Zvigadzirwa zvakaputirwa netantalum carbide zvinosimudzira sei kuramba kwengura kwezvinhu?

Kuvhara kabhoni yeTantalum inzira inoshandiswa zvakanyanya pakurapa pamusoro pechinhu ichi inogona kuvandudza zvakanyanya kuramba kwengura kwezvinhu. Kuvhara kabhoni yeTantalum kunogona kunamirwa pamusoro pechinhu ichi kuburikidza nenzira dzakasiyana dzekugadzirira, dzakadai sekuiswa kwemvura yemakemikari, kuiswa kwemhepo yemuviri, kupwanya, nezvimwewo, kuti pave nechikamu chakafanana uye chakakora chekudzivirira, icho chinovhara kusangana pakati pechinhu chacho nenzvimbo yezvakatipoteredza, nokudaro zvichivandudza kuramba kwengura.

Zvinotevera nzira dzinoverengeka huru dzekugadzira tantalum carbide coating kuti zvinhu zvirambe zvichidzivirira ngura:

1. Mhedzisiro yekudzivirira kuparadzaniswa:

Kuvhara kweTantalum carbide kune huremu hwakanaka uye kuomarara kwakanyanya, izvo zvinogona kuparadzanisa substrate kubva pakubata nechinhu chekunze uye kudzivirira ngura nezvinhu zvinoparadza zvakaita seacids, alkalis, uye munyu. Chidziviriro chakasimba chinoumbwa nekuvhara kwetantalum carbide chinogona kuderedza kupenya kwechinhu uye kudzivirira kupinda kwezvinoparadza, nokudaro zvichivandudza kuramba kwengura kwezvinhu.

2. Kugadzikana kwemakemikari:

Tantalum carbide coating ine kugadzikana kwakanyanya kwemakemikari uye inogona kuchengetedza chimiro chayo uye mashandiro ayo pasina shanduko huru mumamiriro ezvinhu akaomarara ezvakatipoteredza. Tantalum carbide chinhu chine makemikari akawanda asina simba anogona kudzivirira kuparara kwemidziyo yakasimba inoparadza senge acids, alkalis, uye oxidants. Pamusoro pezvo, nekuda kwekuoma kwakanyanya uye kushoma kwekukweshana kwetantalum carbide coating, inogona zvakare kuderedza kukweshana nekupfeka pakati pechinhu chacho nenzvimbo yezvakatipoteredza uye kuwedzera hupenyu hwebasa rechinhu chacho.

3. Kugona kuzvigadzirisa:

Tantalum iri mu tantalum carbide coating ine kugona kwayo kuzvigadzirisa. Kana coating yacho ikakwenywa, yakasakara kana kuti yakakuvara zvishoma, tantalum inogona kusangana neokisijeni, chlorine nezvimwe zvinhu zviri mu corrosive medium kuti igadzire tantalum compounds dzakadai se tantalum oxide ne tantalum chloride, yozadza zvikanganiso zviri pamusoro pe coating, uye yogadzirazve firimu rekudzivirira. Kugona kwayo kuzvigadzirisa kunogona kunonoka corrosion procedure uye kunonotsa kuparadzwa kwe coating.

4. Kufambisa kwemhepo:

Kuputira kabhayidhi yeTantalum kune conductivity yakanaka uye kunogona kugadzira layer yekudzivirira electrochemical kudzivirira kuyerera kwe corrosion current. Kana pamusoro pe conductive pakanganiswa ne corrosive medium, tantalum inonyudza ma ions ari munzvimbo yakapoteredza kuti igadzire mutsauko wakasimba, kudzivirira corrosion current kupfuura, uye nokudaro kudzivirira corrosion reaction.

5. Kuwedzera kwezvinowedzera:

Kuti tiwedzere kuvandudza kuramba kwetantalum carbide coating, zvimwe zvinowedzerwa zvinogona kuwedzerwa panguva yekugadzirira coating. Semuenzaniso, kuwedzera zvimwe zvinhu zvakaita se potassium uye oxides kunogona kukurudzira densification uye grain fineness ye coating, kuvandudza kugadzikana kwe intracrystalline interface mu coating uye kugona kuramba kusiyanisa, nokudaro zvichivandudza kuramba kwe corrosion kwe coating.

Muchidimbu, machira etantalum carbide anogona kuwedzera zvakanyanya kuramba kwengura kwezvinhu kuburikidza nenzira dzakadai sekudzivirira kupatsanurwa, kugadzikana kwemakemikari, kugona kuzviporesa, kufambisa simba uye kuwedzera kwekuwedzera. Izvi zvine kukosha kwakakosha mumabasa mazhinji, akadai seindasitiri yemakemikari, simba, ndege, nezvimwewo.
