Chromium carbide hmoov yog cov khoom sib xyaw ua ke ntawm cov pa roj carbon thiab chromium, nrog rau lub cev thiab tshuaj lom neeg tshwj xeeb, thiab siv dav hauv cov ntaub ntawv hnav-resistant, cemented carbide, ceramics thiab lwm yam.Chromium carbide hmoov muaj cov yam ntxwv ntawm siab hardness, siab hnav tsis kam thiab kub stability.Vim nws cov hardness tsis tshua muaj siab, chromium carbide hmoov feem ntau siv rau hauv kev tsim cov khoom hnav-tiv taus thiab cov cuab yeej, xws li cov cuab yeej txiav, mining machinery thiab hnav-resistant conveying kav.Hauv thaj chaw ntawm carbide, chromium carbide hmoov tuaj yeem siv los tsim cov cuab yeej carbide thiab cov ntaub ntawv hnav-resistant.Chromium carbide hmoov kuj tuaj yeem siv rau hauv kev tsim cov raj kub kub, cov khoom siv hluav taws xob thiab cov reactors thiab lwm yam khoom siv tshuaj.Kev npaj ntawm chromium carbide hmoov yuav tsum tau kub siab synthesis technology, los ntawm kub melting thiab quenching txheej txheem txheej txheem.Cov hmoov no muaj cov khoom zoo thiab zoo dispersion, uas tuaj yeem txhim kho qhov hnav tsis kam thiab toughness ntawm cov khoom.

Lub lattice ntawm chromium carbide yog qhov zoo thiab qhov tsis zoo, nrog lub melting point ntawm 1895 ° C. Vim nws cov yam ntxwv zoo heev ntawm hnav tsis kam, corrosion kuj thiab kub tsis kam, nws yog tsuas yog siv nyob rau hauv:
● Tsim cov khoom siv vuam tshwj xeeb, surfacing series electrodes, flux-cored xov hlau.
●Cemented carbide, ntxiv Cr3C2 hauv kev tsim cov cemented carbide tuaj yeem tsis tsuas yog kho cov WC nplej, tab sis kuj txhim kho lub zog thiab hardness ntawm cov hlau, thiab tuaj yeem txhim kho corrosion kuj ntawm cov alloy.
●Thermal spraying hmoov cov ntaub ntawv, raws li Cr3C2 thiab ntxiv Nicr superalloy rau cov txheej txheem alloy hmoov, siv plasma spraying, tuaj yeem ua rau hnav-resistant, corrosion-resistant, high-temperature resistant coatings, dav siv nyob rau hauv kiv cua, seals yog tawg, Boiler "plaub raj", thiab lwm yam.
●Arc txau xaim thiab submerged arc welded tubular xaim, arc txau xaim ntxiv nrog Cr3C2 cov khoom, uas txhim kho qhov kub thiab txias tsis kam.Nws yog siv rau hauv kev kho thiab kev tiv thaiv kev saib xyuas ntawm "plaub kav" ntawm boiler, thiab hnav-tiv taus ntawm cov hlau ua cov ntaub zawj hauv kev lag luam metallurgical.Hauv ob sab phlu, fais fab nroj tsuag thee sib tsoo nyiaj, vim yog siv Cr3C2 ntxiv tubular vuam hlau surfacing tiv thaiv, zoo heev txhim kho lub neej kev pab cuam.
