Yintoni uvavanyo lokutshiza ityuwa ngentsimbi?

Umhlwa kukutshatyalaliswa okanye ukuwohloka kwemathiriyeli okanye iipropathi zazo ezibangelwa kukusingqongileyo. Uninzi lwe-corrosion lwenzeka kwindawo ye-atmospheri. I-atmosfera ineenxalenye ezonakalisayo kunye nezinto ezonakalisayo ezifana neoksijini, ukufuma, utshintsho lobushushu kunye nezinto ezingcolisayo. Umhlwa wokutshizwa kwetyuwa yinto eqhelekileyo kunye neyonakalisayo emoyeni.

I-corrosion yetyuwa yokutshiza ebusweni bezinto zetsimbi kubangelwa ukusabela kwe-electrochemical phakathi kwe-ion ye-chloride equlethwe kwi-oxide layer kunye nokukhusela kwi-metal surface kunye nentsimbi yangaphakathi. Uvavanyo lokutshiza ityuwa yeemveliso zethu zemihla ngemihla zefenitshala yempahla yentsimbi lusekelwe kulo mgaqo kwaye isebenzisa indawo eyenziweyo eyenziwe ngezixhobo zokuvavanya ityuwa yokutshiza ukuze ibone ukuxhathisa komhlwa kwemveliso. Isiphumo sovavanyo sinokugwetywa ngokwepesenti kunye nokubonakala kwe-corrosion ye-hardware yefenitshala.

Phantsi kweemeko ezifanayo zovavanyo, ixesha elide eliseleyo kwisixhobo sovavanyo lokutshiza ityuwa, kokukhona ukuxhathisa komhlwa kwemveliso. Ngokomzekelo, i-electroplating ye-double-layer iqhutyelwa ngesiseko sokusebenzisa i-electroplating ephezulu, eyenza ukusebenza kwe-anti-rust kube ngcono.
