Loluphi unyango olungaphezulu lokutsala iirivethi?

I-1.I-Zinc plating: i-zinc yokugqoka ifunyenwe ngesisombululo samanqaku;

I-2.Ipeyinti yokubhaka: Ipeyinti yokubhaka yipeyinti yepeyinti esetyenziswe kwi-surface ye-riveting body by thermal spraying technology.Umbala wepeyinti wee-rivets ezingaboniyo unokuba kwikhadi lombala we-RAI okanye unikezwe ngokwemfuno.

I-3.I-anodizing: i-anodizing yinkqubo yokugcoba isinyithi ngokuyibeka kwi-electrolyte njenge-anode kunye nokwenza ifilimu ye-oxidation kwi-metal surface.Ifilimu ye-anodized inomthamo ophezulu we-adsorption, ingaba unyango olunemibala, ukunamathela kombala kungcono kakhulu. ngaphezu kwepeyinti yokubhaka;
