Iimveliso ezigqunywe nge-tantalum carbide zikonyusa njani ukuxhathisa kokubola kwemathiriyeli?

I-Tantalum carbide coating yitekhnoloji yonyango ehlala isetyenziswa ngaphezulu enokuphucula kakhulu ukuxhathisa kokubola kwezixhobo. I-Tantalum carbide coating inokuncanyathiselwa kumphezulu we-substrate ngeendlela ezahlukeneyo zokulungiselela, ezifana nokubekwa komphunga wekhemikhali, ukubekwa komphunga womzimba, ukutshiza, njl. indlela yokusingqongileyo, ngaloo ndlela iphucula ukuxhathisa umhlwa.

Ezi zilandelayo ziindlela ezininzi eziphambili zokugquma i-tantalum carbide ukomeleza ukuxhathisa kokutya:

1. Isiphumo sesithintelo sokwahlukaniswa:

I-Tantalum carbide coating inoxinano oluhle kunye nobunzima obuphezulu, obunokuthi ngokufanelekileyo ukwahlula i-substrate ekudibaneni nendawo yangaphandle kunye nokuthintela ukubola ngezinto ezinobungozi ezifana ne-asidi, i-alkali, kunye neetyuwa. I-dense barrier layer eyenziwe yi-tantalum carbide coating inokunciphisa ukunyanzeliswa komgangatho wezinto eziphathekayo kunye nokuthintela ukungena kwemithombo yeendaba ezonakalisayo, ngaloo ndlela iphucula ukuxhathisa kwe-corrosion.

2. Uzinzo kwiChemical:

I-Tantalum carbide coating inezinga eliphezulu lokuzinza kweekhemikhali kwaye inokugcina isakhiwo sayo kunye nokusebenza ngaphandle kweenguqu eziphawulekayo phantsi kweemeko ezingqongileyo. I-Tantalum carbide sisixhobo esine-inertness ephezulu yeekhemikhali enokumelana nokukhukuliseka kwemithombo yeendaba eyomeleleyo efana ne-acids, alkalis, kunye ne-oxidants. Ukongezelela, ngenxa yobunzima obuphezulu kunye ne-coefficient ephantsi ye-friction ye-tantalum carbide coeating, inokunciphisa ukungqubuzana kunye nokunxiba phakathi kwezinto eziphathekayo kunye nendawo yokusingqongileyo kunye nokwandisa ubomi benkonzo yezinto eziphathekayo.

3. Ukukwazi ukuzilungisa:

I-Tantalum kwi-tantalum carbide coating inekhono elithile lokuzilungisa. Xa i-coating ikrwelwe, igugile okanye yonakaliswe kancinci, i-tantalum inokusabela ngeoksijini, iklorini kunye nezinye izinto kwindawo emdaka ukwenza iikhompawundi ze-tantalum ezifana ne-tantalum oxide kunye ne-tantalum chloride, zizalise iziphene kumphezulu wokwaleka, kwaye kwakhona- yenza ifilimu ekhuselayo. Olu buchule lokuzilungisa lunokunciphisa ngokufanelekileyo inkqubo yokubola kunye nokulibazisa ukutshatyalaliswa kwengubo.

4. Ukuqhuba:

I-Tantalum carbide coating ine-conductivity enhle kwaye inokwenza umaleko wokukhusela we-electrochemical ukukhusela ukuhamba kwe-corrosion current. Xa umphezulu we-coating ugxunyekwe yi-corrosion medium, i-tantalum iya kubhengeza i-ion kwindawo ejikelezileyo ukuze yenze umahluko okhoyo ozinzileyo, uthintele ukuhamba kwe-corrosion current, kwaye ngaloo ndlela uthintele ukusabela kwe-corrosion.

5. Ukongezwa kwezongezo:

Ukuze kuphuculwe ngakumbi ukuxhathisa kwe-corrosion ye-tantalum carbide coating, izongezo zingongezwa ngexesha lenkqubo yokulungiselela ukutyabeka. Ngokomzekelo, ukongeza izongezo ezifana ne-potassium kunye ne-oxides kunokukhuthaza ukuxinana kunye nokucocwa kweenkozo zengubo, ukuphucula ukuzinza kwe-intercrystalline interface kwi-coating kunye nokukwazi ukuxhathisa i-discreteness, ngaloo ndlela kuphuculwe ukuxhathisa kwe-corrosion ye-coating.

Ngamafutshane, i-tantalum carbide coatings inokomeleza kakhulu ukuxhathisa ukubola kwezixhobo ngokusebenzisa iindlela ezinje ngesiphumo sothintelo lodwa, ukuzinza kweekhemikhali, ukukwazi ukuziphilisa, ukuqhuba kunye nokongeza okongeziweyo. Oku kunexabiso elibalulekileyo lesicelo kwiinkalo ezininzi, ezifana noshishino lweekhemikhali, amandla, i-aerospace, njl.
