Impembelelo yonyango lwe-cryogenic kwiipropati zemishini ye-carbide ene-cemented

Iimpawu zoomatshini zei-carbide enesamentezibonakaliswa ikakhulu kukuqina, ukomelela okuguquguqukayo, amandla oxinzelelo, ukuqina kwempembelelo, amandla okudinwa, njl.

Ingaba unyango lwe-cryogenic lunokuphucula iimpawu zemishini ye-carbide ene-cemented iyona nto ibonakaliso ecacileyo yokusebenza kweteknoloji yonyango ye-cryogenic.U-Liu Yajun et al.kwenziwe unyango cryogenic kwi YW1iintsimbi ze-carbide.Iziphumo zibonise ukuba emva konyango lwe-cryogenic, i-microhardness yolu phawu lwecarbideiiblades zanda ukusuka kwi-1764HV ukuya kwi-2263.7HV, kwaye ubunzima be-Rockwell bonyuka ukusuka kwi-90HRA ukuya kwi-92HRA.Jiang et al.ibekwe i-YG8 ye-cemented carbide kwindawo yokushisa ephantsi ye-77K yonyango lwe-cryogenic kwaye yafumanisa ukuba ukuqina kwayo kunye namandla oxinzelelo kunyuke nge-4.9% kunye ne-10.1% ngokulandelanayo.

Chen Zhenhua et al.kwakhona wafumana iziphumo ezifanayo emva unyango cryogenic yebakala elifanayoi-carbide enesamente.I-Zhang Pingping ibeke i-YG6X i-carbide ene-cemented ecolekileyo kwibhokisi ye-cryogenic yonyango lwe-cryogenic kwaye yafumanisa ukuba amandla ayo okugoba kunye nokunyanzeliswa kwayo kwanda nge-7.6% kunye ne-10.8% ngokulandelanayo.UChen Hongwei upholiswe ngaphambiliYG15 carbide enesamentekwaye emva koko wantywiliselwa kulwelo nitrogen unyango cryogenic.Iziphumo zibonise ukuba xa kuthelekiswa nangaphambi konyango lwe-cryogenic, amandla okugobaYG15 carbide enesamenteinyuke nge-5.19%.Ukongeza, kukho neengxelo malunga nonyango lwe-cryogenic oluphucula iipropathi zoomatshini ezifana nokuqina kwempembelelo kunye namandla okudinwa.i-carbide enesamente.Okwangoku, uphando lwabaphengululi basekhaya nabangaphandle kwiipropati mechanical of carbide cemented emva unyango cryogenic ikakhulu igxile kwimiba emibini: ubulukhuni (kuquka Rockwell ubulukhuni kunye Vickers ubulukhuni) kunye namandla flexural.Iqondo lokwahluka ekusebenzeni kunempembelelo enkulu.Amanani e-1 kunye ne-2 ashwankathela utshintsho lobunzima kunye namandla aguquguqukayo e-WC-Co ene-cemented carbide kunye nomxholo we-Co emva kokunyangwa kwe-cryogenic, kunye neepatheni zabo zokutshintsha ezinokuthi zixoxwe.
