Ukulawulwa komgangatho womgangatho wezinto zetsimbi

2.Ukuqhekeka: Izikhewu kumphezulu zinokubangela ukuphuka kunye nokungaphumeleli kwamacandelo, okuchaphazela kakhulu ubomi babo benkonzo.

I-3.I-Rust: Imingxuma emincinci okanye i-grooves eyenziwe yi-corrosion yomhlaba nge-oxidation, i-sulfurization, i-chlorination kunye nezinye izinto, ezichaphazela kakhulu ukusebenza kakuhle kunye nobomi bamacandelo.

I-4.I-Oxidation: Ifilimu ye-oxide emnyama eyenziwe yi-oxidation ebusweni ngokuqhelekileyo ivela kwindawo yokushisa ephezulu kunye nomswakama ophezulu, kwaye ifilimu ye-oxide kulula ukuwa.

5.Ukutshisa: ukutsha okumnyama okanye okumdaka kumphezulu okubangelwa kukusila ngokugqithisileyo okanye ukutshisa. Ukutshisa kuya kuchaphazela ngokunzulu ukuqina, ukuxhathisa ukunxiba kunye nokunganyangeki kwe-corrosion ye-part surface.
