft\u0131r\u0131labilir, ancak bu i\u015flem kolay de\u011fildir ve i\u015flenmi\u015f ve \u0131s\u0131l i\u015flem g\u00f6rm\u00fc\u015f \u00fcr\u00fcnlerde kabuklanma ve kabarc\u0131klar gibi kusurlara yol a\u00e7mas\u0131 kolayd\u0131r; ayr\u0131ca metalin \u00e7e\u015fitli \u00f6zellikleri \u00f6nemli \u00f6l\u00e7\u00fcde azal\u0131r.<\/p>\n
Ar\u0131tma i\u00e7in kullan\u0131lan ak\u0131, d\u00fc\u015f\u00fck erime noktas\u0131na, d\u00fc\u015f\u00fck yo\u011funlu\u011fa, d\u00fc\u015f\u00fck y\u00fczey gerilimine, y\u00fcksek aktiviteye ve oksitler i\u00e7in g\u00fc\u00e7l\u00fc adsorpsiyon kapasitesine sahip bir tuzdur. Kullan\u0131m s\u0131ras\u0131nda, demir kafese k\u00fc\u00e7\u00fck bir par\u00e7a ak\u0131 koyun, ard\u0131ndan bunu kar\u0131\u015ft\u0131rma f\u0131r\u0131n\u0131n\u0131n taban\u0131na yerle\u015ftirin ve ileri geri kar\u0131\u015ft\u0131r\u0131n. Ak\u0131 i\u015flemi tamamland\u0131ktan sonra demir kafesi \u00e7\u0131kar\u0131n ve 5-10 dakika bekletin. Y\u00fczeydeki c\u00fcrufu temizleyin ve ard\u0131ndan d\u00f6k\u00fcm i\u015flemini ger\u00e7ekle\u015ftirin.<\/p>\n
