1. UMUKARA
-----Umukara ni uburyo busanzwe bwo kuvura ubushyuhe bw'icyuma. Ihame ni ugukora agapira ka okiside ku buso bw'icyuma kugira ngo umwuka uvaneho kandi urinde ingese. Gutera umukara ni uburyo busanzwe bwo kuvura ubushyuhe bw'icyuma. Ihame ni ugukora agapira ka okiside ku buso bw'icyuma kugira ngo umwuka uvaneho kandi urinde ingese.
2.ZINC
——Electro-galvanizing ni ikoranabuhanga gakondo ryo gutunganya icyuma gikingira ibyuma ritanga ubushobozi bwo kwirinda ingese ku buso bw'icyuma. Ibyiza by'ingenzi ni ubushobozi bwo gusonerwa no kudakora neza. Bitewe n'ubushobozi bwacyo bwiza bwo gusiga amavuta, cadmium plating ikoreshwa cyane mu ndege, mu kirere, mu mazi, no mu bikoresho bya radiyo na elegitoroniki. Urupapuro rwo gusiga rurinda icyuma kirinda uburinzi bwa mekanike n'ubutabire, bityo ubushobozi bwacyo bwo kurwanya ingese ni bwiza cyane kuruta plating ya zinc.
3.HDG
——Ibyiza by'ingenzi ni ubushobozi bwo gusonerwa neza no kudakora neza. Bitewe n'ubushobozi bwayo bwiza bwo gusiga amavuta, cadmium plating ikoreshwa cyane mu ndege, mu kirere, mu mazi, no mu bikoresho bya radiyo n'ibikoresho by'ikoranabuhanga. Urupapuro rw'icyuma rurinda icyuma cya substrate haba mu kurinda ibyuma ndetse no mu buvuzi, bityo ubwiyongere bwacyo ni bwiza cyane kuruta plating ya zinc. Zinc ishyushye ifite ubushobozi bwo kurwanya ingese, irinda ibyuma, irwanya ikirere kibi, kandi irwanya isuri y'amazi y'umunyu. Ikwiriye inganda zikora imiti, inganda zitunganya ibintu ndetse n'inyubako zikorera ku nkombe no mu nyanja.
