Ubuvuzi bwa Surface kubifata: Ubuyobozi bwa tekinike

Hafi y'ibifunga byubucuruzi byose bikozwe mubyuma bya karubone, ibyuma bivanze, cyangwa ibyuma bidafite ingese. Ndetse iyo hakoreshejwe ibikoresho birwanya ruswa, kuvura hejuru bikomeza kuba ingirakamaro mu kuzamura uburebure bwa bolts nimbuto mubidukikije. Iyi ngingo irasesengura ibisanzwe hamwe nibisabwa, itanga injeniyeri nababikora ubushishozi bufatika kugirango imikorere yihuse.

1. Amashanyarazi ya Zinc (Amashanyarazi ya Zinc)

Amashanyarazi ya zinc nigikoresho gikoreshwa cyane kubucuruzi bwibyuma byubucuruzi bitewe nigiciro cyabyo kandi gihindagurika cyiza (kiboneka muri drab yumukara cyangwa olive). Ariko, itanga ruswa irwanya ruswa, mubisanzwe ikamara amasaha 72 mugupima umunyu utabogamye. Ikidodo kidasanzwe kirashobora kwongerera amasaha 200+, ariko inshuro 5-8 igiciro.

Intambamyi ikomeye ni hydrogène embrittlement, ishobora guteza intege imbaraga zikomeye (amanota 10.9 no hejuru). Guteka nyuma yisahani birashobora kugabanya ikwirakwizwa rya hydrogène, ariko inzira ntikunze gushyirwa mubikorwa kubera ibikorwa bigoye hamwe nigiciro. Ikigeretse kuri ibyo, ibyuma bifata ibyuma bya zinc byerekana ibipimo bya torque-mbere yo kubanziriza ibipimo, bigatuma bidakwiranye ningingo zikomeye. Amavuta nyuma yo kuvurwa arashobora kunoza ubudahwema ariko akongeraho ikiguzi.

2. Fosifati

Fosifati itanga uburyo buhendutse bwo guhinduranya zinc, nubwo irwanya ruswa. Imikorere iterwa cyane nubwiza bwamavuta nyuma yubuvuzi: amavuta asanzwe atanga amasaha 10–20 yumunyu wo gutera imiti, mugihe amavuta yo hejuru yongerera aya masaha 72-96 yikubye inshuro 2-3.

Ubwoko bubiri bwiganje mu gukoresha inganda:

• Finchating ya Zinc: Itanga amavuta meza yo guterana byoroshye.

• Fosifati ya Manganese: Ikomeye mu kurwanya ruswa, kwihanganira kwambara, no guhagarara neza (107–204 ° C / 225–400 ° F).

Fosifate yiziritse itoneshwa kubwizerwa bwa torque-to-preload ihoraho, bigatuma iba nziza kubiterane bikomeye nkibigize moteri (urugero, guhuza inkoni, imitwe ya silinderi) hamwe nu byuma byubaka. Ikigaragara ni uko fosifatique yirinda kwinjiza hydrogène, bigatuma ihitamo mbere yingufu zikomeye (urwego 10.9+).

3. Oxide Yirabura

Umwijima wa oxyde, ufatanije no gusiga amavuta, nuburyo bukoreshwa ningengo yimishinga ifata inganda. Nubwo igaragara neza iyo isizwe amavuta, irwanya ruswa irashobora kuba nto-kumara amasaha 3-5 gusa mugupimisha umunyu iyo amavuta amaze kwangirika. Guhora kwa Torque ni bibi, ariko gukoresha amavuta mugihe cyo guterana birashobora kugabanya ibi. Ikoreshwa ryibanze ryibanze muburyo budakomeye, buke buke.

