Iriburiro ryubuhanga busanzwe bwo kubitsa amakoti akomeye

1. Ikoranabuhanga rya CVD

Ipitingi ikomeye cyane ni icyuma ceramic ceramic (TiN, nibindi), bigizwe nigikorwa cyicyuma mugutwikira hamwe na gaze ya gaze.Ubwa mbere, tekinoroji ya CVD yumuriro yakoreshejwe mugutanga imbaraga zo gukora reaction yo guhuza imbaraga nubushyuhe bwumuriro mwinshi wa 1000 ℃.Ubu bushyuhe burakwiriye gusa kubitsa TiN nibindi bikoresho bikomeye kubikoresho bya sima ya sima.Kugeza ubu, biracyari ikoranabuhanga ryingenzi kubitsa TiN-Al20 ibifuniko byuzuye kumutwe wibikoresho bya karbide.

2. Hollow cathode ion itwikiriye hamwe ninsinga zishyushye arc ion

Mu myaka ya za 1980, cohode cathode ion yubatswe hamwe ninsinga zishyushye arc ion coating zikoreshwa mukubitsa ibikoresho byo gutema.Ubu buryo bwombi bwa tekinoroji ya ion ni tekinoroji ya arc isohora tekinoroji, hamwe nicyuma cya ionisiyoneri igera kuri 20% ~ 40%.

3. Cathode arc ion

Kugaragara kwa cathodic arc ion coating byatumye habaho iterambere ryikoranabuhanga ryo kubitsa ibishishwa bikomeye.Igipimo cya ionisation ya cathodic arc ion coating ni 60% ~ 90%, ituma umubare munini wibyuma bya ion hamwe na ion ya reaction ya ion bigera hejuru yumurimo wakazi kandi bigakomeza ibikorwa byinshi, bikaviramo gushira no gushiraho imyenda ikomeye nka TiN.Kugeza ubu, tekinoloji ya cathodic arc ion ikoreshwa cyane cyane kugirango ibike imyenda ikomeye.

Inkomoko ya cathode arc nisoko ikomeye-ihumeka idafite pisine ihamye, kandi inkomoko ya arc irashobora gushyirwaho uko bishakiye, bikazamura igipimo cyo gukoresha umwanya wicyumba cyo gutwikamo no kongera ubushobozi bwo gupakira itanura.Imiterere ya cathode arc inkomoko irimo utuziga duto twa cathode arc inkomoko, inkingi arc inkomoko, hamwe nurukiramende ruringaniye runini arc isoko.Ibice bitandukanye byinkomoko ntoya ya arc, inkingi ya arc inkomoko, hamwe nisoko nini ya arc irashobora gutondekwa ukundi kugirango ubike ama firime menshi-na firime nano.Hagati aho, kubera igipimo cyinshi cya ionisiyoneri ya cathodic arc ion coating, ion yicyuma irashobora gukuramo imyuka myinshi ya reaction, bikavamo inzira nini kandi ikora byoroshye kugirango ibone impuzu nziza.Ariko, hariho ibitonyanga bitobito muri microstructure ya coating layer yabonetse na cathodic arc ion coating.Mu myaka yashize, tekinolojiya mishya myinshi yagaragaye kugirango itunganyirize imiterere ya firime, yazamuye ubwiza bwa firime ya arc ion.
