Yenziwe ngentsimbi eshayinayoIyaziwa ngokumelana nokugqwala, kodwa ayinayo ngokupheleleyo i-rust. Intsimbi engagqwaliyo inokugqwala phantsi kweemeko ezithile, kwaye ukuqonda isizathu sokuba oku kwenzeke kunokunceda ukuthintela nokulawula ukugqwala.
Intsimbi engatyiwayo ine-chromium, eyenza umaleko we-oxide obhityileyo, ongasebenziyo kumphezulu wayo xa ufakwe kwi-oxygen. Le maleko ye-oxide, eyaziwa ngokuba yi-"passive maleko," inika ukumelana nokugqwala okubangela ukubayenziwe ngentsimbi eshayinayoidume kakhulu.
Izinto Ezichaphazela Umhlwa Kwintsimbi Engagqwaliyo：
Ukuvezwa kwiChlorides
Umonakalo woomatshini
Ukunqongophala kweoksijini
Ungcoliseko
Amaqondo obushushu aphezulu
Intsimbi Engagqwaliyo Ekumgangatho Ophantsi
Iindawo ezinobungozi zeekhemikhali
Iintlobo zeStainless Steel Corrosion:
Kukho iintlobo ezahlukeneyo zokubola kwentsimbi engagqwaliyo. Ngayinye kuzo inemingeni eyahlukeneyo kwaye ifuna ukuphathwa ngendlela eyahlukileyo.
Ukugqwala ngokubanzi– yeyona iqikelelwayo kwaye kulula ukuyiphatha. Iphawulwa kukulahleka okufanayo komphezulu wonke.
Ukubola kweGalvanic– olu hlobo lokugqwala luchaphazela uninzi lwee-alloys zesinyithi. Lubhekisa kwimeko apho isinyithi esinye sidibana nesinye kwaye sibangele ukuba esinye okanye zombini zisabelane kwaye zigqwale.
Ukugqwala kwe-pitting– luhlobo lokonakala oluhlala kwindawo ethile olushiya imingxunya okanye imingxuma. Luxhaphake kakhulu kwiindawo ezinee-chloride.
Ukugqwala komqolomba– kukwakho nokugqwala okwenzeka kwindawo ethile kwimfanta ephakathi kwemiphezulu emibini edibanisayo. Kunokwenzeka phakathi kweentsimbi ezimbini okanye isinyithi kunye nesinyithi esingesiso.
Nqanda intsimbi engagqwaliyo ukuba ingagqwali:
Coca intsimbi engagqwaliyo rhoqo ukuze ususe izinto ezingcolisayo kwaye ugcine umaleko wayo okhuselayo.
Kuphephe ukuveza intsimbi engagqwaliyo kwiikloridi kunye neekhemikhali ezinobungozi.
Khusela intsimbi engagqwaliyo ekonakaleni koomatshini ngokusebenzisa iindlela ezifanelekileyo zokuphatha nokugcina.
Qinisekisa ukuba umoya ungena kakuhle kwiindawo apho kusetyenziswa khona intsimbi engatyiwayo ukugcina amanqanaba eoksijini.
Khetha intsimbi engagqwaliyo ekumgangatho ophezulu enomxube we-alloy ofanelekileyo olungiselelwe ukusetyenziswa.
