I-Sorrosion yinto ephantsi apho i-tictois isebenza khona ikhemikhali okanye i-elektrochemical impendulo kunye nezinto ezikufutshane, ezikhokelela ekuhlazeni. Nokuba kubomi bethu bemihla ngemihla, okanye kwimveliso yemidlalo, okanye kwimveliso yemizi-mveliso, isinyithi "sinokubonwa kuyo yonke indawo, ukusuka kwi-scrosion encinci, iimoto ezinkulu, iinqwelomoya, iibhulorho kunye nezinye iibhloksi. Ukuvela akuyi kubangela ilahleko yoqoqosho kuphela, kwaye kukhokelele kwiingozi zokhuseleko, ukubaluleka kokuchasana nokungavisisani akufuneki kuthathelwe ingqalelo.
Kumda womda wesithamo, umaleko wokuqala wokuqalisa uya kwenziwa. Ngenxa yobukho beoksijini emoyeni, unamathele ngokuphinda usandul 'ukuphendula zihlala zikhona ngohlobo lwe-oxide kwaye ke ngoko ifilimu eyisilivere (POF). Lo mbandela uhlala uthambile kwaye kuqala uthintele ukuqaqanjelwa ngakumbi.
Phezu komaleko wokuphendula, izinto eziqokelela kwi-adredleemers. Ngokwesiqhelo eyokuqala ngamanzi, nto leyo, ngenxa yesimo se-amphoteraide yentsimbi, iphinde yenze ifilimu yesiseko se-oxide kwi-acid-isiseko, apho ezinye izinto ezisebenzayo zinokungena. Lo mlinganiso ngumchiza wemihlathi, oboshwe ngamandla kwaye kunzima ukuphinda uchithe. Umaleko we-shemissiption ulandelwa ngokusondeleyo ngumaleko we-adsorption, onesifo seengcongconi esibambekayo kwaye itshintshwa ngokulula.
Ifilimu eyintloko ye-oxide yeyona nguqumbululo obaluleke kakhulu wokunganyangeki, umthamo wefilimu, eyomeleleyo kakhulu, kokukhona ukumelana nokunganyangeki. Ngamanye amagama, ukhuseleko lwe-corosion kufuneka luqaliswe ngexesha lokuqulunqwa kunye nokuzinza kwefilimu ye-ox ox). Kuxhomekeka kwimiba yentsimbi, i-onsortives (umzekelo, i-suntfacapes, iiarhente zeRenox) ziyafuneka. I-Corrosion ihlala iqala ngokubola kwefilimu ye-oxide ye-oxide, enokubakho kwintsimbi engenamthubi, kodwa kwintsimbi engenasitali ifilimu esizinzileyo ngenxa yobukho bamacandelo alo (ngakumbi i-chromium).
I-Colosion eqhelekileyo ebomini ineentlobo ezahlukeneyo zentetho, makhe sijonge ezi ntlobo zisixhenxe zibalulekileyo zesulelo.
I-1. Ukhukuliseko lwe-erosion:Isinyithi sibekwe phantsi kokukhuphela phantse kumphezulu. Yeyona ndlela ixhaphakileyo ye-corosion kwaye ihlala ibangelwa ngamanzi okanye umoya omdaka.
I-2. I-Crevice School:I-crevices phakathi kwezinyithi okanye amalungu olwakhiwo inokukhokelela ekucocekeni okukhulu kuba i-electroyte igcinwa ngentshukumo ye-capillary kwaye isenokuvelisa umahluko omkhulu. Oku kunokuthintelwa ngokufanelekileyo ngamanyathelo okulondolozwa.
I-3. Qhakamshelana noTorrosion:I-Electrochemical Sorposion ezibangelwa ziintsimbi ezimbini ezingafaniyo nokunxibelelana nangaxesha elinye kwi-electrolyte, kunye nenye yeentsimbi eziguqulweyo ngexabiso elikhawulezayo. Ingathintelwa ngokukhetha izixhobo ezifanelekileyo okanye ukuphazamisa ukuqhubela phambili phakathi kwezixhobo.
I-4. Ukuphatha:Ukuthambisa iziphumo ekwinkalelani, ukulungiselela okanye ukuphefumla. Ihlala ibangelwa kukukhanyisa umonakalo kwingqimba yokukhusela, enjenge-pores kwi-course okanye i-chloride kukhuthaza umaleko wevenkile.
5. I-Trasion yeTriner:Inxalenye yentsimbi yeCR kunye neCrni Austetitic kwimida yengqolowa ikhulisiwe, oku kusondela kuya kwenza ukuba iqhekeza phakathi kweenkozo zenziwe buthathaka. I-Contrasion enkulu yosulelo inokwenza ukuba isinyithi siphulukane namandla kunye nexesha, ukuqhekeza phantsi komthwalo oqhelekileyo, unyango olufanelekileyo lokuthabatha kukuthintela ukuvela kwe-intergrawule.
I-6. I-Dew-Poisotion Sormosion:I-Dew-Potion Stosion ibhekisa kwi-steam egxunyekwe ngenxa yokupholisa kunye nokufumana i-woulting kwinto ebangelwe yi-corrosion, intsimbi engenalo intsimbi, kwaye kufuneka ikhuselwe ngomaleko ofanelekileyo.
I-7. Ukunyanzelwa koxinzeleloKwimidiya yobutyebi, ngelixa uphantsi koxinzelelo ngoomatshini kwezinto eziya kwenza ukuba ii-rocks, ngakumbi kwi-chlorine kunye nezisombululo ze-alkali ezomeleleyo, ziya kukhokelela kwintsimbi ye-curnico austicocic yoxinzelelo.
