Ibifunga hafi ya byose bikozwe mubyuma bya karubone nicyuma kivanze, kandi biteganijwe ko ibyuma rusange birinda ruswa. Byongeye kandi, igifuniko cyo kuvura hejuru kigomba gukomera.
Kubijyanye no kuvura hejuru, abantu muri rusange bitondera ubwiza no kurinda ruswa, ariko umurimo wingenzi wibifunga ni uguhuza imiyoboro, kandi kuvura hejuru nabyo bigira uruhare runini mubikorwa byo kwizirika. Kubwibyo, mugihe duhitamo kuvura hejuru, tugomba nanone gutekereza kubintu byo kwizirika kumikorere, ni ukuvuga guhuza kwishyiriraho torque na preload.
1. Amashanyarazi
Gukwirakwiza amashanyarazi bisobanura ko igice cyiziritse kigomba gushyirwamo amashanyarazi cyinjijwe mumuti wihariye wamazi, uzaba urimo ibyuma byabitswe byabitswe, kuburyo nyuma yo kunyura mumuti wamazi hamwe numuyoboro, ibintu byicyuma mubisubizo bizagwa kandi bikomereze kubice byacengewe. Gukwirakwiza amashanyarazi muri rusange harimo gusya, umuringa, nikel, chromium, umuringa-nikel, nibindi.
2. Fosifati
Fosifati ihendutse kuruta gusya, kandi kurwanya ruswa kwayo ni bibi kuruta gusya. Hariho uburyo bubiri bukoreshwa bwa fosifate kubifata, fosifike ya zinc na fosifate ya manganese. Fosifike ya Zinc ifite amavuta meza kuruta fosifatiya ya manganese, na fosifati ya manganese ifite imbaraga zo kurwanya ruswa kandi ikarwanya kwambara kuruta gufata zinc. Ibicuruzwa bya fosifati nko guhuza inkoni nimbuto za moteri, imitwe ya silinderi, ibyuma byingenzi, ibimera biguruka, ibiziga byiziga nimbuto, nibindi.
3. Oxidation (umwirabura)
Kwirabura + amavuta ni igifuniko kizwi cyane kubifata inganda, kuko bihendutse kandi bisa neza mbere yo gukoresha lisansi. Kuberako umwijima udafite ubushobozi bwo kwirinda ingese, bizangirika vuba nyuma yubusa. Ndetse imbere yamavuta, ikizamini cyumunyu utabogamye gishobora kugera kumasaha 3 ~ 5 gusa.
4. Zinc zishyushye zinc
Gushyushya ubushyuhe ni ubushyuhe bwo gukwirakwiza ubushyuhe aho zinc ishyushya amazi. Ubunini bwacyo butwikiriye ni 15 ~ 100μm, kandi ntabwo byoroshye kugenzura, ariko bufite imbaraga zo kurwanya ruswa, bityo bukoreshwa kenshi mubuhanga. Bitewe n'ubushyuhe bwo gutunganya zinc-dip zinc, (340-500C) ntishobora gukoreshwa kubifata hejuru yicyiciro cya 10.9. Igiciro cya hot-dip galvanizing ya feri irarenze iya electroplating.
5. Gutera inda kwa Zinc
Kwinjiza Zinc ni metallurgical ikomeye yo gukwirakwiza ubushyuhe bwa powder ya zinc. Uburinganire bwabwo nibyiza, kandi nibice birashobora kuboneka mumutwe no kumyobo ihumye. Umubyimba wububiko ni 10 ~ 110μm, kandi ikosa rishobora kugenzurwa muri 10%. Imbaraga zayo zihuza hamwe nibikorwa byo kurwanya ruswa hamwe na substrate nibyiza mubyuma bya zinc (electro-galvanizing, hot-dip galvanizing na dacromet). Igikorwa cyacyo cyo kuyitunganya nta mwanda kandi cyangiza ibidukikije. Niba tudasuzumye chromium no kurengera ibidukikije, mubyukuri nibyiza cyane kubifata imbaraga nyinshi hamwe nibisabwa birwanya ruswa.
Intego nyamukuru yo kuvura hejuru yubuvuzi ni ugukora ibifunga kugira ubushobozi bwo kurwanya ruswa, kugirango byongere ubwizerwe no guhuza n'imikorere.
