- Tekinoroji yeCVD yekupisa
Machira akaomarara anowanzova machira esimbi eceramic (TiN, nezvimwewo), ayo anoumbwa nekuita kwesimbi mujira uye gasification inochinja. Pakutanga, tekinoroji yeCVD yekupisa yakashandiswa kupa simba rekuita reCombination reaction nesimba rinopisa pakupisa kwakanyanya kwe1000 ℃. Kupisa uku kunongokodzera kuisa TiN nedzimwe machira akaomarara pazvishandiso zvecarbide zvakasimwa. Kusvika pari zvino, ichiri tekinoroji yakakosha yekuisa machira eTiN-Al2O3 akasimwa pamisoro yezvishandiso zvecarbide zvakasimwa.
- Kuvhara ion ye cathode isina chinhu uye kuvhara ion ye arc yewaya inopisa
Mumakore ekuma1980, hollow cathode ion coating uye hot wire arc ion coating zvakashandiswa kuisa maturusi ekucheka akafukidzwa. Matekinoroji ese aya e ion coating matekinoroji ese ari maviri e arc discharge ion coating, ane chiyero chesimbi che ionization chinosvika 20% ~ 40%.
- Kuputira kweCathode arc ion
Kubuda kwe cathodic arc ion cating kwakatungamira mukuvandudzwa kwetekinoroji yekuisa machira akaoma pazviumbwa. Mwero we ionization we cathodic arc ion coating i60% ~ 90%, zvichibvumira huwandu hwakawanda hwe ions dzesimbi uye ma ions egasi reaction kusvika pamusoro pechinhu chebasa uye zvichiramba zvichiramba zvichishanda zvakanyanya, zvichikonzera kuiswa kwe reaction uye kugadzirwa kwemavara akaoma akadai seTiN. Parizvino, tekinoroji ye cathodic arc ion coating inonyanya kushandiswa kuisa machira akaoma pazviumbwa.
Nzvimbo ye cathode arc inzvimbo inobuda mvura yakasimba isina dziva rakanyungudutswa rakagadzika, uye nzvimbo yenzvimbo inogona kuiswa zvisina kurongeka, zvichivandudza mwero wekushandiswa kwenzvimbo yekamuri yekuputira uye kuwedzera kugona kwekutakura muchoto. Maumbirwo enzvimbo dze cathode arc anosanganisira nzvimbo diki dzakatenderera dze cathode arc, nzvimbo dze columnar arc, uye nzvimbo dzakakura dze arc dzakatetepa. Zvikamu zvakasiyana zvenzvimbo diki dze arc, nzvimbo dze columnar arc, uye nzvimbo hombe dze arc zvinogona kurongwa zvakasiyana kuti zviise mafirimu akawanda uye mafirimu e nano multilayer. Panguva imwecheteyo, nekuda kwehuwandu hwakawanda hwesimbi ye ionization ye cathodic arc ion coating, ma ions esimbi anogona kutora magasi akawanda e reaction, zvichikonzera huwandu hwakakura hwemaitiro uye kushanda kuri nyore kuti uwane ma coatings akaoma kwazvo. Zvisinei, kune madonhwe akaomarara mu micro-structure ye coatings layer inowanikwa ne cathodic arc ion coating. Mumakore achangopfuura, matekinoroji matsva mazhinji akabuda kuti anatse chimiro chefirimu layer, izvo zvakavandudza mhando yefirimu yekuputira arc ion.
