Metal MIM Surface Chithandizo

Chidule chaZigawo za Metal MIMNjira Yopangira ndi Kugwiritsa Ntchito

TheKupanga kwa MIMndondomeko zambiri zikuphatikizapo: kusakaniza ndi granulation, jekeseni akamaumba, degreasing, sintering, ndi processing yachiwiri.
(1) Zida zazikulu zamagawo a Metal MIM:

• 1. Ndizoyenera kupanga zipangizo zosiyanasiyana za ufa, ndipo mankhwalawa amagwiritsidwa ntchito kwambiri;
• 2. Mlingo wapamwamba wogwiritsa ntchito zida zopangira komanso kuchuluka kwazinthu zopangira zokha, zoyenera kupanga mosalekeza.
• 3. Ikhoza kupanga mwachindunji magawo ang'onoang'ono okhala ndi mawonekedwe ovuta a geometric (0.03g ~ 200g);
• 4. Kulondola kwa zigawozo ndipamwamba (± 0.1%～± 0.5%), ndipo mapeto ake ndi abwino (ovuta 1～5μm);
• 5. Mankhwalawa ali ndi kachulukidwe kakang'ono (95-100%), bungwe lofanana ndi ntchito zabwino kwambiri;

Njira zingapo zochizira pamwamba pa Metal MIM Parts

Wopukutidwa
Pogwiritsa ntchito makina, mankhwala kapena electrochemical zochita, kuuma kwapamwamba kwa workpiece kumachepetsedwa kuti apeze malo owala ndi ophwanyika.

Electroplating
Njira yolumikizira filimu yachitsulo pamwamba pa chitsulo kapena zinthu zina ndi electrolysis. Electroplating ingalepheretse makutidwe ndi okosijeni wachitsulo (monga dzimbiri), kupititsa patsogolo kukana, kuwongolera magetsi, kuwunikira, kukana dzimbiri (copper sulfate, etc.) ndikuwonjezera kukongola.

Chithandizo cha PVD
Kugwiritsa ntchito njira zakuthupi kuti akwaniritse kusamutsidwa kwakukulu, njira yosinthira ma atomu kapena mamolekyu kuchokera kugwero kupita kumtunda kwa gawo lapansi. Ntchito yake ndikupopera tinthu tating'onoting'ono tomwe timakhala ndi mphamvu zambiri, kukana kuvala, kutulutsa kutentha, kukana kwa dzimbiri, etc.) pa matrix omwe ali ndi magwiridwe antchito ochepa, kuti matrix azikhala bwino.

Kudetsa
Ndi njira yodziwika bwino yopangira mankhwala opangira filimu ya okusayidi pamtunda wachitsulo kuti isungunuke mpweya ndikukwaniritsa cholinga chopewera dzimbiri. Pamene zofunikira zowoneka sizikwera, chithandizo chakuda chingagwiritsidwe ntchito. Zigawo zazikulu za madzi akuda ndi sodium hydroxide ndi sodium nitrite.

Phosphating

Ndi ndondomeko ya mankhwala ndi electrochemical reaction kupanga phosphate filimu. Cholinga chachikulu cha phosphating ndi:

1) Perekani chitetezo kuzitsulo zoyambira ndikuletsa zitsulo kuti zisawonongeke pamlingo wina;
2) Amagwiritsidwa ntchito ngati choyambira asanapente kuti apititse patsogolo mphamvu zomata komanso zotsutsana ndi dzimbiri za filimu ya utoto.
Utsi mankhwala.

Ndi njira yokutira yomwe imamwazikana mu yunifolomu ndi madontho abwino pogwiritsa ntchito mphamvu kapena mphamvu ya centrifugal kupyolera mu mfuti ya spray kapena disc atomizer, ndipo imagwiritsidwa ntchito pamwamba pa chinthu chomwe chiyenera kuvala.
