Ifu ya Chromium Carbide Ifu Yinshi Itanga Isuku
Ibisobanuro ku bicuruzwa
Chromium carbide icyuma cya chromium (chromium trioxide) na karubone karubone mu cyuho.Inzira ya molekuline ni Cr3C2 (ijanisha ry'uburemere bwa karubone ni 13%), ubucucike ni 6.2g / cm3 kandi ubukana buri hejuru ya HV2200.Kugaragara kw'ifu ya chromium karbide ni ifu yifeza. Ifu ya karbide ya chromium nikintu kinini cyo gushonga ibintu bidafite imbaraga hamwe no kurwanya kwambara neza, kurwanya ruswa no kurwanya okiside mu bushyuhe bwo hejuru (dogere 1000-1100).

Umuyoboro wa karubide ya chromium ni mwiza kandi mubi, ufite aho ushonga wa 1895 ° C. Bitewe nibyiza biranga kwambara cyane, kurwanya ruswa no kurwanya ubushyuhe bwinshi, ikoreshwa cyane muri:
Gukora ibikoresho bidasanzwe byo gusudira, kugaragara hejuru ya electrode, insinga zifite amabara.
Carbide ya sima, wongeyeho Cr3C2 mugukora karbide ya sima ntishobora kunonosora ibinyampeke bya WC gusa, ariko kandi binatezimbere imbaraga nubukomezi bwumuti, kandi birashobora kunoza cyane kurwanya ruswa.
Material Ibikoresho byo gutera amashyanyarazi yubushyuhe, bishingiye kuri Cr3C2 no kongeramo Nicr superalloy kumashanyarazi yatunganijwe, ukoresheje spray ya plasma, birashobora kubyara imyenda irwanya kwambara, irwanya ruswa, irwanya ubushyuhe bwinshi, ikoreshwa cyane mubyuma byabafana, kashe ziravunika, Guteka "tebes enye", nibindi
● Arc yateye insinga hamwe na arc yarengewe na weld tubular, insinga ya arc yongewemo nibikoresho bya Cr3C2, biteza imbere ubushyuhe bwinshi kandi birwanya kwambara.Ikoreshwa mugusana no gukumira kubungabunga "imiyoboro ine" yo gutekesha, hamwe no kwihanganira kwambara imyenda ikora ibyuma munganda zikora ibyuma.Isahani yumurongo, uruganda rukora amashanyarazi rusya ifeza, kubera gukoresha Cr3C2 hiyongereyeho tubular welding wire surfacing kurinda, kuzamura ubuzima bwa serivisi.
