Imitha yokugqwala ye-Metallographic electrolytic luhlobo lwesixhobo esisetyenziselwa unyango lomphezulu kunye nokujonga iisampuli zesinyithi, esisetyenziswa kakhulu kwisayensi yezinto, i-metallurgy kunye nokucubungula isinyithi. Eli phepha liza kwazisa ukusetyenziswa kwemitha yokugqwala ye-metallographic electrolytic.
Amanyathelo emitha yokugqwala kwe-metallographic electrolytic ngala alandelayo:
Inyathelo 1: lungiselela isampuli.
Ukulungiswa kwesampulu yesinyithi ukuze ijongwe ngobukhulu obufanelekileyo kudla ngokufuna ukusikwa, ukupolisha kunye nokucoca ukuqinisekisa ukugqitywa komphezulu kunye nokucoceka.
Inyathelo lesi-2: Khetha i-electrolyte efanelekileyo. Khetha i-electrolyte efanelekileyo ngokwezinto ezifunekayo kunye neemfuno zokujonga zesampuli. Ii-electrolyte ezisetyenziswa rhoqo ziquka i-electrolyte ene-acid (efana ne-sulfuric acid, i-hydrochloric acid, njl.njl.) kunye ne-alkaline electrolyte (efana nesisombululo se-sodium hydroxide, njl.njl.).
Inyathelo lesi-3: Ngokweempawu zezinto zesinyithi kunye neemfuno zokujonga, uxinano lwangoku, i-voltage kunye nexesha lokugqwala zilungiswa ngokufanelekileyo.
Ukukhethwa kwezi parameters kufuneka kuphuculwe ngokusekelwe kumava kunye neziphumo zovavanyo zokwenyani.
Inyathelo lesi-4: Qalisa inkqubo yokubola. Faka isampuli kwiseli ye-electrolytic, uqinisekise ukuba isampuli inxibelelana ngokupheleleyo ne-electrolyte, kwaye uqhagamshele umbane ukuze uqalise umbane.
Inyathelo lesi-5: Jonga inkqubo yokugqwala. Jonga utshintsho kumphezulu wesampulu, ngesiqhelo phantsi kwemakroskopu. Ngokwemfuneko, ukugqwala okuninzi kunye nokujonga kungenziwa de kufunyanwe isakhiwo esincinci esaneleyo.
Inyathelo lesi-6: Yeka ukugqwala uze ucoce isampuli. Xa kubonwa isakhiwo esincinci esaneleyo, umbane uyamiswa, isampuli isuswe kwi-electrolyzer ize icocwe kakuhle ukuze kususwe i-electrolyte eseleyo kunye neemveliso zokugqwala.
Ngamafutshane, i-metallographic electrolytic corrosion meter sisixhobo esibalulekileyo sohlalutyo lwezinto, esinokubona kwaye sihlalutye isakhiwo seesampuli zesinyithi ngokukrola umphezulu. Umgaqo ochanekileyo kunye nendlela efanelekileyo yokusebenzisa inokuqinisekisa ukuchaneka nokuthembeka kweziphumo zokubola, kwaye inike inkxaso enamandla kuphando kwicandelo lesayensi yezinto kunye nokucubungula isinyithi.
