Umphumela wokwelashwa kwe-cryogenic kuzakhiwo zemishini ye-carbide enosimende

Izici zemishini yei-carbide enosimendezibonakala kakhulu ngobulukhuni, amandla okugobeka, amandla okucindezela, ukuqina komthelela, amandla okukhathala, njll.

Kungakhathaliseki ukuthi ukwelashwa kwe-cryogenic kungathuthukisa izakhiwo zemishini ye-cemented carbide iyinkulumo enembile kakhulu yokusebenza kobuchwepheshe bokwelashwa kwe-cryogenic.U-Liu Yajun et al.wenze ukwelashwa kwe-cryogenic ku-YW1ama-carbide blades.Imiphumela yabonisa ukuthi ngemva kokwelashwa cryogenic, microhardness yalesi brandi-carbideama-blades anda esuka ku-1764HV aya ku-2263.7HV, futhi ukuqina kwe-Rockwell kukhuphuke kusuka ku-90HRA kuya ku-92HRA.Jiang et al.ibeke i-YG8 i-carbide enosimende endaweni yokushisa ephansi engu-77K yokwelashwa kwe-cryogenic futhi yathola ukuthi ubulukhuni bayo namandla okucindezela akhuphuke ngo-4.9% no-10.1% ngokulandelana.

U-Chen Zhenhua et al.futhi wathola imiphumela efanayo ngemva ukwelashwa cryogenic of the grade ofi-carbide enosimende.U-Zhang Pingping ubeke i-YG6X i-carbide enosimende ecolekile ebhokisini le-cryogenic lokwelashwa kwe-cryogenic futhi wathola ukuthi amandla ayo okugoba namandla okuphoqa anyuke ngo-7.6% no-10.8% ngokulandelana.U-Chen Hongwei upholiswe ngaphambiliI-YG15 i-carbide enosimendebese uyicwilisa ku-nitrogen ewuketshezi ukuze ulashwe i-cryogenic.Imiphumela yabonisa ukuthi uma kuqhathaniswa ngaphambi kokwelashwa kwe-cryogenic, amandla okugoba weI-YG15 i-carbide enosimendezishintshiwe zaba ngu-+5.19% ngesonto.Ngaphezu kwalokho, kukhona nemibiko mayelana nokwelashwa kwe-cryogenic ukuthuthukisa izakhiwo zemishini ezifana nokuqina komthelela kanye namandla okukhathalai-carbide enosimende.Njengamanje, ucwaningo lwezazi zasekhaya nezakwamanye amazwe mayelana nezakhiwo zemishini ye-carbide enosimende ngemva kokwelashwa kwe-cryogenic ngokuyinhloko lugxile ezicini ezimbili: ubulukhuni (kuhlanganise nobulukhuni be-Rockwell kanye nobulukhuni be-Vickers) namandla okuguquguquka.Izinga lokwehluka ekusebenzeni linomthelela omkhulu.Amanani 1 kanye ne-2 afingqa izinguquko zokuqina namandla okuguquguquka kwe-WC-Co ehlanganiswe ne-carbide enokuqukethwe kwe-Co ngemva kokwelashwa kwe-cryogenic, futhi amaphethini abo okushintsha okungenzeka axoxwe.
