Monga gawo lalikulu-lokhala ndi gawo lamagalimoto, makina omanga ndi zida zina, ma wheel rim amakhudza kwambiri chitetezo ndi moyo wantchito. Komabe, monga ma gudumu amangokhalira kukumana ndi zovuta zakunja, amatha kugwa mvula ndi chipale chofewa, mvula yamchere, kuwala kwa UV komanso kuvala kwamakina, zomwe zimapangitsa kuti azikhala ndi dzimbiri komanso okosijeni. Izi sizimangokhudza maonekedwe awo komanso zimafooketsa kukhulupirika kwawo, zomwe zingayambitse ngozi zoopsa kwambiri. Chifukwa chake, kutetezedwa kwa dzimbiri kwa ma rimu a magudumu ndikofunikira kwambiri. Popanga ma wheel rim, ukadaulo wothana ndi-woletsa dzimbiri ndi chinthu chofunikira kwambiri komanso chofunikira kwambiri.
Kuwonongeka kwa magudumu a magudumu kumachitika makamaka chifukwa cha kuphatikiza kwachilengedwe ndi zinthu zomwe zimachitika mkati mwake. zinthu zachilengedwe monga mchere, chinyezi ndi mafakitale fumbi imathandizira zitsulo makutidwe ndi okosijeni; Pakadali pano, ma gudumu amapangidwa ndi aloyi ya aluminiyamu kapena chitsulo, zida zomwe zimakhala zosunthika komanso zomwe zimatha kuchita ndi zinthu zakunja. Chifukwa chake, makampani apanga makina oletsa-kuwononga dzimbiri omwe akugwira ntchito yonse-kuchokera ku kukhathamiritsa kwa zinthu mpaka kuchiritsa pamwamba-yomwe imayang'anira chitetezo ndi mtengo-mwachangu.
Kuphimba pamwamba ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri poteteza dzimbiri masiku ano. Mwa izi, ukadaulo wopaka ma electrophoretic umagwiritsa ntchito gawo lamagetsi kuwonetsetsa kuti utoto umakhala wofanana ndi gudumu pamwamba pa magudumu, ndikupanga filimu yoteteza. Zimapereka maubwino monga kumamatira mwamphamvu, kukana kwa dzimbiri komanso zokutira zofananira, kutsekereza zowononga zowononga monga madzi ndi mpweya. Ukadaulo wokutira ufa, Komano, umagwiritsa ntchito mfundo yomatira ma electrostatic kuti agwiritse ntchito utoto wofanana pamphepete mwa gudumu, womwe umachiritsidwa pakatentha kwambiri. Chokutira chake chimakhala cholimba kwambiri, chimatha-chosamva komanso sichimva ku UV-, kupangitsa kuti ikhale yoyenera kukwera mawilo agalimoto omwe amafunikira mawonekedwe apamwamba komanso otetezedwa.
Electroplating ndi njira yofunika kwambiri yotetezera ma gudumu kuti asawonongeke, makamaka kuphatikiza njira monga chrome plating ndi zinc plating. Chrome plating imapanga mapeto owala, owoneka bwino omwe amaphatikiza kusachita dzimbiri ndi kukongoletsa kokongola, ndipo amagwiritsidwa ntchito mofala-pamalire akumapeto; Zinc plating, komano, imagwiritsa ntchito mfundo yoteteza anode yopereka nsembe, momwe ngakhale zokutira zitawonongeka, zosanjikiza za zinki zimawononga kaye, potero zimateteza maziko a gudumu. Izi zimapangitsa kuti ikhale yoyenera zitsulo zamagudumu zomwe zimagwiritsidwa ntchito m'madera ovuta, monga omwe amapezeka m'makina omanga.
Kuphatikiza pa chithandizo chapamwamba, kukhathamiritsa kwa zinthu ndi njira zosindikizira zimathanso kukulitsa kukana kwa dzimbiri. Kugwiritsa ntchito dzimbiri-zosakaniza zosagwira, monga ma aluminiyamu aloyi ndi zitsulo zosapanga dzimbiri, zingachepetse kuopsa kwa dzimbiri komwe kumayambira; zosindikizira pamphambano zapakati pa magudumu, matayala ndi machubu amalepheretsa kuti chinyezi ndi mchere zisalowe m'mipata, potero zimachepetsa dzimbiri. Kuphatikiza apo, kukonza nthawi zonse, monga kuyeretsa ndi kuthira phula, kungathenso kutalikitsa moyo wa wheel rim's anti-corrosion coating.
Ndi kupita patsogolo kwa umisiri wamafakitale, ukadaulo wa wheel rim anti{0}}corrosion technology ukupita patsogolo kuti ukhale wosasunthika, wochita bwino komanso wokhalitsa. Kugwiritsa ntchito zinthu zatsopano zotchinjiriza zachilengedwe-zopaka zokometsera bwino komanso zomatira zophatikizika sikungowonjezera chitetezo komanso kumachepetsa kuwononga chilengedwe. M'tsogolomu, kudzera m'magulu opanga zinthu za digito ndi mwanzeru, ukadaulo woletsa{4}kuwononga dzimbiri udzakhala wolondola komanso wokhazikika, zomwe zikupereka chitetezo chodalirika komanso chanthawi yayitali-chitetezero chosatha cha ma wheel rim m'malo osiyanasiyana.
