Kromium Carbide Budada Alaabta Nadiifinta Sare
Sharaxaada Alaabta
Chromium carbide bir chromium (chromium trioxide) iyo kaarboonku waxay ku jiraan kaarboon ku jira faaruq.Qaabkeeda kelli waa Cr3C2 (miisaanka aragtida boqolkiiba kaarboon waa 13%), cufnaanta waa 6.2g/cm3 iyo engegnaanta ayaa ka sareysa HV2200.Muuqaalka budada carbide ee chromium waa cawl qalin ah.Chromium carbide budada waa meel dhalaalaysa sare walxo aan dabiici ahayn oo leh caabbinta xirashada wanaagsan, caabbinta daxalka iyo iska caabinta oksaydhka ee jawiga heerkulka sare (1000-1100 digrii).

Codsiga ugu muhiimsan
Lattice ee carbide chromium waa mid togan oo taban, oo leh dhibic dhalaalaysa 1895 ° C. Sababtoo ah sifooyinka wanaagsan ee caabbinta xirashada sare, caabbinta daxalka iyo iska caabinta heerkulka sare, waxaa inta badan loo isticmaalaa:
●Soosaarida alaabta alxanka gaarka ah, korantado taxane ah oo dusha sare ah, fiilooyinka qulqulka leh.
●Carbid cemented, ku daray Cr3C2 ee wax soo saarka ee carbide sibidhka ma sifayn karaa oo kaliya WC-daraha, laakiin sidoo kale hagaajinaysaa xoogga iyo adkaanta ee daawaha, oo si weyn u hagaajin karaa caabbinta daxalka ee daawaha.
● Qalabka buufinta kulaylka ah ee budada ah, oo ku salaysan Cr3C2 iyo ku darida Nicr superalloy budada alloy ee la warshadeeyay, iyadoo la adeegsanayo buufinta balaasmaha, waxay soo saari kartaa xirmooyin heer sare ah oo u adkaysta, daxalka u adkaysta, heerkul sare oo u adkeysi leh, oo si ballaaran loo isticmaalo marawaxadaha, shaabaduhu waa la jebiyey, Kuleyliyaha "afar tubo", iwm.
●Arc oo lagu buufiyay silig iyo silig tuubbada ah oo welded arc, siliga la buufiyay waxaa lagu daraa walxo Cr3C2, taas oo wanaajisa iska caabinta heerkulka sare iyo xirashada caabbinta.Waxaa loo adeegsadaa dayactirka iyo dayactirka ka-hortagga ee "afar tubbo" ee kuleyliyaha, iyo caabbinta-ka-hortagga dharka birta-samaynta ee warshadaha birta.Saxanka dahaarka ah, warshad koronto oo dhuxul shiidisa lacag, sababtoo ah isticmaalka Cr3C2 oo lagu daray ilaalinta fiilada alxanka tuubada, waxay si weyn u wanaajisaa nolosha adeegga.
