Iningi lokugqwala ngezinto zensimbi livela ezindaweni ezinomkhathi, eziqukethe izici zokuvuselelwa izimpikiswano kanye nezinto ezinjenge-oxygen, umswakama, ukuhlukahluka okuvimbela izilinganiso, nokungcola. I-Solk Spray Spray Corrusion iyindlela ejwayelekile futhi ebhubhisayo yokugqwala komkhathi.
Ukugcwala kukasawoti ngokukhethekile kubandakanya ukuvumela izixazululo zikasawoti eziphethe ngaphakathi kwezinto zensimbi, okuholela ekuphendukeni kwe-electrochemical. Lokhu kuphumela ekwakhekeni kwamaseli we-microgalvalvalvalvalvalvalvalvalval, "ngesixazululo esiphansi sensimbi-electrol-electrol-electrollyte -" ukungcoliseka okungukungcola okuphezulu kakhulu ". Ukudluliswa kwe-elektroni kwenzeka, futhi i-metal esebenza njengoba i-anode incibilika, yakha amakhompiyutha amasha, ie, imikhiqizo yokugqwala. I-Chloride ion idlala indima ebaluleke kakhulu kwinqubo yokugqwala yesifutho sikasawoti. Banamakhono wokungena ngokuqinile, bangena kalula ungqimba lwensimbi ye-oxide futhi uphazamisa isimo se-Metal Prastivation. Ngaphezu kwalokho, i-chloride ion inamandla aphansi we-hydration, okwenza ukuthi basebenzise kahle i-adsorb ibe yinsimbi, isusa umoya-mpilo ngaphakathi kwensimbi yokuvikela i-oxide oxide, ngaleyo ndlela ibangele ukulimala kwensimbi.
Ukuhlolwa koSawoti isifutho kuhlukaniswa ngezinhlobo ezimbili eziphambili: Ukuhlolwa kokuvezwa kwemvelo kwezemvelo kanye nokuhlolwa kosawoti okusheshayo okusheshayo okusheshisiwe. Lesi sakamuva sisebenzisa ama-appatus wokuhlola, okwaziwa ngokuthi yi-Salt Spray Test Chamber, enovolumu elawulwayo futhi akhiqize imvelo kasawoti ngokungemthetho. Kuleli qembu, imikhiqizo ihlolwe ngokumelana kwayo kusawoti fafaza ukugqwala. Uma kuqhathaniswa nezimo zemvelo, okuhlushwa usawoti endaweni yokufafaza usawoti kungaba kaningana noma amashumi ezikhathi eziphakeme, ukusheshisa kakhulu isilinganiso sokukhulisa. Ukwenza izivivinyo zokufafaza usawoti kwimikhiqizo zivumela isikhathi esifushane sokuhlola, imiphumela ifana kakhulu nemiphumela yokuvezwa kwemvelo. Isibonelo, ngenkathi kungathatha unyaka owodwa ukuhlola ukonakala kwesampula yomkhiqizo endaweni yemvelo yangaphandle, eqhuba isivivinyo esifanayo emvelweni yendawo yokufafaza ngosawoti eyenziwe ngamahora angama-24 kuphela.
Ukulingana phakathi kokuhlolwa kosawoti wesawoti kanye nesikhathi sokuvezwa kwemvelo kwemvelo kungafingqiwe kanjena:
Amahora angama-24 wokuhlolwa kosawoti okungathathi hlangothi ≈ unyaka owodwa wokuvezwa kwemvelo.
Amahora angama-24 wokuhlola usawoti we-acetic acid usawoti ≈ Iminyaka emithathu yokuvezwa kwemvelo.
Amahora angama-24 we-acetic aceli acebile ashelelezi ashelelezi - iminyaka engu-8 yokuvezwa kwemvelo.
