Ngenxa yokuba umbhobho wentsimbi etyebileyo oyi-316L enodonga olungqingqwa awuxhathisi, awunyangeki, kwaye uyaxhathisa kubushushu obuphezulu, uhlala usetyenziswa kumayeza, kushishino lweekhemikhali, ukutya, ishishini elikhanyayo, oomatshini bekhemikhali, imibhobho yeshishini, kunye namalungu oomatshini. Ngokuqinisekileyo, imibhobho yentsimbi enodonga olungqingqwa nayo ifanelekile ukuveliswa kunye nokuveliswa kwemibhobho yokukhupha kunye nemibhobho eyahlukeneyo esisiseko. Nangona kunjalo, imibhobho yentsimbi enodonga olungqingqwa idlakadlaka emva kwexesha elithile isetyenziswa. Ke, kufuneka ndenze ntoni ukuba imibhobho yentsimbi etyebileyo enodonga olungqindilili ye-316L idlekile?

Siyazi ukuba xa i-316L imibhobho yensimbi engenasici etyebileyo idliwe yi-thermocouples, i-anodic oxidation iyatshatyalaliswa kwaye i-electrode engalunganga igcinwa. Ukuba sizama ukugcina umbhobho wentsimbi etyebileyo enodonga olungqindilili njenge-electrode engakhiyo ukusuka ekuqaleni ukuya ekupheleni, umbhobho wentsimbi awuyi kudleka lula. Le ndlela yokunqanda ukubola ibizwa ngokuba yi-pipeline cathodic protection. Le ikwayindlela yokukhapha. Ayisebenzisi kuphela izinto zetsimbi ezihambayo njengeefilim ezikhuselayo kodwa iphinda itshabalalise izinto zetsimbi ezihambayo kwaye igcine iinxalenye zentsimbi. Uphando olongezelelekileyo lwezenzululwazi lunokwenziwa ngaphandle kokutshabalalisa i-anodic oxidation. Ngoko ke, indlela yokukhusela i-cathodic inokwahlulwa ibe yindlela yokukhusela ifilimu kunye nendlela yokukhusela izixhobo zombane.

Nge-alloy esebenzayo njengefilimu ekhuselayo, yifake kumbhobho we-316l okhuselayo wensimbi engenasici, okanye udibanise isinyithi esikhuselayo ngocingo, ukwenzela ukuba ifilimu yokukhusela kunye nentsimbi ekhuselayo ibe ngamacala amabini e-galvanic cell reaction. Ekubeni ifilimu ekhuselayo iyintsimbi esebenzayo, inempembelelo ye-anodic oxidation kwibhetri, i-oxidized kwaye yonakaliswe ngumoya ongcolileyo, kwaye i-alloy ekhuselayo yi-cathode. Ibhetri encinci yokuqala iyayeka okanye iyancipha kumsebenzi we-cathode, kwaye emva koko ikhusela iindawo zentsimbi. Xa ifilimu ekhuselayo izakugqwala, inokutshintshwa enye ifilimu ekhuselayo.

Ngoko ke, le ndlela yokulwa ne-corrosion yindlela yokukhusela imoto elahlekileyo, eyaziwa ngokuba yindlela yokukhusela i-cathodic. Ngokomzekelo, kukho iibhloko ze-zinc kwiibhoyila zegesi, kwaye i-zinc ihlala igxininisekile kwiipropeller zeenqanawa. I-Zinc isebenza ngakumbi kune-iron, ngoko ke i-zinc idla ngokucotha kwaye ikhusela iziko kunye neepropellers. Ngexesha lenkqubo ye-electrolysis, i-electrode exhunywe kwisibonda esibi sonikezelo lwamandla akulula ukuba lonakaliswe. Kule electrode, i-electron ayikho imfuneko, ngoko udonga olubi lwe-316L eludongeni olungqingqwa lombhobho wensimbi engenasici ngokwalo alukwazi ukulahlekelwa ii-electron kwaye lube ionni ezilungileyo.

Ngamanye amazwi, i-electrode engalunganga ayilula ukuba yonakaliswe. Ngokwalo mgaqo usisiseko, sinokusebenzisa lwangoku lwangaphandle ukudibanisa intsimbi eshinyeneyo-engqingqwa umbhobho yentsimbi kunye noqhagamshelo olubi lonikezelo lwamandla utshintshe njengonxibelelwano olubi, seta unikezelo lombane oluncedisayo kunye nepali elungileyo yonikezelo lombane lokutshintsha njengoko uqhagamshelo lwe-anodic oxidation, kwaye emva koko ugcine izixhobo ezingalunganga zoomatshini. I-Anodizing inokuba yimibhobho yamanzi amdaka, iingoma ezindala zikaloliwe, njl., ezidla ngokucothayo phantsi kweemeko eziphantsi. Le ndlela ifana nendlela yokukhusela ifilimu.
