Sezvatinoziva tese, nzira dzinowanzoshandiswa mukuputira vacuum kufefeterwa uye ion sputtering. Ndeupi musiyano uripo pakati pe transpiration coating uye sputtering coating Vazhinjivanhu vane mibvunzo yakadai. Ngatitaurei nemi mutsauko pakati pe transpiration coating ne sputtering coating
Vacuum transpiration firimu ndeyekupisa iyo data kuti ive yekufambisa kune yakagadziriswa tembiricha nenzira yekupikisa kupisa kana electron danda uye laser shelling munzvimbo ine vacuum degree isingasviki 10-2Pa, kuitira kuti thermal vibration simba remamorekuru kana. maatomu ari mudata anodarika simba rinosunga repamusoro, zvekuti mamorekuru mazhinji kana maatomu anofema kana kuwedzera, uye anoaisa zvakananga pane substrate kuti agadzire firimu. Ion sputtering coating inoshandisa iyo yakakwira remonstrance kufamba kwemaion akanaka anogadzirwa nekubuda kwegasi pasi pesimba remagetsi kubhomba chinangwa se cathode, kuitira kuti maatomu kana mamorekuru ari muchinangwa anopukunyuka uye anoisa pamusoro pechishandiso chakapfava kuti aumbe. firimu rinodiwa.
Iyo inonyanya kushandiswa nzira yevacuum transpiration coating ndeye kuramba kupisa nzira. Zvakanakira iyo iri nyore chimiro chekudziya sosi, yakaderera mutengo uye nyore kushanda. Zvayakaipira ndezvekuti haina kukodzera simbi dzinoramba uye tembiricha inodzivirira midhiya. Electron danda kudziyisa uye laser kudziyisa anogona kukurira kuipa kwekupokana kupisa. Mukudziya kwe electron beam, iyo yakatarisana ne electron danda inoshandiswa kupisa zvakananga data rakavharwa, uye kinetic simba re electron beam rinova simba rekupisa kuita kuti data rifambe. Laser kudziyisa kunoshandisa yakakwirira-simba laser sosi yekudziya, asi nekuda kwemutengo wakakwira we-laser-simba, inogona kushandiswa chete munhamba shoma yemarabhoritari ekutsvagisa.
Sputtering hunyanzvi hwakasiyana nehunyanzvi hwekuita vacuum transpiration. Sputtering (Sputtering) zvinoreva chiitiko chinochaja zvimedu zvinobhomba kumashure (chinangwa) chemuviri, zvekuti maatomu akasimba kana mamorekuru anoburitswa kubva pamusoro. Zvizhinji zvezvimedu zvinobudiswa ndezveatomu, iyo inowanzonzi maatomu akaparara. Maputtered particles anoshandiswa kugadzira zvibodzwa anogona kuve maerekitironi, maion kana mativi asina kwaakarerekera. Nekuti maion ari nyore kuwana iyo kinetic simba rinodiwa pasi pemunda wemagetsi, maion anonyanya kusarudzwa semashelling particles.
Iyo sputtering process inoenderana nekupenya kwekubuda, ndiko kuti, maion ekupuruzira anobva pakubuda kwegasi. Unyanzvi hwakasiyana hwekupfira hune nzira dzakasiyana dzekuburitsa kupenya. DC diode sputtering inoshandisa DC glow discharge; Triode sputtering imvura inopenya inotsigirwa necathode inopisa; RF sputtering inoshandisa RF glow discharge; Magnetron sputtering inopenya inodzorwa ne annular magnetic field.
Kuenzaniswa nevacuum transpiration coating, sputtering coating ine zvakawanda zvakanaka. Kana chero chinhu chinogona kusapurwa, kunyanya maelementi nemakomisheni ane nzvimbo yakakwira yekunyungudika uye kuderera kwemhute; Iko kunamatira pakati pefirimu yakasvibiswa uye substrate yakanaka; High film density; Ukobvu hwefirimu hunogona kudzorwa uye kudzokorora kwakanaka. Izvo zvisingabatsiri ndezvekuti michina yakaoma uye inoda ma-high-voltage madivayiri.
Pamusoro pezvo, musanganiswa wenzira yekufambisa uye nzira yekupopota ndeye ion plating. Zvakanakira nzira iyi ndeyekunamatira kwakasimba pakati pefirimu uye substrate, yakakwirira deposition rate uye yakakwirira density yefirimu.
