Metal MIM Surface Treatments

Pfupiso yeMetal MIM ZvikamuKugadzira Maitiro uye Kushandisa

TheMIM kugadziramaitiro anowanzo sanganisira: kusanganisa uye granulation, jekiseni kuumba, degreasing, sintering, uye yechipiri kugadzirisa.
(1) Huru tekinoroji maficha eMetal MIM zvikamu:

• 1. Inokodzera kuumbwa kwezvinhu zvakasiyana-siyana zvehupfu, uye chigadzirwa chinoshandiswa zvakanyanya;
• 2. Kushandiswa kwepamusoro kwehuwandu hwezvigadzirwa uye huwandu hwepamusoro hwekugadzira automation, yakakodzera kuenderera mberi kwekugadzirwa kwehuwandu.
• 3. Inogona kuumba zvakananga zvikamu zviduku zvine maitiro akaoma ejometri (0.03g ~ 200g);
• 4. Kurongeka kwezvikamu zvezvikamu zvakakwirira (± 0.1%～± 0.5%), uye kupera kwepamusoro kwakanaka (kuoma 1～5μm);
• 5. Chigadzirwa chacho chine hukama hwepamusoro (95-100%), sangano rakafanana uye kushanda kwakanakisisa;

Akawanda anowanzo shandiswa pamusoro pekurapa maitiro eMetal MIM Zvikamu

Yakanatswa
Uchishandisa mechanical, kemikari kana electrochemical chiito, kushata kwepamusoro kwechishandiso kunoderedzwa kuti uwane nzvimbo inopenya uye yakadzikama.

Electroplating
Nzira yekubatanidza firimu resimbi pamusoro pesimbi kana zvimwe zvinhu ne electrolysis. Electroplating inogona kudzivirira simbi oxidation (senge ngura), kunatsiridza kusakara, magetsi conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) uye kuwedzera aesthetics.

PVD kurapwa
Iko kushandiswa kwemaitiro emuviri kuwana hukuru hwekufambisa, maitiro ekufambisa maatomu kana mamorekuru kubva kutsime kuenda pamusoro peiyo substrate. Basa rayo nderekupfapfaidza zvimwe zvimedu zvine akakosha zvimiro simba rakawanda, kupfeka kusagadzikana, kupisa kupisa, kushomeka kwemarara, nezvimwewo) pane matrix nekuita kwakaderera, kuitira kuti matrix iite zvirinani.

Blackening
Iyo yakajairika makemikari ekurapa nzira yekugadzira iyo oxide firimu pane simbi pamusoro kuparadzanisa mhepo uye kuzadzisa chinangwa chekudzivirira ngura. Kana izvo zvinodikanwa zvekutaridzika zvisiri kukwirira, kurapa kwakasviba kunogona kushandiswa. Zvikamu zvikuru zvemvura yakasviba ndeye sodium hydroxide uye sodium nitrite.

Phosphating

Iyo inzira yemakemikari uye electrochemical reaction kuumba phosphate firimu. Chinangwa chikuru chephosphating ndecheku:

1) Ipa dziviriro kune hwaro simbi uye kudzivirira simbi kubva pakuora kusvika pamwero wakati;
2) Inoshandiswa senge primer isati yapenda kuvandudza kunamatira uye anti-corrosion kugona kwefirimu repende.
Spray treatment.

Iyo inzira yekuputira iyo inoparadzirwa kuita yunifomu uye madonhwe akanaka nenzira yekumanikidza kana simba recentrifugal kuburikidza nepfuti yekupfapfaidza kana disc atomizer, uye inoshandiswa pamusoro pechinhu chinofanira kuva jasi.
