Chromium Carbide Foda Babban Mai Bayar da Tsafta
Bayanin Samfura
Chromium carbide karfe chromium (chromium trioxide) da carbon suna carbonized a cikin injin.Tsarin kwayoyin halittarsa shine Cr3C2 (kashi na ka'idar nauyin carbon shine 13%), yawancin shine 6.2g/cm3 kuma taurin yana sama da HV2200.Bayyanar chromium carbide foda ne azurfa launin toka. Chromium carbide foda ne babban narkewa batu inorganic abu da kyau lalacewa juriya, lalata juriya da hadawan abu da iskar shaka juriya a high zafin jiki yanayi (1000-1100 digiri).

Lattice na chromium carbide yana da kyau kuma mara kyau, tare da ma'anar narkewa na 1895 ° C. Saboda kyawawan halayensa na juriya mai girma, juriya na lalata da kuma yawan zafin jiki, an fi amfani dashi a:
●Manufacture na musamman waldi kayan, surfacing jerin lantarki, juyi-core wayoyi.
●Cermented carbide, ƙara Cr3C2 a cikin samar da siminti carbide ba zai iya kawai tace WC hatsi, amma kuma inganta ƙarfi da taurin na gami, da kuma iya muhimmanci inganta lalata juriya na gami.
●Thermal spraying foda abu, dangane da Cr3C2 da kuma ƙara Nicr superalloy zuwa sarrafa gami foda, ta yin amfani da plasma spraying, zai iya samar da high lalacewa-resistant, lalata-resistant, high-zazzabi resistant coatings, yadu amfani a fan ruwan wukake, like an karya, Boiler "tubu hudu", da dai sauransu.
●Arc fesa waya da submerged arc welded tubular waya, da baka fesa waya da aka kara da Cr3C2 abu, wanda inganta high zafin jiki juriya da kuma sa juriya.Ana amfani da shi wajen gyarawa da rigakafin rigakafi na "bututu huɗu" na tukunyar jirgi, da kuma jure juriya na tsagi na baƙin ƙarfe a cikin masana'antar ƙarfe.Rufe farantin, wutar lantarki injin niƙa azurfa, saboda amfani da Cr3C2 ƙara tubular walda waya surfacing kariya, ƙwarai inganta sabis rayuwa.
