Yiziphi izici ze-alloys zethusi nezethusi

I-Bronze ekuqaleni ibhekisela kuama-alloys ethusingethayela njengesithako esiyinhloko.Ezikhathini zanamuhla, wonke ama-alloys ethusi ngaphandle kwethusi afakiwe esigabeni sethusi, njengethusi le-tin, i-aluminium bronze, ne-beryllium bronze.Kuyisiko futhi ukuhlukanisa ithusi ngezigaba ezimbili: i-tin bronze ne-Wuxi bronze.Isetshenziswa kakhulu ukwenza izingxenye ezimelana nokugqwala nezingagugi, njengemikhono ye-shaft, amaphedi athwala ama-thrust, njll. Ngenxa yezinsiza ezilinganiselwe zikathayela, ezinye izakhi ze-alloying zisetshenziswe kabanzi embonini muva nje ukuze kuthathelwe indawo ithayela.Okuvame kakhulu ithusi le-aluminium, i-lead bronze kanye ne-beryllium bronze.Ithusi le-aluminum likwazi ukumelana nokugqwala okungcono kunethusi eliwuthayela, futhi livame ukusetshenziselwa ukwenza izingxenye ezimelana nokugqwala nezingagugi, njengamagiya, amagiya wezikelemu, amabhushi, njll. Ithusi le-beryllium lisetshenziselwa kakhulu iziphethu ezibalulekile nezingxenye ezinwebekayo, futhi njengama-contact kagesi, ama-electrode emishini yokushisela kagesi, amawashi nezingxenye zewashi, njll.

Kusetshenziswe izindlela eziningi ukuvikela ithusi, okubaluleke kakhulu okuyinqubekelaphambili enkulu ocwaningweni nasekuthuthukisweni kusetshenziswa ama-corrosion inhibitors ahlukahlukene.Njengamanje, iJapane inocwaningo olubanzi futhi olubanzi mayelana nobuchwepheshe bokuvikela ubuso be-alloy yethusi ne-alloy, ikakhulukazi esicini sezinto zokwakha zokuhlobisa, futhi izuze isipiliyoni esiyimpumelelo.Umsebenzi wasekhaya ugxile kakhulu ekupholishweni komhlaba kanye nokwelashwa kokushintsha umbala kwemikhiqizo yethusi, futhi sekukhona nenqubekelaphambili eseyenziwe.

Inqubo yokugeleza kwe-copper ne-alloy surface passivation yile: ukwehlisa - ukugeza amanzi ashisayo - ukugeza amanzi abandayo - ukukhethwa (i-hydrochloric acid egxilile noma ingxenyena enkulu ye-10%, izinga lokushisa legumbi lama-30s) - ukugeza ngomshini - ukuwasha nge-asidi eqinile - ukugeza amanzi - ngaphezulu conditioning (30-90g /LCrO3, 15-30g/LH2S04, 15-30s)->washing-pickling (112804 nge mass ingxenye 10%)->washing-passivation-washing-drying.Amafilimu e-passivation angafanelekile wethusi nama-alloys ethusi angasuswa ngokucwiliswa kusisombululo se-H2S04 ngengxenye eshisayo ye-1,000, i-hydrochloric acid egxilile noma i-300g/L yesisombululo se-sodium hydroxide.
