Alloy shine nau'in Fe-Ni-Co mai wuyar gilashin rufewa da aka saba amfani dashi a duniya. An dade ana amfani da shi ta masana'antar sufurin jiragen sama kuma aikinta ya tabbata. An yafi amfani da gilashin sealing na lantarki injin kayan aikin kamar watsi tube, oscillation tube, ƙonewa tube, magnetron, transistor, sealing toshe, gudun ba da sanda, hadedde gubar line, shasi, harsashi, sashi, da dai sauransu A cikin aikace-aikace, da faɗaɗa ƙididdiga na gilashin da aka zaɓa kuma ya kamata a daidaita haɗin gwal. Ana gwada ƙarancin zafin nama mai ƙarfi bisa ga zafin da ake amfani da shi. Ya kamata a gudanar da maganin zafi mai dacewa a cikin tsarin sarrafawa don tabbatar da cewa kayan yana da kyakkyawan zane mai zurfi. Lokacin amfani da kayan ƙirƙira, yakamata a duba tsananin iskansa sosai.
Covar gami saboda abun ciki na cobalt, samfurin yana da ɗan jure lalacewa.
Ana iya rufe shi da sauƙi tare da gilashin ƙungiyar molybdenum, kuma gabaɗaya saman aikin aikin yana buƙatar platin zinari.
4J29 Tsari:
Garin yana da kyawawan kaddarorin sanyi da zafi, kuma ana iya yin su zuwa sassa daban-daban masu rikitarwa. Duk da haka, ya kamata a guji dumama a cikin yanayi mai sulfur. A cikin mirgina sanyi, lokacin da yanayin sanyi na tsiri ya fi 70%, za a jawo anisotropy na filastik bayan an cire shi. Lokacin da yanayin sanyi ya kasance a cikin kewayon 10% ~ 15%, hatsin zai yi girma da sauri bayan an cire shi, kuma za a samar da anisotropy na filastik na gami. Anisotropy filastik shine mafi ƙanƙanta lokacin da ƙimar ƙimar ƙarshe ta kasance 60% ~ 65% kuma girman hatsi shine 7 ~ 8.5.
4J29 Abubuwan walda:
A gami za a iya welded da jan karfe, karfe, nickel da sauran karafa ta brazing, Fusion waldi, juriya waldi, da dai sauransu Lokacin da zirconium abun ciki a cikin gami ya fi 0.06%, shi zai shafi walda ingancin farantin karfe, kuma ko da sa. fashewar walda. Kafin a rufe gami da gilashin, ya kamata a tsaftace shi, sannan a bi da shi tare da babban zafin jiki rigar maganin hydrogen da magani na pre-oxidation.
4J29 Tsarin jiyya na saman: Jiyya na saman yana iya zama fashewar yashi, gogewa, pickling.
Bayan an rufe sassan da gilashin, fim din oxide da aka samar a lokacin rufewa ya kamata a cire shi don walƙiya mai sauƙi. Za a iya dumama sassan zuwa kusan 70 ℃ a cikin wani ruwa mai ruwa 10% hydrochloric acid + 10% nitric acid, kuma pickled na 2 ~ 5mins.
The gami yana da kyau electroplating yi, da kuma surface iya zama zinariya-plated, azurfa, nickel, chromium da sauran karafa. Domin sauƙaƙa walda ko matsi mai zafi tsakanin sassa, ana lulluɓe shi da tagulla, nickel, zinariya da kwano. Don inganta haɓakar haɓakar haɓakar mitar halin yanzu da rage juriya na lamba don tabbatar da halayen fitarwa na cathode na yau da kullun, zinari da azurfa galibi ana yin su. Domin inganta juriya na lalata na'urar, nickel ko zinariya za'a iya sanyawa.
4J29 Yanke da aikin niƙa:
Halayen yankan na gami suna kama da na bakin karfe austenitic. Gudanarwa ta amfani da ƙarfe mai ƙarfi ko kayan aiki na carbide, sarrafa yankan ƙananan sauri. Ana iya amfani da sanyaya lokacin yankan. Alloy yana da kyakkyawan aikin niƙa.
