Ubhedu lubhekisa kwiiialloyi zobhedungetoti njengeyona nto iphambili yokongeza.Kumaxesha anamhlanje, zonke ii-alloys zobhedu ngaphandle kobhedu zibandakanyiwe kudidi lobhedu, njenge-tin bronze, i-aluminium bronze, kunye ne-beryllium bronze.Kukwayinto yesiko ukwahlula ubhedu ngokwamacandelo amabini: ubhedu lwetin kunye ne-Wuxi bronze.Ikakhulu isetyenziselwa ukwenza iindawo ezikwaziyo ukumelana nomhlwa kunye nezingagugiyo, njengemikhono yeshaft, ii-thrust bearing pads, njl.Ezona zixhaphakileyo lubhedu lwe-aluminiyam, ubhedu olulothelwe kunye ne-beryllium bronze.I-aluminiyam yobhedu inokumelana nokugqwesa okungcono kunobhedu lwenkcenkce, kwaye isoloko isetyenziselwa ukwenza iindawo ezikwaziyo ukumelana nokurha kunye nezingagugiyo, njengeegiya, iigiya zeentshulube, amahlahla, njl. njl. njengabafowunelwa bombane, ii-electrode zoomatshini bokuwelda umbane, iiwotshi kunye neenxalenye zewotshi, njl.
Iindlela ezininzi zisetyenziselwe ukukhusela ubhedu, eyona nto ibalulekileyo yinkqubela phambili enkulu kuphando kunye nophuhliso usebenzisa i-corrosion inhibitors ezahlukeneyo.Okwangoku, iJapan inophando olubanzi ngakumbi nangakumbi kwitekhnoloji yokukhusela umphezulu wobhedu kunye nobhedu, ngakumbi kwicala lezinto zokwakha zokuhombisa, kwaye iphumelele amava amaninzi ayimpumelelo.Umsebenzi wasekhaya ugxile ikakhulu ekupholiseni umphezulu kunye nonyango lokuchasa ukuguga kweemveliso zobhedu, kwaye kukho inkqubela eyenziweyo.
Inkqubo yokuhamba kwe-copper kunye ne-alloy surface passivation yile: ukukhupha - ukuhlamba amanzi ashushu - ukuhlamba amanzi abandayo - ukucoca (i-hydrochloric acid egxininisiweyo okanye iqhekeza le-10%, ubushushu begumbi le-30s) - ukuhlamba koomatshini - ukuhlamba i-asidi enamandla - ukuhlamba amanzi - umphezulu ukulungiswa (30-90g /LCrO3, 15-30g/LH2S04, 15-30s)->ukuhlamba-ukuhlamba (112804 kunye neqhekeza elikhulu le-10%) ->ukuhlamba-ukuhlamba-ukuhlamba-ukuhlamba.Iifilimu ze-passivation ezingafanelekanga zobhedu kunye ne-alloys zethusi zingasuswa ngokucwiliswa kwisisombululo se-H2S04 kunye neqhekeza elitshisayo le-1,000, i-hydrochloric acid edibeneyo okanye i-300g / L isisombululo se-sodium hydroxide.
