Niobium Carbide
Kufotokozera
Niobium carbide, face centered cubic lattice, yokhala ndi utoto wofiirira, yosavuta kusungunuka mu titaniyamu carbide, zirconium carbide, tungsten carbide ndi mankhwala ena, komanso palimodzi kuti apange homogeneous olimba osakaniza. mtundu wa zinthu wokhala ndi mfundo yosungunuka kwambiri komanso kuuma kwakukulu. Amagwiritsidwa ntchito kwambiri muzowonjezera kutentha kwa refractory komanso zowonjezera za alloy.
Kugwiritsa ntchito
Refractory mkulu kutentha zipangizo ndi simenti zowonjezera carbide

Chofunika chapadera cha kukula ndi mankhwala akhoza kupangidwa |
Chifukwa Chosankha Ife:
1. Mutha kupeza zinthu zabwino kwambiri malinga ndi zomwe mukufuna pamtengo wotsika kwambiri.
2. Timaperekanso Reworks, FOB, CFR, CIF, ndi mitengo yobweretsera khomo ndi khomo. Tikukulangizani kuti mugwiritse ntchito zotumiza zomwe zingakhale zotsika mtengo.
3. Zipangizo zomwe timapereka ndizotsimikizika kotheratu, kuyambira pa satifiketi yoyeserera mpaka pagawo lomaliza.
4. e chitsimikizo kupereka yankho mkati 24hours(nthawi zambiri mu ola lomwelo)
5. Mutha kupeza njira zina zogulitsira, zoperekera mphero ndikuchepetsa nthawi yopanga.
6. Ndife odzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zomwe mukufuna mutapenda zonse zomwe mungasankhe, sitidzakusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino ndi makasitomala.
Chitsimikizo cha Ubwino (kuphatikiza zonse Zowononga ndi Zosawononga)
1. Mayeso a Visual Dimension
2. Kuwunika kwamakina monga kukhazikika, kutalika ndi kuchepetsa dera.
3. Kusanthula zotsatira
4. Kusanthula kwa mankhwala
5. Mayeso olimba
6. Kuyesa chitetezo cha pitting
7. Mayeso Olowera
8. Intergranular Corrosion Testing
9. Mayeso Olimba
10. Metallography Experimental Test
