Metal MIM Surface Treatments

Isishwankathelo seIzahlulo zeMetal MIMInkqubo yeMveliso kunye nesicelo

IUkwenziwa kweMIMinkqubo ngokubanzi ibandakanya: ukuxuba kunye granulation, naliti ukubumba, degreasing, sintering, kunye processing yesibini.
(1) Iimpawu eziphambili zobugcisa zeMetal MIM iinxalenye:

• 1. Ilungele ukwenziwa kwezinto ezahlukeneyo ze powder, kwaye imveliso isetyenziswa ngokubanzi;
• 2. Izinga eliphezulu lokusetyenziswa kwezinto eziluhlaza kunye neqondo eliphezulu lokuzenzekelayo imveliso, efanelekileyo kwimveliso yobuninzi eqhubekayo.
• 3. Inokwenza ngokuthe ngqo iindawo ezincinci ezinemilo yejometri enzima (0.03g ~ 200g);
• 4. Ukuchaneka kwe-dimensional kwamalungu kuphezulu (±0.1%～±0.5%), kunye nokugqitywa komphezulu kulungile (ubunzima 1～5μm);
• 5. Imveliso inobuninzi obuphezulu (95-100%), intlangano efanayo kunye nokusebenza okugqwesileyo;

Uninzi lweenkqubo zonyango oluqhele ukusetyenziswa kumphezulu weMetal MIM Parts

Ilungisiwe
Ukusebenzisa i-mechanical, ikhemikhali okanye isenzo se-electrochemical, uburhabaxa bendawo yokusebenza buncitshiswe ukufumana indawo eqaqambileyo kunye nesicaba.

Electroplating
Inkqubo yokudibanisa ifilimu yesinyithi kumphezulu wesinyithi okanye enye into nge-electrolysis. I-Electroplating inokuthintela i-oxidation yensimbi (efana nokugqwala), ukuphucula ukunyanzeliswa kokugqoka, ukuhanjiswa kombane, ukubonakalisa, ukuxhathisa ukubola (i-sulfate yethusi, njl.) kunye nokuphucula i-aesthetics.

Unyango lwePVD
Ukusetyenziswa kweenkqubo zomzimba ukuphumeza ukuhanjiswa kobuninzi, inkqubo yokudlulisa ii-athomu okanye iiathomu ukusuka kumthombo ukuya kumphezulu we-substrate. Umsebenzi walo ukutshiza ezinye iinqununu ezineempawu ezikhethekileyo amandla aphezulu, ukuxhatshazwa kokugqoka, ukutshatyalaliswa kobushushu, ukuxhathisa ukubola, njl.) Kwi-matrix kunye nokusebenza okuphantsi, ukwenzela ukuba i-matrix ibe nokusebenza okungcono.

Ubumnyama
Yindlela eqhelekileyo yonyango lweekhemikhali ukuvelisa ifilimu ye-oxide kwindawo yesinyithi ukuze ihlukanise umoya kwaye ifezekise injongo yokuthintela umhlwa. Xa iimfuno zokubonakala zingekho phezulu, unyango olumnyama lunokusetyenziswa. Amalungu aphambili olwelo olumnyama yi-sodium hydroxide kunye ne-sodium nitrite.

I-Phosphating

Yinkqubo yokusabela kweekhemikhali kunye ne-electrochemical ukwenza ifilimu ye-phosphate. Eyona njongo iphambili yephosphating kuku:

1) Ukubonelela ngokukhuselwa kwisiseko sesinyithi kunye nokukhusela isinyithi ukuba singabikho kumlinganiselo othile;
I-2) Isetyenziswe njenge-primer ngaphambi kokudweba ukuphucula ukunamathela kunye nokukwazi ukulwa ne-corrosion yefilimu yepeyinti.
Unyango lokutshiza.

Yindlela yokwaleka esasazwa kwiyunifomu kunye namathontsi acolekileyo ngendlela yoxinzelelo okanye amandla e-centrifugal ngompu wokutshiza okanye i-atomizer yediski, kwaye isetyenziswe kumphezulu wento yokubamba.
