Ingaruka zo kuvura cryogenic kumiterere ya karbide ya sima

Ibikoresho bya mashini yaCarbidebigaragarira cyane cyane mubukomere, imbaraga zoroshye, imbaraga zo kwikuramo, gukomera kwingaruka, imbaraga zumunaniro, nibindi.

Niba kuvura cryogenic bishobora guteza imbere imiterere ya karbide ya sima ni uburyo bwimbitse bwerekana imikorere yubuhanga bwo kuvura cryogenic.Liu Yajun n'abandi.yakoze ubuvuzi bwa cryogenic kuri YW1karbide.Ibisubizo byerekanaga ko nyuma yo kuvura cryogenic, microhardness yiki kirango cyakarbideibyuma byiyongereye kuva 1764HV bigera kuri 2263.7HV, naho ubukana bwa Rockwell bwiyongereye kuva 90HRA bugera kuri 92HRA.Jiang n'abandi.yashyize karbide ya YG8 ya sima mu bushyuhe buke bwa 77K kugirango ivurwe kandi isanga ubukana bwayo nimbaraga zo kwikuramo byiyongereyeho 4.9% na 10.1%.

Chen Zhenhua n'abandi.yabonye kandi ibisubizo bisa nyuma yo kuvura cryogenic yo murwego rumwe rwaCarbide.Zhang Pingping yashyize YG6X karbide nziza cyane ya sima ya sima mu isanduku ya kirogenike kugira ngo avurwe kandi asanga imbaraga zayo zunama n'imbaraga zo guhatira ziyongereyeho 7,6% na 10.8%.Chen Hongwei yabanje gukonjaYG15 yashimangiye karbidehanyuma ukayinjiza muri azote yuzuye kugirango ivurwe.Ibisubizo byerekanaga ko ugereranije na mbere yo kuvura cryogenic, imbaraga zo kugonda zaYG15 yashimangiye karbideyiyongereyeho 5.19%.Mubyongeyeho, hari na raporo zijyanye no kuvura cryogenic zitezimbere imashini nkingaruka zikomeye nimbaraga zumunaniro waCarbide.Kugeza ubu, ubushakashatsi bw’intiti zo mu gihugu n’amahanga ku miterere ya karbide ya sima nyuma yo kuvura cryogenic yibanda cyane ku bintu bibiri: gukomera (harimo ubukana bwa Rockwell na Vickers gukomera) n'imbaraga zoroshye.Urwego rwo gutandukana mubikorwa rufite ingaruka nini.Igishushanyo cya 1 nicya 2 byerekana muri make impinduka zubukomezi nimbaraga zoroshye za WC-Co ciment ya karbide hamwe na Co nyuma yo kuvura cryogenic, kandi uburyo bwabo bwo guhinduka buraganirwaho.
