Ngokuvamile lapho ubulukhuni bezinto ezibonakalayo buphakeme, ukumelana nokugqoka nakho kuphezulu;amandla aphezulu e-flexural, ukuqina komthelela nakho kuphezulu.Kodwa ukuphakama kokuqina kwempahla, amandla ayo okugoba kanye nokuqina komthelela kuphansi.Insimbi enesivinini esikhulu ngenxa yamandla okugoba aphezulu kanye nokuqina komthelela, kanye nokusebenza kahle komshini, kuseyizinto zamathuluzi ezisetshenziswa kakhulu, kulandelwa i-carbide.
I-polycrystalline cubic boron nitride ifaneleka ukusika insimbi eqinile eqinile nensimbi eqinile, njll.;Idayimane ye-Polycrystalline ifaneleka ukusika izinsimbi ezingezona ayoni, nama-alloys, amapulasitiki nensimbi yengilazi, njll.;Insimbi yensimbi yensimbi ye-Carbon ne-alloy tool manje isisetshenziswa kuphela njengamafayela, amazinyo epuleti nompompi namanye amathuluzi.
Okufakwayo okunenkomba ye-Carbide manje sekunamathelwe nge-titanium carbide, i-titanium nitride, ungqimba oluqinile lwe-aluminium oxide noma ungqimba oluqinile oluhlanganisiwe ngokufaka umhwamuko wamakhemikhali.Ukufakwa komhwamuko ongokoqobo akwenzelwanga nje kuphela amathuluzi e-carbide kodwa namathuluzi e-HSS afana nokubhoboza, izinti, ompompi nezinsimbi zokugaya.Ukufakwa okuqinile kusebenza njengesithiyo ekusakazweni kwamakhemikhali nokudluliswa kokushisa, kwehlisa ijubane ukuguga kwethuluzi ngesikhathi sokusika, futhi kwandise ukuphila kokufakwa okuboshiwe cishe izikhathi ezingu-1 kuya kwezingu-3 noma ngaphezulu uma kuqhathaniswa nezingamboziwe.
Ngenxa yokushisa okuphezulu, ukucindezela okukhulu, isivinini esikhulu, kanye nasezingxenyeni zokusebenza zemidiya ezibolayo, ukusetshenziswa kwezinto ezinzima emshinini kuya ngokuya ngokuya phezulu, izinga lokuzenzakalela kokusika nokunyathelisa kanye nezidingo zokunemba komshini liya ngokuya liphakeme.Ukuze uvumelane nalesi simo, isiqondiso sokuthuthukiswa kwamathuluzi kuzoba ukuthuthukiswa kanye nokusetshenziswa kwezinto ezintsha zamathuluzi;ukuthuthukiswa okuqhubekayo kobuchwepheshe bokumboza bezinto zokubeka umhwamuko wethuluzi, ekuqineni okuphezulu namandla aphezulu e-substrate efakwe embotsheni yokuqina okuphezulu, isisombululo esingcono sokungqubuzana phakathi kokuqina kwento yethuluzi namandla ethuluzi;ukuthuthukiswa okuqhubekayo kwesakhiwo sethuluzi lokukhomba;ukuthuthukisa ukunemba kokukhiqiza kwethuluzi lokunciphisa umehluko wekhwalithi yomkhiqizo wensimbi ephezulu ye-manganese kuyinto enzima-kuya-umshini.Izimfuneko eziphakeme zezinto zamathuluzi.
　　

Ngokuvamile, izidingo ithuluzi impahla ubulukhuni obomvu, okuhle bafake ukumelana, amandla aphezulu, ukuqina kanye conductivity ezishisayo.Ukusika insimbi ephezulu ye-manganese kungakhetha i-carbide, i-cermet ukwenza ithuluzi lokusika impahla.Okwamanje, isicelo esivame kakhulu kuseyi-carbide enosimende, lapho uhlobo lwe-YG lwe-carbide enosimende lunamandla aphezulu aguquguqukayo kanye nokuqina komthelela (uma kuqhathaniswa nohlobo lwe-YT lwe-carbide enosimende), olunganciphisa umphetho wokusika lapho usikwa.Ngesikhathi esifanayo, i-YG carbide ine-conductivity engcono yokushisa, evumela ukuchithwa kokusika ukushisa okuvela esihlokweni sethuluzi, ukunciphisa izinga lokushisa kwephuzu lethuluzi nokugwema ichopho lethuluzi ekushiseni ngokweqile nasekuthambeni. ukucutshungulwa kokugaya kwe-YG carbide kungcono, futhi kungalola ukukhiqiza unqenqema olucijile.
Ngokuvamile, ukuqina kwethuluzi kuncike ebulukhunini obubomvu, ukumelana nokugqoka kanye nokuqina komthelela wezinto zamathuluzi.Uma uhlobo lwe-YG lwe-carbide enosimende luqukethe i-cobalt eyengeziwe, amandla okugoba kanye nokuqina komthelela kuhle, ikakhulukazi amandla okukhathala ayathuthukiswa, ngakho-ke ilungele ukugoqa ngaphansi kwesimo somthelela nokudlidliza;uma iqukethe i-cobalt encane, ubulukhuni bayo, ukumelana nokugqoka kanye nokumelana nokushisa kuphakeme, kulungele ukuqedwa kokusika okuqhubekayo.
