Metal MIM Surface Ukwelashwa

Isifinyezo seIzingxenye ze-Metal MIMInqubo Yokukhiqiza Nesicelo

IUkukhiqiza kwe-MIMinqubo ngokuvamile ihlanganisa: ukuxuba kanye granulation, umjovo ukubumba, degreasing, sintering, futhi ukucubungula yesibili.
(1) Izici zobuchwepheshe eziyinhloko zezingxenye ze-Metal MIM:

• 1. Ilungele ukwakhiwa kwezinto ezihlukahlukene zempushana, futhi umkhiqizo usetshenziswa kabanzi;
• 2. Izinga eliphezulu lokusetshenziswa kwezinto ezingavuthiwe nezinga eliphezulu lokuzishintshanisa kokukhiqiza, elilungele ukukhiqizwa ngobuningi okuqhubekayo.
• 3. Ingenza ngokuqondile izingxenye ezincane ezinezimo zejometri eziyinkimbinkimbi (0.03g ~ 200g);
• 4. Ukunemba kobukhulu bezingxenye kuphezulu (±0.1%～±0.5%), futhi ukuqedwa okungaphezulu kuhle (ukumahhadla 1～5μm);
• 5. Umkhiqizo unokuminyana okuphezulu okuhlobene (95-100%), ukuhlelwa okufanayo nokusebenza okuhle kakhulu;

Izinqubo ezimbalwa ezivame ukusetshenziswa ezingaphezulu zokwelashwa kwezingxenye ze-Metal MIM

Ipholishiwe
Ngokusebenzisa isenzo semishini, samakhemikhali noma se-electrochemical, ubulukhuni obungaphezulu be-workpiece buyancipha ukuze kutholwe indawo ekhanyayo neyisicaba.

I-Electroplating
Inqubo yokunamathisela ifilimu yensimbi ebusweni bensimbi noma enye into nge-electrolysis. I-Electroplating ingavimbela i-oxidation yensimbi (efana nokugqwala), ithuthukise ukumelana nokugqokwa, ukuguquguquka kukagesi, ukucubungula, ukumelana nokugqwala (i-sulfate yethusi, njll.) futhi ithuthukise ubuhle.

Ukwelashwa kwe-PVD
Ukusetshenziswa kwezinqubo zomzimba ukufeza ukudluliswa kwenqwaba, inqubo yokudlulisa ama-athomu noma ama-molecule ukusuka emthonjeni kuya ebusweni be-substrate. Umsebenzi wayo ukufafaza ezinye izinhlayiya ezinezakhiwo ezikhethekile amandla aphezulu, ukumelana nokugqoka, ukuchithwa kokushisa, ukumelana nokugqwala, njll.) ku-matrix ngokusebenza okuphansi, ukuze i-matrix ibe nokusebenza okungcono.

Ukuba mnyama
Kuyindlela evamile yokwelapha amakhemikhali ukukhiqiza ifilimu ye-oxide endaweni yensimbi ukuze ihlukanise umoya futhi ifinyelele injongo yokuvimbela ukugqwala. Lapho izidingo zokubukeka ziphezulu, ukwelashwa okumnyama kungasetshenziswa. Izingxenye eziyinhloko zoketshezi olumnyama yi-sodium hydroxide ne-sodium nitrite.

I-Phosphating

Kuyinqubo yokusabela kwamakhemikhali kanye ne-electrochemical ukwakha ifilimu ye-phosphate. Inhloso eyinhloko ye-phosphating yilokhu:

1) Ukuhlinzeka ngokuvikelwa kwesisekelo sensimbi futhi kuvimbele insimbi ukuthi ingagqwali ngezinga elithile;
I-2) Isetshenziswa njenge-primer ngaphambi kokudweba ukuze kuthuthukiswe ikhono lokunamathela kanye ne-anti-corrosion yefilimu kapende.
Futha ukwelashwa.

Kuyindlela yokwemboza ehlakazeka ibe amaconsi afanayo kanye namaconsi amahle ngokusebenzisa ingcindezi noma amandla aphakathi nendawo ngesibhamu se-spray noma i-atomizer ye-disc, futhi isetshenziswe ebusweni bento okumele ibe yijazi.
