Kushanda kwemetallographic electrolytic corrosion mita

Metallographic electrolytic corrosion meter imhando yechiridzwa chinoshandiswa pakurapa kwepamusoro uye kutarisa kwesimbi samples, iyo inoshandiswa zvakanyanya muzvinhu zvesainzi, simbi uye simbi kugadzirisa.Iri bepa richasuma kushandiswa kwemetallographic electrolytic corrosion mita.

Matanho eiyo metallographic electrolytic corrosion mita ndeaya anotevera:

Danho 1: gadzirira muenzaniso.

Kugadzirira kwesimbi sampuli kuti ionekwe kuhukuru hwakakodzera kazhinji kunoda kucheka, kupenya uye kuchenesa kuti ive nechokwadi chekupedza uye kuchena.

Danho 2: Sarudza yakakodzera electrolyte.Sarudza iyo yakakodzera electrolyte zvinoenderana nezvinhu uye zvekutarisa zvinodiwa zvemuenzaniso.Inowanzo shandiswa electrolyte inosanganisira acidic electrolyte (yakadai se sulfuric acid, hydrochloric acid, nezvimwewo) uye alkaline electrolyte (yakadai se sodium hydroxide solution, nezvimwewo).

Nhanho 3: Zvinoenderana nehunhu hwesimbi zvinhu uye zvinodikanwa zvekutarisa, density iripo, voltage uye nguva yekuora zvinogadziriswa zvakakodzera.
Sarudzo yeaya ma parameter inoda kuvandudzwa zvichienderana neruzivo uye mhedzisiro chaiyo yebvunzo.

Danho 4:Tanga iyo corrosion process.Isai sample musero re electrolytic, onai kuti sampu yacho yasangana zvizere neelectrolyte, uye batanidza magetsi kutanga ikozvino.

Nhanho 5: Tarisa maitiro ekuora.Tarisa shanduko pamusoro peiyo sampuli, kazhinji pasi pemaikorosikopu.Zvinoenderana nezvinodiwa, kukora kwakati uye kutarisa kunogona kuitwa kusvika inogutsa microstructure yawanikwa.

Nhanho yechitanhatu: Misa ngura uye sampuli yakachena.Kana microstructure inogutsa ichionekwa, ikozvino inomiswa, sampu inobviswa kubva ku electrolyzer uye yakanyatsocheneswa kubvisa yakasara electrolyte uye ngura zvigadzirwa.

Muchidimbu, metallographic electrolytic corrosion mita chinhu chakakosha chekuongorora zvinhu, chinogona kuona uye kuongorora iyo microstructure yemasampure esimbi nekuisa pamusoro.Nheyo chaiyo uye nzira yekushandisa chaiyo inogona kuve nechokwadi uye kuvimbika kwemhedzisiro yecorrosion, uye kupa rutsigiro rwakasimba rwekutsvagisa mumunda wezvekushandisa sainzi uye kugadzira simbi.
