Entangawuuzi za siriimu ezisiba okutwalira awamu zikolebwa mu kyuma, ekimanyiddwa ennyo nga kaboni. Ekyuma kikuba ennyondo oba kikyusibwa, era langi yaakyo ey’obutonde eva ku kukola. Okuziyiza obusagwa, kyetaagisa okukozesa amasannyalaze. Kyokka, ekyuma ekitali kizimbulukuse-okutwala obuti, naye, tekyetaagisa kukola masannyalaze. Ku kyuma, langi y’amasannyalaze okutwalira awamu esalibwawo kasitoma, okusinziira ku langi gy’ayagala. Waliwo n’ebyetaagisa ku buwangaazi bw’okufuuyira omunnyo. Langi ezimu ezikola amasannyalaze zeetaaga okuwangaala okuwanvuwa okufuuyira omunnyo, ate endala zifuuse za buwuka mu ssaawa ntono. Ensonga endala eri nti oba kasitoma agenderera kufulumya kintu ekyo. Okutwalira awamu okutunda ebweru w’eggwanga kyetaagisa okusiiga ebizigo ebikuuma obutonde bw’ensi, ate ebimu mu ggwanga, ebimu bikola, naye ebisinga tebikola.
Electroplating esinga okukozesebwa mu self-okutwala entangawuuzi ku katale zinki etta obutonde, kuba esobola okugumira okukeberebwa okufuuyira omunnyo okumala essaawa 72, oba ennaku ssatu. Ekika kino eky’amasannyalaze kiwa obuwangaazi bw’okufuuyira omunnyo obuwanvu. Ng’ekyokulabirako, nickel enjeru erina obuwangaazi bw’okufuuyira omunnyo omumpi, ebiseera ebisinga efuuka enfuufu mu ssaawa ntono, tezisukka ssaawa 10. Naye ebimu ku bikozesebwa mu kukola ‘nickel’ ebyeru bisobola okusiigibwa amafuta, era ekiseera ky’okufuuyira omunnyo eky’entangawuuzi ezisiigiddwa amafuta kiyinza okuwanvuwa.
