Ubhedu lubhekisa ekuqaleniiialloyi 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.Kukwalisiko 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.Ubhedu lwe-aluminiyam lunokumelana nokugqwesa okungcono kunobhedu lwe-tin, kwaye luhlala lusetyenziselwa ukwenza iindawo ezinganyangekiyo kunye nezingagugiyo, njengeegiya, iigiya zeentshulube, i-bushings, njl.njl. Ubhedu lwe-beryllium lusetyenziswa ikakhulu kwimithombo ebalulekileyo kunye neenxalenye ezilastiki, kunye nee-contactors zombane, i-electrodes yombane welding machines, iiwotshi kunye neewotshi.
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 kobhedu kunye nobhedu lwe-alloy surface passivation yi: degreasing - ukuhlamba amanzi ashushu - ukuhlamba amanzi abandayo - pickling (i-hydrochloric acid egxininisiweyo okanye iqhezu elikhulu le-10%, ubushushu begumbi le-30s) - ukuhlamba koomatshini - ukuhlamba okuqinileyo kwe-asidi - ukuhlamba amanzi - ukulungiswa komphezulu (30-90g /LCrO3g/15pick-120) (112804 kunye neqhekeza elikhulu le-10%) -> ukuhlamba-passivation-washing-drying.Iifilimu ze-passivation ezingafanelekanga zobhedu kunye ne-alloys zethusi zingasuswa ngokucwina kwisisombululo se-H2S04 kunye neqhekeza elitshisayo le-1,000, i-hydrochloric acid edibeneyo okanye i-300g / L isisombululo se-sodium hydroxide.
