Yenziwe ngentsimbi eshayinayoyaziwa ngokuxhathisa ukudleka kwayo, kodwa ayikhuselekanga ngokupheleleyo kumhlwa.Intsimbi engatyiwayo inokugqwala phantsi kweemeko ezithile, kwaye ukuqonda ukuba kutheni oku kusenzeka kunokunceda ukuthintela nokulawula ukurusa.
Intsimbi engatyiwayo inechromium, eyenza umaleko obhityileyo, owenziweyo weoksidi kumphezulu wayo xa ivezwe yioksijini.Lo maleko weoksidi, okwaziwa ngokuba "yi-passive layer," ibonelela ngokumelana nomhlwayenziwe ngentsimbi eshayinayoidume ngokuba.
Izinto ezichaphazela umhlwa kwintsimbi engatyiwayo:
Ukubonakaliswa kweChlorides
Ukonakala koomatshini
Ukunqongophala kweOxygen
Usulelo
Amaqondo obushushu aphezulu
Intsimbi eNgatyiwayo yoMgangatho ombi
Ubume beMichiza eNcinci
Iindidi zokuNjisa kweNsimbi eNgatyiwayo:
Kukho iintlobo ezahlukeneyo zentsimbi ye-corrosion.Ngamnye kubo uveza imingeni eyahlukeneyo kwaye ufuna ukuphathwa ngendlela eyahlukileyo.
Umhlwa ngokubanzi– 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.
Ukubola kombhobho– luhlobo lwendawo oluhlala kuyo olushiya imingxuma okanye imingxuma.Ixhaphakile kwiindawo ezinekloridi.
Umhlwa kwiCrevice– kwakhona umhlwa owenzeka kwintanda phakathi kwemiphezulu emibini edityanisiweyo.Ingenzeka phakathi kweentsimbi ezimbini okanye intsimbi kunye nengeyontsimbi.
Thintela intsimbi engatyiwa ngumhlwa:
Coca insimbi engenasici rhoqo ukuze ususe ukungcola kwaye ugcine umaleko wayo okhuselayo.
Kuphephe ukuveza intsimbi engatyiwayo kwiikloridi nakwiikhemikhali ezirhabaxa.
Khusela insimbi engenasici kumonakalo womatshini ngokusebenzisa iindlela ezifanelekileyo zokuphatha kunye nokugcina.
Qinisekisa umoya ofanelekileyo kwiindawo apho insimbi engenasici isetyenziselwa ukugcina amanqanaba oksijini.
Khetha umgangatho ophezulu wensimbi engenasici kunye nokwakheka kwe-alloy efanelekileyo kwisicelo esijoliswe kuyo.
