Nzira dzakajairwa dzekuisa machira akaomarara

1. Thermal CVD tekinoroji

Mabatiro akaomarara anowanzo simbi eramic coatings (TiN, nezvimwewo), ayo anoumbwa nekuita kwesimbi mukuvhara uye reactive gasification. Pakutanga, iyo tekinoroji yeCVD tekinoroji yakashandiswa kupa iyo activation simba reCombination reaction nesimba rinopisa pakupisa kwakanyanya kwe1000 ℃. Iyi tembiricha yakakodzera chete kuisa TiN uye mamwe machira akaomarara pane esimende maturusi ecarbide. Kusvika pari zvino, ichiri tekinoroji yakakosha yekuisa TiN - Al2O3 composite coatings pamisoro yecarbide tool.

1. Hollow cathode ion coating uye inopisa waya arc ion coating

Muma1980, hollow cathode ion coating uye inopisa waya arc ion coating yakashandiswa kuisa maturusi ekucheka akavharwa. Ose ari maviri aya ion coating tekinoroji ndeye arc discharge ion coating tekinoroji, ine simbi ionization rate inosvika makumi maviri% ~ 40%.

1. Cathode arc ion coating

Kubuda kwecathodic arc ion cating kwakonzera kuvandudzwa kwetekinoroji yekuisa machira akaomarara pane mold. Iyo ionization rate yecathodic arc ion coating ndeye 60% ~ 90%, ichibvumira nhamba huru yeoni yesimbi uye reaction gasi ions kusvika pamusoro peiyo workpiece uye inoramba ichichengetedza basa rakakwirira, zvichiita kuti reaction deposition uye kugadzirwa kwemavara akaoma akadai seTiN. Parizvino, cathodic arc ion coating tekinoroji inonyanya kushandiswa kuisa machira akaomarara pane mold.

Iyo cathode arc sosi ndeye yakasimba-state evaporation sosi isina yakanyungudutswa dziva, uye iyo arc sosi nzvimbo inogona kuiswa zvisina tsarukano, ichivandudza chiyero chekushandiswa kwenzvimbo yekamuri yekuputira uye kuwedzera kurodha kwechoto. Maumbirwo emacathode arc masosi anosanganisira diki denderedzwa cathode arc masosi, columnar arc masosi, uye rectangular flat hombe arc masosi. Zvikamu zvakasiyana zvezvidiki zvearc masosi, columnar arc masosi, uye mahombe arc masosi anogona kurongwa zvakasiyana kuti aise akawanda-layer mafirimu uye nano multilayer mafirimu. Zvichakadaro, nekuda kweiyo yakakwira simbi ionization mwero wecathodic arc ion coating, simbi ions inogona kutora mamwe magasi ekuita, zvichikonzera kuwanda kwemaitiro uye kushanda kuri nyore kuwana yakanakisa yakaomeswa machira. Nekudaro, kune akakashama madonhwe mune iyo diki-chimiro cheiyo coating layer inowanikwa necathodic arc ion coating. Mumakore achangopfuura, matekinoroji mazhinji matsva akabuda kuti agadzirise chimiro cheiyo firimu layer, iyo yakavandudza kunaka kweiyo arc ion coating film.
