Ka hopena o ka lapaʻau cryogenic i nā waiwai mechanical o ka carbide cemented

ʻO nā mea mechanical ocarbide simaʻike nui ʻia i ka paʻakikī, ka ikaika flexural, ka ikaika compressive, ka paʻakikī hopena, ka ikaika luhi, etc.

Hiki paha i ka lapaʻau cryogenic ke hoʻomaikaʻi i nā waiwai mechanical o ka carbide cemented ka hōʻike intuitive loa o ka pono o ka ʻenehana lapaʻau cryogenic.Liu Yajun et al.ua hoʻokō i ka mālama cryogenic ma YW1nā lau karbida.Ua hōʻike ʻia nā hopena ma hope o ka mālama ʻana i ka cryogenic, ka microhardness o kēia brandcarbideUa hoʻonui ʻia nā lau mai 1764HV a i 2263.7HV, a ua hoʻonui ʻia ka paʻakikī Rockwell mai 90HRA a i 92HRA.ʻO Jiang et al.kau i ka YG8 cemented carbide ma kahi haʻahaʻa haʻahaʻa haʻahaʻa o 77K no ka cryogenic lapaʻau a ʻike ʻia ua hoʻonui ʻia kona paʻakikī a me ka ikaika compressive e 4.9% a me 10.1%.

ʻO Chen Zhenhua et al.loaʻa pū i nā hopena like ma hope o ka mālama ʻana i ka cryogenic o ka papa like ocarbide sima.Ua hoʻokomo ʻo Zhang Pingping i ka carbide cemented YG6X i loko o kahi pahu cryogenic no ka mālama ʻana i ka cryogenic a ua ʻike ʻo ia ua hoʻonui ʻia kona ikaika kulou a me ka ikaika hoʻoikaika e 7.6% a me 10.8%.Ua hoʻoluʻu mua ʻo Chen HongweiYG15 carbide simaa laila hoʻokomo ʻia i loko o ka wai hau no ka mālama cryogenic.Ua hōʻike ʻia nā hopena i hoʻohālikelike ʻia me ka mālama ʻana i ka cryogenic, ka ikaika kulou oYG15 carbide simaua hoʻonui ʻia e 5.19%.Eia kekahi, aia kekahi mau moʻolelo e pili ana i ka mālama ʻana i ka cryogenic e hoʻomaikaʻi ana i nā waiwai mechanical e like me ka paʻakikī o ka hopena a me ka ikaika luhi.carbide sima.I kēia manawa, ʻo ka noiʻi ʻana o nā ʻimi noiʻi kūloko a me nā ʻāina ʻē e pili ana i nā waiwai mechanical o ka carbide cemented ma hope o ka mālama ʻana i ka cryogenic ka mea nui i ʻelua ʻaoʻao: ʻo ka paʻakikī (me ka paʻakikī ʻo Rockwell a me ka paʻakikī Vickers) a me ka ikaika flexural.He hopena nui ka degere o ka hoʻololi ʻana i ka hana.Hōʻuluʻulu nā kiʻi 1 a me 2 i nā loli o ka paʻakikī a me ka ikaika flexural o WC-Co cemented carbide me Co content ma hope o ka mālama ʻana i ka cryogenic, a ua kūkākūkā ʻia ko lākou mau ʻano hoʻololi.
