Li-abrasives li ka aroloa ka mekhahlelo e 'meli: li-abrasives tse tloaelehileng (tse kang aluminium oxide, silicon carbide, joalo-joalo) le li-abrasives tse matla haholo (taemane, cubic boron nitride, joalo-joalo).
CBN le Jinzeshi li thata ebile ha li na matla ho feta li-abrasives tse tloaelehileng, empa li theko e boima haholo.Ka nako e ts'oanang, li-abrasives tse matla haholo ke li-conductivity tse ntle tsa mocheso (mocheso oa mocheso oa daemane ke makhetlo a 6 a koporo), ha li-abrasives tse tloaelehileng ke lisebelisoa tsa ceramic, kahoo li na le adiabatic.
Superhard abrasive e boetse e na le diffusivity e phahameng ea mocheso, ke hore, e na le bokhoni ba ho qhala mocheso ka potlako.Tšobotsi ena e etsa hore superhard abrasive e be le sebopeho sa "seha se batang".The abrasion resistance of superhard abrasives e boetse e molemo haholo ho feta ea abrasives tloaelehileng, empa litšobotsi tsena tsa superhard abrasives ha li bolele hore li loketse bohle.mekhoa ea ho sila.
E 'ngoe le e' ngoe ea abrasive e na le sebaka sa eona sa kopo se nepahetseng ka ho fetisisa, kahoo ke habohlokoa ho utloisisa litšobotsi tsa abrasive ka 'ngoe.Mohlala, li-abrasives tsa alumina ceramic - tseo ka linako tse ling li bitsoang li-abrasives tsa seed gel (SG) kapa li-abrasives tsa ceramic - hangata li na le khanyetso e ntle ea ho apara le ho boloka sebopeho ho feta alumina e qhibilihisitsoeng (e tloaelehileng).Leha ho le joalo, li-abrasive tsa ceramic le tsona li na le masimo a ts'ebeliso a nepahetseng ka ho fetesisa.
Alumina: Al2O3 ke abrasive e theko e tlaase ka ho fetisisa.Ha u sila tšepe e thata, ts'ebetso e ntle haholo.Tlas'a boemo ba ho apara ka mokhoa o tsoelang pele, li-superalloys tsa nickel base li ka boela tsa thehoa.Al2O3 e na le ho ikamahanya le maemo ho mefuta e fapanengho silamaemo, joalo ka lisebelisoa tse bonolo le tse thata, ho itšeha habonolo le ho itšeha ho boima, 'me li ka sila sephetho se phahameng haholo.
Ceramic alumina: alumina ea ceramic e na le matla a phahameng, kahoo e loketse ka ho fetisisa bakeng sa liketsahalo tseo ho tsona moroalo oa matla a ho itšeha oa thollo e 'ngoe le e' ngoe ea abrasive e leng holimo.Ceramic alumina e sebetsa haholo ho sila ka cylindrical le sefofane se seholo se khutlisetsang ho sila ka tšepe e thata.Empa ha e tšoanelehe bakeng sa li-arc tse telele tsa ho itšeha le matla a manyane a thollo e le 'ngoe ea abrasive, joalo ka ho sila ka hare ho selikalikoe, ho sila lijo tsa creep, joalo-joalo Leha ho le joalo, likaroloana tsa ceramic alumina abrasive tse fetotsoeng ka "ho otlolla" li ka boela tsa sebelisoa ho sebetsana le viscous.ts'epe e sa beng le mabali, superalloy, joalo-joalo esita le ha arc ea ho itšeha e le telele.Ka nako ena, karo-karolelano ea sebopeho (karolelano ea bolelele ba bophara) ea likaroloana tsa abrasive e fihla ho 5.
