Ingxubevange yeKovar 4j29

I-4J29 alloy ikwabizwa ngokuba yi-Kovar alloy. I-alloy ine-coefficient yokwandisa i-linear efana ne-borosilicate hard glass kwi-20 ~ 450 ℃, indawo ephezulu ye-Curie kunye nokuzinza kwe-microstructure ephantsi yobushushu obuphantsi. Ifilimu ye-oxide ye-alloy ixinene kwaye ingangenwa kakuhle ngeglasi. Kwaye ayisebenzi kunye ne-mercury, ilungele ukusetyenziswa kwisixhobo esine-mercury discharge. Yeyona nto iphambili yokutywinwa kwesakhiwo sesixhobo sokufunxa sombane. Isetyenziselwa ukwenza i-Fe-Ni-Co i-alloy strip, ibha, ipleyiti kunye nombhobho kunye neglasi enzima / ukutywinwa kwe-ceramic ehambelanayo, isetyenziswa kakhulu kwi-vacuum electronics, i-electronics yamandla kunye namanye amashishini.
4J29 Ushwankathelo lwesicelo kunye neemfuno ezizodwa
I-alloy yi-alloy ye-Fe-Ni-Co yeglasi eqinileyo yokutywina esetyenziswa ngokubanzi kwihlabathi. Isetyenziswe yifektri ye-aviation ixesha elide kwaye ukusebenza kwayo kuzinzile. Isetyenziselwa ikakhulu ukutywinwa kweglasi yezinto zokucoca zombane ezinje ngetyhubhu ephumayo, ityhubhu ye-oscillation, ityhubhu yokutshisa, imagnetron, itransistor, iplagi yokutywina, ukuhanjiswa, umgca wesekethe odibeneyo, i-chassis, iqokobhe, isibiyeli, njl. i-coefficient yokwandiswa kweglasi ekhethiweyo kunye ne-alloy kufuneka ihambelane. Ukuzinza kwezicubu zobushushu obuphantsi kuvavanywa ngokungqongqo ngokweqondo lokushisa lokusetyenziswa. Unyango olufanelekileyo lobushushu kufuneka lwenziwe kwinkqubo yokucubungula ukuqinisekisa ukuba izinto eziphathekayo zinomsebenzi omhle womzobo onzulu. Xa usebenzisa izinto zokubumba, ukuqina kwayo komoya kufuneka kujongwe ngokungqongqo.
I-covar alloy ngenxa yomxholo we-cobalt, imveliso ayinakunxiba.
Inokutywinwa ngokulula ngeglasi yeqela le-molybdenum, kwaye umphezulu oqhelekileyo we-workpiece ufuna i-plating yegolide.
4J29 ukuQuquzeleka:
I-alloy ineempawu ezintle ezibandayo kunye nokusebenza okushushu, kwaye inokwenziwa kwiimilo ezahlukeneyo eziyinkimbinkimbi zamalungu. Nangona kunjalo, ukufudumeza kwi-atmosphes enesulfure kufuneka kuphetshwe. Xa kuqengqeleka okubandayo, xa iqondo lokubanda lomcu lingaphezulu kwama-70%, i-anisotropy yeplastiki iya kunyanzelwa emva kokufunxa. Xa iqondo lokubanda likwiqondo le-10% ~ 15%, iinkozo ziya kukhula ngokukhawuleza emva kokuthotywa, kwaye i-anisotropy yeplastiki ye-alloy nayo iya kuveliswa. I-anisotropy yeplastiki incinci xa isantya soxinzelelo sokugqibela singama-60% ~ 65% kunye nobukhulu beenkozo yi-7 ~ 8.5.
Iipropati ze-4J29 zokuwelda:
I-alloy inokudityaniswa ngobhedu, intsimbi, i-nickel kunye nezinye izinyithi ngokuxubha, i-fusion welding, i-welding resistance, njl. i-weld crack. Ngaphambi kokuba i-alloy ivalwe ngeglasi, kufuneka ihlanjululwe, ilandelwe ngukushisa okuphezulu okumanzi unyango lwe-hydrogen kunye nonyango lwangaphambili lwe-oxidation.
I-4J29 inkqubo yonyango lomphezulu: Unyango lwangaphezulu lunokuthi luqhunyiswe isanti, ukupolisha, ukucolwa.
Emva kokuba iinxalenye zitywinwe ngeglasi, ifilimu ye-oxide eyenziwa ngexesha lokutywinwa kufuneka isuswe ukuze i-welding lula. Amalungu angafudunyezwa malunga ne-70 ℃ kwisisombululo esinamanzi se-10% ye-hydrochloric acid + 10% ye-nitric acid, kwaye ifakwe kwi-2 ~ 5min.
I-alloy inokusebenza kakuhle kwe-electroplating, kwaye umphezulu unokuba yigolide, isilivere, i-nickel, i-chromium kunye nezinye izinyithi. Ukuze kube lula ukudibanisa i-welding okanye i-hot pressing bonding phakathi kwamalungu, ihlala ifakwe ngobhedu, i-nickel, igolide kunye ne-tin. Ukuze kuphuculwe i-conductivity ye-high frequency current kunye nokunciphisa ukuchasana koqhagamshelwano ukuqinisekisa iimpawu eziqhelekileyo zokukhutshwa kwe-cathode, igolide kunye nesilivere zihlala zifakwe. Ukuze kuphuculwe ukuxhathisa kwe-corrosion yesixhobo, i-nickel okanye igolide inokugqithwa.
4J29 Ukusika kunye nokusila ukusebenza:
Iimpawu zokusika ze-alloy zifana nezo ze-austenitic stainless steel. Ukucutshungulwa usebenzisa isantya esiphezulu sentsimbi okanye isixhobo se-carbide, ukucutshungulwa kwesantya esisezantsi. Isipholisi singasetyenziswa xa usikwa. I-alloy inomsebenzi omhle wokugaya.
