Ruitai Kitchen Knives: Yako Premier Source yeCustom Kitchen Knives Set kubva kuChina
Kune marudzi maviri eakajairwa maturusi ekuputira nzira: kemikari vapor deposition (cvd) uye yemuviri vapor deposition (pvd) parizvino. Mumakore achangopfuura, mamwe maitiro matsva ekuputira akaonekwa, ayo ane tarisiro yakanaka yekushandisa.
CVD
CVD nzira, inova yeatomic deposition, inzira yekugadzira yakasimba deposition layer pamusoro pekupisa matrix uchishandisa mhute, hydrogen uye mamwe makemikari esimbi halide pakupisa kwe950 ~ 1050 ℃. Maitiro acho anosanganisira matanho matatu: vaporization yezvinhu, kutakurwa kuenda kunharaunda yematrix uye kuumbwa kwekufukidza pamusoro pematrix.
Pakati pemhando dzese dzenzira dzecvd, vacuum ion bombardment uye magnetron ion reaction yekupfapfaidza ndiyo inonyanya kushandiswa. cvd tekinoroji inonyanya kushandiswa kupfekedza pamusoro pecemented carbide yekucheka maturusi, ayo akakodzera kumhanyisa roughing uye semi-kupedzisa yepakati uye inorema yekucheka.
Kuenzaniswa nedzimwe nzira dzekuputira, cvd nzira haina chete zvakanakira zvemidziyo yakapusa, yakakura maitiro, asi zvakare ine zvinotevera zvakanakira:
Kune marudzi akawanda ezviumbwa, zvinogona kuputirwa nesimbi, alloys, carbides, nitrides, borides, oxides, carbon nitrides, oxygen nitrides, hydro-carbon nitrides, nezvimwewo: Nekukwirira kwepamusoro uye kufanana, machira akawanda ane matishu akasiyana anogona kuwanikwa, uye ukobvu hwekuputira hwakafanana. Deposition rate yakakwira uye iri nyore kudzora. Iyo yekupfekedza ine kuchena kwakanyanya uye yakanaka uye dense zviyo. Kunamatira kwakasimba kunogona kuwana kukora kwakadzika. Mutengo wakaderera, wakakodzera kugadzirwa kwakawanda.
PVD
PVD nzira ndeyekubvisa zvinhu kubva kune zvakanangwa nemaitiro emuviri senge evaporation kana sputtering, uye wozoisa aya anesimba maion emhute pane substrate kana chikamu chepamusoro kugadzira firimu layer kuburikidza nevacuum kana semi-vacuum nzvimbo. Mhedzisiro yemhute yemaatomu esimbi akaputika kana akapfapfaidza inotungamira pakuiswa kwekomisheni inodiwa panzvimbo yemudziyo. pvd coating inogona kuputirwa netitanium nitride, titanium kabhoni nitride, aluminium titanium nitrogen makomponi, pamwe neakasiyana simbi anodzivirira ecarbides uye nitrides.
PVD tekinoroji inonyanya kushandiswa mukurapa kwepamusoro kweakabatanidzwa simende carbide maturusi uye yakakwira yekumhanya simbi maturusi. Yakave ichishandiswa zvakanyanya mukuvhara kurapwa kwecemented carbide bit, milling cutter, reamer, tap, yakakosha-yakaumbwa chishandiso, welding chishandiso uye zvichingodaro.
MT-CVD
Iyo tcn yakanamwa ine dense fibrous crystalline morphology inogona kuwanikwa nepakati tembiricha kemikari vapor deposition (MT-CVD) pa700 ~ 900 ℃. The coating ukobvu anogona kusvika 8 ~ 10μm, uye anogona kuva a2o3, tini pamusoro pemvura layer ne cvd teknolojia.
MT-CVD coating blade inokodzera kumhanya kukuru, tembiricha yakakwira, mutoro wakakura, mamiriro ekucheka akaomarara, hupenyu hwayo hunosvika zvakapetwa kaviri kupfuura hweakajairwa blade. cvd main drawback of the method is that deposition tembiricha yakakwira, uye mudziyo weannealing uye deformation uchaitika kana yakakwira yekumhanyisa chishandiso simbi simbi yakaputirwa. Saka mudziyo wakaiswa unofanira kudzimwa.
