Ingxube ye-Kovar 4j29

I-4J29 alloy yaziwa nangokuthi i-Kovar alloy. Ingxubevange ine-coefficient yokwandisa eqondile efana naleyo yengilazi eqinile ye-borosilicate ku-20 ~ 450℃, iphoyinti eliphezulu le-Curie kanye nokuzinza okuhle kwe-microstructure yezinga lokushisa eliphansi. Ifilimu ye-oxide ye-alloy iminyene futhi ingangenwa kahle ngengilazi. Futhi ayisebenzisani ne-mercury, ilungele ukusetshenziswa entweni equkethe ukukhishwa kwe-mercury. Kuyinto eyinhloko yokuvala impahla yesakhiwo se-vacuum kagesi. Isetshenziselwa ukwenza i-Fe-Ni-Co alloy strip, ibha, ipuleti nepayipi elinengilazi eqinile/okufakwa uphawu ngeceramic, esetshenziswa kakhulu ku-vacuum electronics, amandla kagesi nezinye izimboni.
4J29 Uhlolojikelele lwesicelo kanye nezidingo ezikhethekile
Ingxubevange iyingxubevange ejwayelekile yengilazi eqinile ye-Fe-Ni-Co evame ukusetshenziswa emhlabeni. Sekuyisikhathi eside isetshenziswa imboni yezindiza futhi ukusebenza kwayo kuzinzile. Isetshenziselwa kakhulu ukuvalwa kwengilazi yezingxenye zikagesi ze-vacuum ezifana ne-emission tube, i-oscillation tube, i-ignition tube, i-magnetron, i-transistor, ipulaki elivala uphawu, ukudluliselwa, umugqa wokuhola ohlanganisiwe wesekethe, i-chassis, igobolondo, ubakaki, njll. i-coefficient yokwandisa ingilazi ekhethiwe kanye ne-alloy kufanele ifaniswe. Ukuzinza kwezicubu zokushisa okuphansi kuhlolwa ngokuqinile ngokuya ngokushisa kokusetshenziswa. Ukwelashwa okufanele kokushisa kufanele kwenziwe enqubweni yokucubungula ukuze kuqinisekiswe ukuthi impahla inomsebenzi omuhle wokudweba okujulile. Uma usebenzisa izinto zokubumba, ukuqina kwayo komoya kufanele kubhekwe ngokuqinile.
Ingxubevange ye-covar ngenxa yokuqukethwe kwe-cobalt, umkhiqizo awukwazi ukumelana nokugqoka.
Ingavalwa kalula ngengilazi yeqembu le-molybdenum, futhi indawo ejwayelekile yendawo yokusebenza idinga ukufakwa kwegolide.
4J29 Ukuhleleka:
I-alloy inezindawo ezinhle zokusebenza ezibandayo nezishisayo, futhi ingenziwa ibe yizimo ezihlukahlukene eziyinkimbinkimbi zezingxenye. Kodwa-ke, ukushisa endaweni enesulfure kufanele kugwenywe. Ekugoqeni okubandayo, lapho izinga elibandayo le-strip lingaphezu kuka-70%, i-anisotropy yepulasitiki izongeniswa ngemva kokuhushulwa. Uma izinga lobunzima obubandayo liku-10% ~ 15%, okusanhlamvu kuzokhula ngokushesha ngemva kokudonsa, futhi i-anisotropy yepulasitiki ye-alloy nayo izokhiqizwa. I-anisotropy yepulasitiki incane uma izinga lokugcina lingama-60% ~ 65% kanti usayizi wokusanhlamvu u-7 ~ 8.5.
4J29 Izakhiwo zokushisela:
I-alloy ingafakwa ngethusi, insimbi, i-nickel nezinye izinsimbi nge-brazing, i-fusion welding, i-resistance welding, njll. Uma okuqukethwe kwe-zirconium ku-alloy kungaphezu kuka-0.06%, kuzothinta izinga lokushisela lepuleti futhi i-weld crack. Ngaphambi kokuba i-alloy ivalwe ngengilazi, kufanele ihlanzwe, ilandelwe ukushisa okuphezulu okumanzi kwe-hydrogen ukwelashwa kanye nokwelashwa kwangaphambili kwe-oxidation.
Inqubo yokwelapha ye-4J29: Ukwelashwa okungaphezulu kungaba ukuqhunyiswa kwesihlabathi, ukupholisha, ukucotshwa.
Ngemuva kokuthi izingxenye zivalwe ngengilazi, ifilimu ye-oxide eyenziwe ngesikhathi sokubekwa uphawu kufanele isuswe ukuze kube lula ukushisela. Izingxenye zingashiswa zibe cishe ku-70 ℃ kusixazululo esinamanzi esingu-10% hydrochloric acid +10% nitric acid, futhi zifakwe emanzini anosawoti 2 ~ 5min.
I-alloy inokusebenza okuhle kwe-electroplating, futhi indawo engaphezulu ingaba yigolide, isiliva, i-nickel, i-chromium nezinye izinsimbi. Ukuze kube lula ukushisela noma ukubopha ngokucindezela okushisayo phakathi kwezingxenye, kuvame ukumbozwa ngethusi, nickel, igolide nethini. Ukuze kuthuthukiswe ukuqhutshwa kwe-high frequency current futhi kuncishiswe ukumelana nokuxhumana ukuze kuqinisekiswe izici ezivamile zokukhishwa kwe-cathode, igolide nesiliva kuvame ukugcwaliswa. Ukuze kuthuthukiswe ukumelana nokugqwala kwedivayisi, i-nickel noma igolide kungenziwa kucwecwe.
4J29 Ukusika nokugaya ukusebenza:
Izici zokusika ze-alloy zifana nalezo ze-austenitic stainless steel. Ukucubungula kusetshenziswa insimbi yesivinini esikhulu noma ithuluzi le-carbide, ukucutshungulwa kokusika isivinini esiphansi. I-coolant ingasetshenziswa lapho usika. I-alloy inomsebenzi omuhle wokugaya.
