Ukuthuthukiswa kokusebenza kwe-Silver alloy

Isiliva lithambile ngokwedlulele futhi kulula ukulicubungula.Ukuze kuthuthukiswe amandla nokuqina kwayo futhi kwandise ukumelana kwayo nokugqoka, abantu baye bafaka isikhathi eside ithusi esiliva ukuze benze ama-alloys esiliva-ethusi, asetshenziselwa ubucwebe, i-tableware nezinhlamvu zesiliva.Ukuze kuthuthukiswe ukusebenza kwama-alloys esiliva-ethusi, i-nickel, i-beryllium, i-vanadium, i-lithium nezinye izingxenye zesithathu kuvame ukungezwa ukwenza ama-ternary alloys.Ngaphezu kwalokho, kunezinye izakhi eziningi ezingezwe esiliva nazo zingadlala indima yokuqinisa.Umthelela wezakhi ze-alloying ku-Brinell ubulukhuni besiliva uboniswa ku-Figure 1. I-Cadmium nayo iyisici esivame ukusetshenziswa esiqinisayo.

Nakuba isiliva lingangeni emkhathini wezinto eziphilayo, ligqwala kalula futhi libe nesibabule ngenxa yesimo sezulu esinesibabule.Ukuthuthukisa ukumelana kwesiliva ku-sulfid nakho kungokusebenzisa ingxubevange, njengokwengeza igolide ne-palladium ukuze kwehliswe izinga lokwakheka kwefilimu ye-sulfide yesiliva.Ngaphezu kwalokho, izakhi eziningi zensimbi eziyisisekelo ezifana ne-manganese, i-antimony, i-tin, i-germanium, i-arsenic, i-gallium, i-indium, i-aluminium, i-zinc, i-nickel, ne-vanadium nayo ingafakwa esiliva ukuze kuthuthukiswe ukumelana kwayo nesibabule.Kunezinhlobo eziningi zezinto zokuxhumana zikagesi ezisekelwe esiliva, esimweni esihlanganisiwe, futhi zingenziwa zibe ama-alloys mbumbulu nge-powder metallurgy.Inhloso yabo ukuqinisa, ukugqoka nokuthuthukisa ukusebenza kokuxhumana kagesi.Ngezinjongo ezahlukene, ngokuvamile engeza izingxenye eziningi.Ohlotsheni lwe-alloy-low-power low-sliding materials, i-manganese, i-iridium, i-bismuth, i-aluminium, i-lead noma i-thallium ivame ukungezwa ukwandisa ukumelana nokugqokwa.I-alloy-based alloy brazing filler metal iwuhlobo lwensimbi yokugcwalisa enezinhlobo eziningi, esetshenziswa kakhulu, kanye nenani elikhulu lezinsimbi eziyigugu zokugcwalisa izinsimbi.Izidingo eziyinhloko zama-alloys e-brazing ukushisa kwe-welding, indawo yokuncibilika, ukumanzisa namandla okushisela.Ama-alloys esiliva njengezinsimbi zokugcwalisa i-brazing ngokuvamile afakwa ngethusi, i-zinc, i-cadmium, i-manganese, i-tin, i-indium nezinye izakhi ze-alloying ukuthuthukisa ukusebenza kokushisela.
