Zida zosiyanasiyana ndi mankhwala awo pokonza, zoyendetsa, zosungirako, pamwamba pake zimakhala zosavuta kupanga kapena
kumamatira zinthu zakunja, monga machining burr, khungu la oxide, mafuta, ndi zina zotero, zonyansa zapamtundazi zidzakhudza kuphatikizika kwa zokutira ndi mphamvu yomangirira ndi matrix. Kuphimba koyambirira kwa mainThe Cholinga ndikuchotsa zinthu izi ndikuchita kutembenuka koyenera kwa mankhwala kuti apereke zoyenera Kupaka zofunikira za gawo lapansi, kuti awonjezere kumamatira kwa filimuyo, kutalikitsa moyo wautumiki wa filimuyo, Perekani kusewera kwathunthu kuchitetezo komanso kukongoletsa kwa zokutira.

Choncho, utsi zili pamaso processing. Zimaphatikizapo mbali zotsatirazi:

Degreasing pamaso ❖ kuyanika

Chitsulo ndi mbali zake mu ndondomeko yosungirako ndi zoyendera ntchito odana rust chitetezo mafuta, pepala zitsulo workpiece mu kujambula mafuta ayenera kugwiritsidwa ntchito pamene kuthamanga processing, mbali ayenera kukhudzana ndi emulsion pamene Machining, kutentha mankhwala angagwirizane kuzirala mafuta, pamene mbali zambiri amakhala ndi madontho mafuta ndi HanJi wa manja opareshoni, mafuta a mbali komanso zosafunika monga nthawi zonse ndi fumbi osakaniza mbali zonse za phosphorous, ndi fumbi osakaniza mbali zonse za phosphorous. filimu, komanso zimakhudza ❖ kuyanika ❖ kuyanika ntchito kukongoletsa ntchito ndi dzimbiri kukana Table 3-1 amatchula pretreatment osiyana ozizira adagulung'undisa zitsulo mbale. Zotsatira za zokutira za cathodic electrophoretic pakukana kwa dzimbiri.

Phosphating

Phosphating ndi njira yosavuta, yodalirika, yotsika mtengo komanso yosavuta kuti ipititse patsogolo kwambiri kukana kwa dzimbiri kwa zokutira zachitsulo. Amagwiritsidwa ntchito kwambiri kunyumba ndi kunja, makamaka popaka magalimoto, omwe amagwiritsidwa ntchito kwambiri m'zaka zaposachedwa. Pafupifupi 100% ya mbali woonda mbale mbale mu makampani galimoto ndi phosphating Phosphating ndondomeko amatanthauza zitsulo pamwamba kukhudzana ndi asidi njira munali dihydrogen mankwala mchere, mankhwala anachita ndi kwaiye mu zitsulo pamwamba bata la insoluble zolengedwa pawiri nembanemba wosanjikiza pamwamba mankhwala mankhwala njira ndi filimu kwaiye wotchedwa phosphating filimu.

Phosphate filimu mfundo

filimu ya phosphating inatha kupereka maziko oyenera kwambiri opaka utoto, chifukwa cha zotsatirazi:
1) Amapereka malo oyera, yunifolomu, opanda mafuta pamaziko a degreasing kwathunthu
2) kumawonjezera kumamatira kwa filimu organic ku gawo lapansi chifukwa cha thupi ndi mankhwala zochita Sikovuta kumvetsa kuti porous kapangidwe ka phosphating filimu kumawonjezera pamwamba pa gawo lapansi, kotero kuti malo kugwirizana pakati pa awiri amawonjezeredwa molingana, ndi opindulitsa permeability pakati pa zigawo ziwiri filimu kwaiye. Nthawi yomweyo, kuyanjana kwamankhwala pakati pa unsaturated resin ndi phosphate crystal kumapangitsanso mphamvu yake yomanga.
3) perekani wosanjikiza wosasunthika wosasunthika wodzipatula, pokhapokha kuwonongeka kwa ❖ kuyanika, kumakhala ndi ntchito yoletsa dzimbiri, makamaka kwa anode incision Mfundo yoyamba nthawi zambiri imanyalanyaza Pokhapokha kuti mafuta apangidwe bwino kwambiri kuti apange filimu yokhutiritsa ya phosphating Kotero filimu ya phosphating palokha ndiyomwe imakhala yodziwika bwino kwambiri ya pretreatment yodalirika ya teknoloji.
