Tantalum carbide coating inowanzoshandiswa pamusoro pekurapa tekinoroji inogona kuvandudza zvakanyanya kusimba kwekupokana kwezvinhu. Tantalum carbide coating inogona kusungirirwa pamusoro peiyo substrate nenzira dzakasiyana dzekugadzirira, senge kemikari vapor deposition, muviri mhute deposition, sputtering, nezvimwewo, kugadzira yunifomu uye dense yekudzivirira layer, iyo inovhara zvinobudirira kubatana pakati pechinhu uye. iyo svikiro yezvakatipoteredza, nokudaro ichivandudza kudzivirira kwemarara.
Idzi dzinotevera nzira dzakati wandei dze tantalum carbide coating kuti iwedzere kuomarara kuramba kwezvinhu:
1. Isolation barrier effect: Tantalum carbide coating ine density yakanaka uye kuoma kwakanyanya, iyo inogona kunyatso bvisa substrate kubva pakubata nekunze svikiro uye kudzivirira ngura nezvinhu zvinoparadza zvakaita seasidhi, alkali, uye munyu. Iyo dense barrier layer inogadzirwa ne tantalum carbide coating inogona kudzikisa kupenya kweiyo zvinhu uye kudzivirira kupinda kweiyo corrosive media, nekudaro ichivandudza corrosion resistance yechinhu.
2. Kugadzikana kwemakemikari: Tantalum carbide coating ine kugadzikana kwemakemikari uye inogona kuchengetedza maitiro ayo uye kushanda pasina kuchinja kukuru pasi pemamiriro ezvinhu ezvakatipoteredza. Tantalum carbide chinhu chine yakakwira makemikari inertness iyo inogona kunyatso dzivirira kukukurwa kweiyo yakasimba corrosive media senge acids, alkalis, uye oxidants. Pamusoro pezvo, nekuda kwekuomarara kwepamusoro uye kuderera kwakadzika friction coefficient ye tantalum carbide coating, inogona zvakare kuderedza kukweshera uye kupfeka pakati pezvinhu uye svikiro rezvakatipoteredza uye kuwedzera hupenyu hwebasa rezvinhu.
3. Kugona kuzvigadzirisa: Tantalum mu tantalum carbide coating ine imwe yekuzvigadzirisa. Kana iyo yekupfeka ikakwenywa, yakasakara kana kukuvadzwa zvishoma, tantalum inogona kuita neokisijeni, chlorine uye zvimwe zvinhu mumhepo inoora kuti igadzire tantalum macompounds akadai setantalum oxide uye tantalum chloride, kuzadza zvikanganiso pamusoro pekupfeka, uye zvakare- gadzira firimu rinodzivirira. Uku kugona kuzvigadzirisa kunogona kunyatso kudzikamisa nzira yekuora uye kunonoka kuparadzwa kwejasi.
4. Conductivity: Tantalum carbide coating ine conductivity yakanaka uye inogona kuumba electrochemical protective layer kudzivirira kuyerera kwekuora ikozvino. Kana iyo yekumusoro yejasi yakasvibiswa neyakaora svikiro, tantalum ichaita adsorb ions munzvimbo yakatenderedza kuti iumbe yakagadzikana inogona mutsauko, kudzivirira kupfuura kwecorrosion ikozvino, uye nekudaro kudzivirira kuita ngura.
5. Kuwedzera kwezvinowedzera: Kuti uwedzere kunatsiridza kuputika kwekudzivirira kwetantalum carbide coating, additives inogona kuwedzerwa panguva yekugadzirira kwekuputira. Semuenzaniso, kuwedzera zvinowedzera zvakadai se potassium uye oxides zvinogona kusimudzira densification uye zviyo kunatsiridza kwejasi, kunatsiridza kugadzikana kweiyo intracrystalline interface mujasi uye kugona kurwisa discreteness, nekudaro kuvandudza kusimba kwekupotera kwejasi.
Muchidimbu, tantalum carbide coatings inogona kuwedzera zvakanyanya kushora kwemidziyo kuburikidza nemaitiro akadai seyega barriers athari, kugadzikana kwemakemikari, kugona kuzvirapa, conductivity uye kuwedzera kwekuwedzera. Izvi zvine kukosha kwekushandisa kwakakosha muminda yakawanda, senge indasitiri yemakemikari, simba, aerospace, nezvimwe.
