Mukugadzirwa kwemaindasitiri kuripo, maitiro ekupukuta simbi isina ngura akakamurwa kuita zvikamu zvina: kupukuta kwemuchina, kupukuta kwemakemikari, kupukuta kwemagetsi, uye kupukuta kwemvura. Nheyo uye hunhu hwekushanda kwemaitiro ega ega zvinosiyana zvakanyanya, zvinoda kusarudzwa kwakanyatsojeka zvichibva pachimiro chechigadzirwa, giredhi rezvinhu, uye zvinodiwa pakushandisa. Mune zvimwe zviitiko, "maitiro emusanganiswa" (akadai sekupukuta kwemuchina + kupukuta kwemagetsi) anoshandiswa kuvandudza kushanda zvakanaka uye kushanda zvakanaka.
Kupukuta Nemuchina: Nheyo yekupukuta nemuchina inosanganisira kushandisa zvishandiso zvakaita semavhiri ekukuya, mavhiri efaibha, uye mavhiri emvere pamwe chete neabrasives kucheka pamusoro pesimbi isina ngura. Zvikanganiso zvinobviswa zvishoma nezvishoma uye kuomarara kwepamusoro kunoderedzwa kuburikidza nekupukuta nehasha, kupukuta nepakati, uye kupukuta netsvina. Pfungwa huru dzekushanda: Kupukuta nehasha kunoshandisa vhiri rekukuya rine 80-120 grit kubvisa mavanga emuchina; kupukuta nepakati kunoshandisa vhiri refaibha rine 400-800 grit kunatsa pamusoro; uye kupukuta nehasha kunoshandisa paste yekupukuta nedhaimani pamwe chete nevhiri remvere kuti ipedzise kupenya kwakanyanya. Mukati mekuita uku, kumhanya nekumanikidzwa zvinofanirwa kudzorwa kudzivirira kupisa kwakanyanya kunogona kutungamira mukushanduka kwesimbi. Mabhenefiti nemiganhu: Mutengo wakaderera, kugona kudzora zvakanyanya, kwakakodzera ese magiredhi esimbi isina ngura; zvisinei, ine kushanda kwakaderera kwekupukuta kwezvivakwa zvakaoma (senge maburi emukati, shinda, uye misoro ye tee) uye inowanzoitika mukukanganisa kwevanhu. **Zviitiko Zvinoshanda:** Zvigadzirwa zvesimbi isina ngura zvakati sandara uye zviri nyore, zvakaita semaplate esimbi isina ngura, mavharuvhu, mapipe fittings, uye mapaneru ekuvaka.
**Kupolisha Kwemakemikari:**
**Nheyo:** Ichishandisa hunhu hwekunyungudika kwemusanganiswa we nitric acid-hydrofluoric acid, inonyanya kukanganisa maburi madiki ari pamusoro pesimbi isingatsvedzeri, zvichiita kuti pamusoro payo pave panyoro. Hapana magetsi kana michina yakaoma inodiwa.
**Maitiro Ekushanda:** Dzora zvakasimba chiyero chemushonga wekupukuta (wedzera 5-10% glycerin kudzivirira ngura yakawandisa) uye tembiricha (60-80℃). Sukurudza nekukurumidza nemvura yakabviswa maion mushure mekupukuta uye bvisa acid yakasara ne sodium bicarbonate solution.
**Zvakanakira Nezvisingaitwe:** Inogona kugadzirisa maworkpiece akawanda panguva imwe chete, inoshanda zvakanyanya, inodhura zvishoma, yakakodzera zvikamu zvakatetepa uye zvivakwa zvakaoma; zvisinei, kurapwa kwemvura inopolisha marara kunodhura, uye zvakaoma kudzora kufanana kwenzvimbo dzakaoma.
**Zvinhu Zvinoshanda:** Kugadzirwa kukuru kwezvikamu zvidiki, zvakaoma, zvakaita sezvisungo zvesimbi isingatsvi, zvinhu zvepombi diki zvakanyatsogadzirwa, uye zvimwe zvekushandisa mukicheni.
**Kupolisha Kwemakemikari:** Kupolisha Kwemagetsi
Nheyo: Kushandisa simbi isina ngura seanode, magetsi anopfuudzwa ne phosphoric acid-sulfuric acid electrolyte. Uchishandisa nheyo ye "electrochemical anodic dissolving," huwandu hwemagetsi ari pamusoro pemvura hunowedzerwa, zvichikonzera kunyungudika nekukurumidza uye microscopic leveling, ukuwo uchigadzira dense passivation layer. Pfungwa Huru dzeKushanda: Dzora tembiricha ye electrolyte kusvika 55-60℃, huwandu hwemagetsi kusvika 15-50 A/dm², uye nguva yekupukuta kusvika 5-10 maminetsi. Kurapa kwe nitric acid passivation kunotevera kunodiwa kuti uwedzere kuramba ngura. Mabhenefiti uye Miganhu: Kunyatso pukuta kwakanyanya, nekuomarara kwenzvimbo kusvika pasi peRa0.05μm, uye kuramba ngura kwakanyanya zvichienzaniswa nekupukuta kwemuchina; zvisinei, mari yakawanda yekudyara uye kushanda kwehunyanzvi zvinodiwa, zvikasadaro kusiyana kwengura neruvara kunogona kuitika. Mamiriro Anoshanda: Zvigadzirwa zvine zvinodiwa zvakasimba zvekudzivirira ngura uye kupera kwenzvimbo, zvakaita semidziyo yekurapa, michina yechikafu, michina ye vacuum, uye mapaipi emakemikari akakodzera.
Kupukuta Kwemvura
Musimboti: Kushandisa pombi ine simba guru kuendesa mvura inobaya (silicon carbide powder + polymer medium), kucheka nemicroscope kunowanikwa nekuyerera pamusoro pebasa. Iyi tekinoroji "inochinjika yekupukuta". Pfungwa Huru dzeKushanda: Sarudza saizi yegrit inobaya zvichienderana nedhayamita yegomba rebasa uye chimiro charo, uye dzora kumanikidzwa kwekupomba uye mwero wekuyerera. Iyo inobaya inogona kudzokororwa. Zvakanakira uye Zvipingamupinyi: Inogona kukunda makona akafa asingakwanise kusvika maitiro echinyakare, akadai semakomba emukati, makomba anopindirana, uye makomba asingaonekwe; zvisinei, nguva yekugadzirisa yebasa rimwe chete yakareba, zvichiita kuti ive yakakodzera zvikamu zvidiki zvezvikamu zvakanyatsonaka. Mamiriro Anoshanda: Kupukuta zvikamu zvakaoma zvechimiro zvakaita sema tee esimbi isina ngura, mapipe emukati akanyatsonaka, uye hydraulic valve sleeves.
Uyezve, kupukuta simbi isina ngura kunoita kuti pave nemhando dzakasiyana dzepamusoro, dzakadai se2D (matte), 2B (smooth matte, inonyanya kushandiswa), BA (high gloss), Nhamba 4 (uniform reflective), HL (brushed), uye Nhamba 8 (girazi). Mhando dzakasiyana dzinoenderana nekubatanidzwa kwakasiyana kwemaitiro ekupukuta uye zviratidzo zvakakosha zvemhando yezvigadzirwa mukugadzirwa kwemaindasitiri.
