Ndeapi maitiro emhangura nemhangura alloys

Bronze pakutanga inorevaalloys emhanguranetin sechinhu chikuru chekuwedzera.Munguva dzazvino, zvese zviwanikwa zvemhangura kunze kwendarira zvinosanganisirwa muchikamu chebhuronzi, senge tin bronze, aluminium bronze, uye beryllium bronze.Itsika zvakare kupatsanura bronze muzvikamu zviviri: tin bronze uye Wuxi bronze.Inonyanya kushandiswa kugadzira masimbi asingaite ngura uye asingapfeki, semaoko eshaft, ma thrust bearing pads, nezvimwewo. Nekuda kwekushomeka kwemarata, mamwe maalloying anoshandiswa zvakanyanya muindasitiri munguva pfupi yapfuura kutsiva marata.Anonyanya kuzivikanwa ndeye aluminium bronze, lead bronze uye beryllium bronze.Aluminium bronze ine corrosion resistance iri nani pane tin bronze, uye inowanzo shandiswa kugadzira zvinhu zvisingaite corrosion uye zvisingapfeki, zvakaita semagiya, giya rehonye, ​​bushings, nezvimwewo. Beryllium bronze inonyanya kushandiswa kuzvitubu zvakakosha uye zvikamu elastic, zvakare. semagetsi ekubatanidza, maelectrodes emagetsi welding michina, wachi uye zvikamu wachi, nezvimwe.

Nzira dzakawanda dzakashandiswa kuchengetedza mhangura, iyo inonyanya kukosha ndeyekufambira mberi kukuru mukutsvakurudza uye kubudirira uchishandisa corrosion inhibitors dzakasiyana-siyana.Parizvino, Japan ine yakawedzera uye yakawedzera tsvagiridzo yemhangura nemhangura alloy pamusoro pekudzivirira tekinoroji, kunyanya muchikamu chezvivakwa zvekushongedza zvinhu, uye yakawana ruzivo rwakawanda rwakabudirira.Basa remumba rinonyanya kutarisisa kukwenenzverwa kwepasi uye anti-discoloration kurapwa kwezvigadzirwa zvemhangura, uye kumwe kufambira mberi kwakaitwawo.

Kuyerera kwemhangura nemhangura alloy pamusoro passivation ndeiyi: degreasing - kugeza mvura inopisa - kugeza mvura inotonhora - pickling (concentrated hydrochloric acid or mass fraction of 10%, room temperature 30s) - kugeza muchina - kugeza asidhi yakasimba - kugeza mvura - pamusoro. conditioning (30-90g /LCrO3, 15-30g/LH2S04, 15-30s)->washing-pickling (112804 nechikamu chikuru che10%) ->washing-passivation-washing-drying.Mafirimu asina kukodzera ekufambisa emhangura nemhangura anogona kubviswa nekunyura mumhinduro yeH2S04 ine chikamu chinopisa chinopisa che1,000, concentrated hydrochloric acid kana 300g/L sodium hydroxide solution.
