Nyochaa nke Turgo Carbide

Tingsten Carbide, WC, ma ọ bụ Tungsten Sumicarbide, W2C, bụ onyinye kemịkalụ nwere Tuststen na carbon, yiri titanium Carbidi. A na-akpọkarị carbide na-akpakọrịta.

Ngwongwo kemịkalụ

E nwere ogige mara mma nke Tungsten na carbon, wc na w2c. Ma ogige abụọ ahụ nwere ike ịnọ na mkpuchi na oke nwere ike ịdabere na usoro mkpuchi, lee dịka eg

Enwere ike ịkwadebe WC site na mmeghachi omume nke Tungsten Metal na carbon na 1400-29. Uzo ndi ozo gunyere usoro ihe ndina nke patters nke na - emeghachi ma obu igwe anụnụ anụnụ WO3 na ngwakọta CO3 na CO / COE2. Chectotion Vapo nedozi ego nke enyochala:

Tygogen hexachloride na hydrogen, dị ka ibelata onye nnọchite na methane dị ka isi iyi carbon na 670'c

WCLQ + H2 + CH4 → WC + 6HCL

na-emegharị Turgogen Hexafluoride na hydrogen dị ka onye na-ebelata na methanol dị ka isi carbon na 350'c

WF6 + H2 + Ch3OH → WC + 6HF + H2O

Na oke okpomọkụ wc decompos na tungsten na carbon na nke a nwere ike ime n'oge okpomọkụ okpomọkụ dị elu velocity feelma (HVOF) na elu plasma (HEP).

Oxiding nke WC na-amalite na 500-600'c.it na-eguzogide ọgwụ acid ma ọ bụ naanị site na hydric acid (hno / hno / hno / hno3) dị n'elu ụlọ. [2] Ọ na-emeghachi omume na ikuku gas na ụlọ okpomọkụ na chlorine n'elu 400'c ma na-agụgharị ka ọ na-agbaze.

WC enyochala maka ike ya dị ka onye na-ahụ maka ya na oxygen na oxygen na-emepụta mmiri site na hydrogen na ọnụnọ mmiri, na ivu nke 2,2-dimethylpropane ka 2-methybutane. A tụrụ ya ka ọ bụrụ onye nnọchi maka Iridium na-agabiga na mmiri hydrazine siri ike na-akpachara anya.

Enwere ụdị WC, ụdị hexagotal, α-wc, na ụdị ọnọdụ okpomọkụ dị elu, β-wc, nke nwere usoro nnu nnu. Enwere ike ilele ụdị hexagonal dị ka nke na-eme ka ọ na -echeta akwa nke ọla eji eme ya, na carbon na carbon na carbon enwere ike kpebie ụdị nkekọ na-esonụ; Oghere dị n'etiti ụyọkọ tumsten na-ebuso oyi akwa bụ 291pm, dị mkpụmkpụ n'etiti ụyọkọ tumsten bụ 285 carbon ogologo bụ 220 PM.
