Insimbi engenasici i-alloy yensimbi equlethe ubuncinci be-chromium ye-10.5%. Ichromium idibana neoksijini esemoyeni kwaye yenza umaleko okhuselayo owenza intsimbi engatyiwayo imelane kakhulu nomhlwa kunye nomhlwa. Okwangoku, kukho iintlobo ezingaphezu kwe-150 zensimbi engenasici kwimarike.

Ngenxa yokugcinwa kwayo okuphantsi, ukuchasana ne-oxidation kunye ne-staining, insimbi engenasici ikhethwa kwizicelo ezininzi, ngakumbi ezo apho i-aesthetics ibalulekile.

Nokuba inazo ezi mpawu zinomtsalane, intsimbi engatyiwayo inako kwaye iyarusa emva kwayo yonke loo nto, 'ayinabala' hayi 'i-stainfree'. Ezinye iintlobo zentsimbi engatyiwa zithande ukubola kunezinye, kuxhomekeke kumxholo wechromium. Ukuphakama komxholo wechromium, incinci amathuba okuba isinyithi siya kuhlwa.

Kodwa, ekuhambeni kwexesha kwaye ukuba ayigcinwanga ngokuchanekileyo, umhlwa unako kwaye uya kukhula kwintsimbi engenasici.

Izinto ezichaphazela umhlwa kwintsimbi engatyiwayo

Izinto ezahlukeneyo zinokuchaphazela ukukwazi kwentsimbi engatyiwayo ukumelana nokubola. Ukubunjwa kwentsimbi yiyona nkxalabo enkulu xa kuziwa ekuchaseni ukubola. Izinto ezikumanqanaba ahlukeneyo ensimbi engenasici zinokuba nemiphumo emibi kwi-corrosion resistance.

Imekobume apho isinyithi sisetyenziswa yenye into enokwandisa amathuba okurusa kwentsimbi engatyiwayo. Imekobume eneklorini efana namadama okuqubha idlakadlaka kakhulu. Kwakhona, iindawo ezisingqongileyo ezinamanzi anetyuwa zinokukhawulezisa ukubola kwintsimbi engatyiwayo.

Ekugqibeleni, ulondolozo luya kuba nefuthe kwisakhono sesinyithi sokumelana nomhlwa. Ichromium ekwintsimbi engatyiwayo idibana neoksijini esemoyeni ukuvelisa umaleko okhuselayo wechromium oxide kumphezulu womhlaba. Nangona ubhityile kakhulu, olu maleko lulo olukhusela intsimbi ekudlekeni. Olu luhlu lunokutshatyalaliswa yimimandla enzima okanye umonakalo owenziwe ngomatshini onjengemikrwelo nangona kunjalo, ukuba uhlanjululwe ngokufanelekileyo kunye nendawo efanelekileyo, umgca wokukhusela uya kubumba kwakhona ukubuyisela iimpawu zokukhusela.

Iindidi zeNsimbi yeNsimbi eNgatyiwayo

Kukho iintlobo ezahlukeneyo zentsimbi ye-corrosion. Ngamnye kubo uveza imingeni eyahlukeneyo kwaye ufuna ukuphathwa ngendlela eyahlukileyo.

• Umhlwa jikelele – yeyona nto iqikelelwayo kwaye kulula ukuyiphatha. Kuphawulwa ngokulahleka okufanayo komphezulu wonke.
• I-Galvanic Corrosion - olu hlobo lwe-corrosion luchaphazela i-alloys ezininzi zetsimbi. Ibhekisela kwimeko apho enye isinyithi idibana nenye kwaye ibangele ukuba enye okanye zombini zisabele omnye komnye kwaye zidle.
• I-Pitting Corrosion – luhlobo lwendawo oluhlala kuyo olushiya imingxuma okanye imingxuma. Ixhaphakile kwiindawo ezinekloridi.
• I-Crevice Corrosion – kwakhona umhlwa wendawo owenzeka kwintanda phakathi kwemiphezulu emibini edityanisiweyo. Ingenzeka phakathi kweentsimbi ezimbini okanye intsimbi kunye nengeyontsimbi.

UyiNqanda Njani iNtsimbi eNgaxutywanga ekuMhlwa

Ukurusa intsimbi engatyiwayo kunokuba yinkxalabo kwaye kubonakale kungathandekiyo. Intsimbi yenzelwe ukuxhathisa umhlwa yiyo loo nto abasebenzisi abaninzi benoloyiko xa beqala ukuqaphela amabala kunye nokurusa kwintsimbi. Ngethamsanqa, kukho iindlela ezahlukeneyo kumanqanaba ahlukeneyo anokunceda ekuphuculeni umhlwa kunye nokuxhathisa umhlwa.

Yila

Ukulungiselela ngexesha lesigaba sokucwangcisa, xa usebenzisa insimbi engenasici, unokuhlawula ixesha elide. Qinisekisa ukuba isinyithi sisetyenziswa kwiindawo ezinokungena kwamanzi amancinci ukunciphisa umonakalo kumphezulu. Kwiimeko apho ukudibana namanzi kungenakuphepheka, imingxuma yokuhambisa amanzi kufuneka ifakwe. Uyilo kufuneka luvumele ukujikelezwa simahla komoya ukukhusela umonakalo kwi-alloy.

Ukwenziwa

Ngexesha lokwenziwa, inkathalo ekhethekileyo kufuneka ithathelwe kwindawo engqongileyo ukuphepha ukungcoliseka okunqamlezayo kunye nezinye iintsimbi. Yonke into esuka kwizixhobo, iiyunithi zokugcina, ii-rolling rolls kunye namatyathanga kufuneka zihlolwe ngokucophelela ukuba zingalahla ukungcola kwi-alloy. Oku kunokonyusa ukubunjwa okunokwenzeka komhlwa.

Isondlo

Emva kokuba i-alloy ifakiwe, ukugcinwa rhoqo ngundoqo kuthintelo lomhlwa, kwakhona kuthintela ukuqhubeka kwayo nayiphi na irusi enokuba sele yenzekile. Susa irusi eyenziwe ngoomatshini okanye ngemichiza kwaye ucoce ingxubevange ngamanzi ashushu kunye nesepha. Kufuneka kwakhona ugqume isinyithi ngengubo ekwazi ukumelana nomhlwa.
