Ukusebenza kwemitha yokugqwala kwe-metallographic electrolytic

Imitha yokugqwala ye-Metallographic electrolytic uhlobo lwethuluzi elisetshenziselwa ukwelashwa kwendawo kanye nokubuka amasampula ensimbi, elisetshenziswa kabanzi kwisayensi yezinto zokwakha, i-metallurgy kanye nokucubungula insimbi. Leli phepha lizokwethula ukusetshenziswa kwemitha yokugqwala ye-metallographic electrolytic.

Izinyathelo zemitha yokugqwala kwe-metallographic electrolytic yilezi ezilandelayo:

Isinyathelo 1: lungiselela isampula.

Ukulungiswa kwesampula yensimbi ukuze ibhekwe ngobukhulu obufanele ngokuvamile kudinga ukusika, ukupholisha kanye nokuhlanza ukuqinisekisa ukuqedwa nokuhlanzeka kwendawo.

Isinyathelo 2: Khetha i-electrolyte efanele. Khetha i-electrolyte efanele ngokwezidingo zezinto ezibonakalayo kanye nokubuka kwesampula. Ama-electrolyte asetshenziswa kakhulu afaka i-electrolyte ene-acid (njenge-sulfuric acid, i-hydrochloric acid, njll.) kanye ne-alkaline electrolyte (njengesisombululo se-sodium hydroxide, njll.).

Isinyathelo 3: Ngokwezici zezinto zensimbi kanye nezidingo zokubuka, ubuningi bamanje, i-voltage kanye nesikhathi sokugqwala kulungiselelwa ngendlela efanele.
Ukukhethwa kwalezi zinhlaka kudinga ukwenziwa ngcono ngokusekelwe kokuhlangenwe nakho kanye nemiphumela yangempela yokuhlolwa.

Isinyathelo 4: Qala inqubo yokugqwala. Faka isampula kuseli ye-electrolytic, qiniseka ukuthi isampula ixhumene ngokuphelele ne-electrolyte, bese uxhuma ugesi ukuze uqale ugesi.

Isinyathelo 5: Qapha inqubo yokugqwala. Bheka izinguquko ebusweni besampula, ngokuvamile ngaphansi kwe-microscope. Ngokwesidingo, ukugqwala okuningana kanye nokubuka kungenziwa kuze kutholakale isakhiwo esincane esanelisayo.

Isinyathelo 6: Misa ukugqwala bese uhlanza isampula. Uma kubonwa isakhiwo esincane esanelisayo, ugesi uyamiswa, isampula iyasuswa ku-electrolyzer bese ihlanzwa kahle ukuze kususwe i-electrolyte esele kanye nemikhiqizo yokugqwala.

Ngamafuphi, i-metallographic electrolytic corrosion meter iyithuluzi elibalulekile lokuhlaziya izinto, elingabona futhi lihlaziye isakhiwo esincane samasampula ensimbi ngokuqopha ubuso. Isimiso esinembile kanye nendlela efanele yokusebenzisa kungaqinisekisa ukunemba nokuthembeka kwemiphumela yokugqwala, futhi kunikeze ukwesekwa okuqinile kocwaningo emkhakheni wesayensi yezinto zokwakha kanye nokucubungula insimbi.