4. Isahani ya Cadmium

Isahani ya Cadmium itanga imbaraga zidasanzwe zo kurwanya ruswa, cyane cyane mubidukikije byo mu nyanja. Nyamara, uburozi bwayo bwinshi hamwe nogutunganya amazi mabi bituma bihenze inshuro 15-20 kurenza plaque ya zinc. Imikoreshereze igarukira mu nzego zihariye nka peteroli yo mu mahanga hamwe n’indege zo mu mazi, aho imikorere yerekana ikiguzi.

5. Gushyira Chromium

Isahani ya Chromium itanga uburyo bwiza bwo gushushanya, gukomera, no kurwanya ubushyuhe (kugeza kuri 650 ° C / 1200 ° F). Nyamara, inganda zayo zikoreshwa ni nke kubera kugereranya ibiciro hamwe nicyuma kitagira umwanda hamwe ningaruka ziterwa na hydrogène. Mbere yo gushiraho umuringa na nikel ni ngombwa mu kurinda ruswa.

6.Ifeza & Nickel

• Gufata ifeza: Gukora nk'amavuta akomeye kandi birwanya ubushyuhe bukabije (kugeza kuri 871 ° C / 1600 ° F), bikarinda guhitanwa nubushyuhe bwinshi (urugero, ibyuma bifata ikirere). Inzitizi zibiciro akenshi zigabanya imikoreshereze yimbuto cyangwa utubuto duto.

• Isahani ya Nickel: Ihuza kurwanya ruswa hamwe nu mashanyarazi, nibyiza kubice nka terefone.

7. Ashyushye-Dip Galvanizing

Gushyushya ibishyushye birimo kwibiza muri zinc zashongeshejwe, bikabyara umubyimba mwinshi, urwanya ruswa (15-100 mm). Nyamara, umubyimba utaringaniye utoroshye urudodo rukwiranye, bisaba urudodo nyuma ya galvanizing gukora cyangwa imbuto nini cyane - byombi bikabangamira imbaraga. Inzira nayo yangiza ibidukikije kubera imyanda ya zinc hamwe n’ibyuka bihumanya. Ikigaragara ni uko bidakwiriye kwizirika mu cyiciro cya 10.9+ kubera ingaruka ziterwa nubushyuhe.

8. DacrometIgipfukisho

Dacromet®, tanga uburinzi bumwe ukoresheje matrise ya zinc-aluminium. Zikuraho hydrogène yinjira kandi zitanga urumuri ruhebuje, bigatuma biba byiza cyane-imbaraga-zikoreshwa cyane.

9.Abandi

Impuzu zihariye nka Magni (MAGNI), Ruspert (RUSPERT), hamwe na Hybride ya aluminium / Teflon ya Tiodize yujuje ibyifuzo byinshi, bitanga imbaraga zo kurwanya kwambara, gusiga amavuta, cyangwa kutagira imiti.

Ubuvuzi bwa Surface Kubyuma Byuma

• Gutesha agaciro: Ibyingenzi mugukuraho amavuta yo gukora yangiza imikorere nuburanga.

• Passivation: Yongera imbaraga zo kurwanya ruswa no kumurika hejuru yibiza mumashanyarazi ya nitric cyangwa citric aside.

• Gukwirakwiza amashanyarazi: Nikel cyangwa zinc zitemewe zitezimbere isura cyangwa itwara neza, nubwo ibyuma bitagira umwanda byangirika kwangirika akenshi bituma ibi bidakenewe.

Umwanzuro

Guhitamo uburyo bwiza bwo kuvura bisaba kuringaniza ruswa, imikorere yubukanishi, amabwiriza y’ibidukikije, nigiciro. Kuva kuri electroplated zinc kumateraniro yingengo yimari kugeza gukwirakwiza ubushyuhe bwa sisitemu zikomeye, buri buryo bukemura ibibazo byihariye. Ba injeniyeri bagomba gushyira imbere guhuza nibikorwa bikora - haba kurwanya amazi yumunyu, ubushyuhe bwinshi, cyangwa imitwaro ifite imbaraga - kugirango byihute kandi birambe.
