Phello ea phekolo ea cryogenic ho thepa ea mochine ea carbide e entsoeng ka samente

Thepa ea mechine eacarbide e entsoeng ka samenteli bonahala haholo ka ho thatafala, matla a ho feto-fetoha ha maemo, matla a hatellang, ho ba le tšusumetso e matla, matla a mokhathala, joalo-joalo.

Ho sa tsotellehe hore na phekolo ea cryogenic e ka ntlafatsa thepa ea mechine ea carbide e entsoeng ka samente ke pontšo e hlakileng ka ho fetisisa ea katleho ea theknoloji ea phekolo ea cryogenic.Liu Yajun et al.e entse kalafo ea cryogenic ho YW1likhaba tsa carbide.Liphello li bontšitse hore ka mor'a phekolo ea cryogenic, microhardness ea mofuta ona oacarbideli-blades li eketsehile ho tloha ho 1764HV ho ea ho 2263.7HV, 'me boima ba Rockwell bo ile ba eketseha ho tloha ho 90HRA ho ea ho 92HRA.Jiang et al.behile YG8 samente carbide tikolohong e tlaase mocheso oa 77K bakeng sa kalafo cryogenic le ho fumana hore ho thatafala ha eona le matla compressive e eketsehile ka 4,9% le 10.1% ka ho latellana.

Chen Zhenhua et al.hape o ile a fumana liphello tse tšoanang ka mor'a kalafo cryogenic tsa sehlopha se tšoanang sacarbide e entsoeng ka samente.Zhang Pingping o behile YG6X e entsoeng hantle e entsoeng ka samente carbide ka lebokoseng la cryogenic bakeng sa phekolo ea cryogenic 'me a fumana hore matla a eona a ho koba le matla a ho qobella a eketsehile ka 7.6% le 10.8% ka ho latellana.Chen Hongwei e pholile peleYG15 carbide e entsoeng ka samenteebe e qoelisoa ka har'a naetrojene e metsi bakeng sa kalafo ea cryogenic.Liphetho li bontšitse hore ha li bapisoa le pele ho kalafo ea cryogenic, matla a kobehang aYG15 carbide e entsoeng ka samentee eketsehile ka 5.19%.Ho phaella moo, ho boetse ho na le litlaleho tsa phekolo ea cryogenic e ntlafatsang thepa ea mochine e kang ho ba le tšusumetso e matla le matla a mokhathala.carbide e entsoeng ka samente.Hona joale, lipatlisiso tsa litsebi tsa malapeng le tsa linaheng tse ling mabapi le thepa ea mechine ea carbide e entsoeng ka samente ka mor'a phekolo ea cryogenic haholo-holo e lebisa tlhokomelo likarolong tse peli: ho thatafala (ho akarelletsa le Rockwell hardness le Vickers hardness) le matla a flexural.Tekanyo ea ho fapana ha ts'ebetso e na le tšusumetso e kholo.Lipalo tsa 1 le 2 li akaretsa liphetoho tse thata le matla a flexural a WC-Co cemented carbide le Co content ka mor'a phekolo ea cryogenic, 'me mekhoa ea bona ea phetoho e ka' nang ea tšohloa e tšohloa.
