Ndeapi maitiro emhangura nemhangura alloys

Bronze pakutanga inorevaalloys emhanguranetin sechinhu chikuru chekuwedzera.Munguva dzazvino, ese alloys emhangura kunze kwendarira anosanganisirwa 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 inowanzoshandiswa kugadzira simbi isingaore uye isingapfeki, senge magiya, giya rehonye, ​​bushings, etc. Beryllium bronze inonyanya kushandiswa kune zvakakosha zvitubu uye elastic parts, pamwe nemagetsi contactors, electrodes yemagetsi welding machines, clock parts, etc.

Nzira dzakawanda dzakashandiswa kuchengetedza mhangura, iyo inonyanya kukosha iyo ndiyo kufambira mberi kukuru mukutsvakurudza uye kubudirira uchishandisa zvakasiyana-siyana corrosion inhibitors.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.

The process flow of copper and copper alloy surface passivation is: degreasing – kugeza mvura inopisa – kugeza mvura inotonhora – pickling (concentrated hydrochloric acid or mass fraction of 10%, room temperature 30s) – kugeza nemuchina – strong acid washing – water washing – surface conditioning (30-90g /LCrO3, 15pi-10-20)> (112804 ine chikamu chikuru che10%) -> kugeza-passivation-kugeza-kuomesa.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.
