Ho tloha lilemong tsa bo-1980, phekolo ea cryogenic e 'nile ea sebelisoa ka katleho ho ntlafatsacarbide e entsoeng ka samente.Liphuputso tse ngata li bontšitse hore phekolo ea cryogenic e na le phello e itseng e ntle ho thepa ea mochine, ho hanyetsa ho roala, ho itšeha, ho sebetsa ha microstructure, le maemo a setseng a khatello ea carbide e entsoeng ka samente.Ka lipatlisiso tse tsoelang pele tsa bafuputsi, ho fumanoe letoto la litekanyetso tse sebetsang.le liqeto tsa bohlokoa ba saense.
(1) Phekolo ea Cryogenic e ka ntlafatsa matla a ho kobeha, ho hanyetsa le ho itšehacarbide e entsoeng ka samente, ka tsela e atlehang e lelefatsa bophelo ba tšebeletso ealisebelisoa tsa carbide tse entsoeng ka samente.Ka ho hlahloba tšusumetso ea mekhoa ea phekolo ea cryogenic ka thepa ea mochine ea carbide e entsoeng ka samente, ho lumeloa hore phello ea optimization ea phekolo ea cryogenic ha e fetohe ka tsela e lumellanang le ho fokotseha ha mocheso oa phekolo ea cryogenic le ho atolosoa ha nako ea ho tšoara.Bakeng sa limaraka tse itseng tsacarbide e entsoeng ka samente, ho na le ts'ebetso e nepahetseng ea phekolo ea cryogenic, e ka finyellang phello e ntle ka ho fetisisa ea ho ntlafatsa ka theko e tlaase.
