Ivili lokusila idayimani lisebenzisa i-diamond abrasive njengento ekrwada, kwaye isebenzisa umgubo wesinyithi, umgubo weresin, iiseramikhi kunye nesinyithi esifakwe kwi-electroplated njengezibophelelo ngokulandelelanayo.Isixhobo se-abrasive esinesetyhula esinomngxuma osembindini sibizwa ngokuba yi-diamond grinding wheel (ivili lokusila ialloyi).

Ivili lokusila ledayimani elibotshelelwe ngeresin lihlala linobomi obuphantsi kwaye alikwazi ukuhlangabezana neemfuno zezixhobo zoomatshini bolawulo lwamanani.Ubomi obufutshane bubangelwa ikakhulu kukunganyangeki kokunxitywa kwe-resin bond ngokwayo okanye amandla aphantsi okubamba idayimani, nto leyo ebangela ukuba amasuntswana abrasive edayimani awe ngaphambi kwexesha ngexesha lokusila.Ke ngoko, indlela yokuphucula ukumelana nokunxiba kwebhondi ye-resin kunye nokuphucula amandla okubamba i-resin kwidayimani ibe sisitshixo sokuphucula ubomi benkonzo ye-resin bond diamond yokusila ivili.

Ukongezwa kwe-silicon carbide whiskers kunokuphucula kakhulu amandla, ukuqina, ukumelana nobushushu, ukupholisa, njl njl. yebhondi kunye nevili lokugaya.Amabhovu e-silicon e-carbide aneempawu ezizodwa zoomatshini kunye ne-physicochemical ezifana nobunzima obuphezulu, ukomelela okuphezulu (ukuqina), kunye nokuxhathisa okugqwesileyo kokunxiba, ke zisetyenziswa ngokubanzi kwiintsimbi, iiseramikhi, iiplastiki, njl.

Ukomeleza kunye nokuqina kwezixhobo kunye nezixhobo ezidibeneyo zokuphucula amandla ezinto ezidibeneyo kunye nokuthintela ukuncipha kunye nokuguqulwa.Imilo ye-silicon carbide whiskers ifana neenaliti, ngakumbi ukuqina kwayo kweWebster kusondele kwidayimani kwaye inokuqina okuhle kunye nokumelana nokunxiba, kwaye xa kuthelekiswa neenkozo ezirhabaxa, nokuba ububanzi bulingana nobukhulu bengqolowa yeenkozo ezirhabaxa, kukho amabhovu. ubude obuthile obudityaniswe ne-Agent inendawo enkulu yokudibanisa kunye namandla okudibanisa, okuphucula kakhulu ubomi benkonzo yevili lokugaya.

Ubungakanani be-β-ubungakanani bemicronamabhovu e-silicon carbideeziveliswe nguHongwu Nano zineempawu zokucoceka okuphezulu kunye ne-morphology elungileyo, kwaye zizinto ezikhethiweyo zokuqinisa kunye nokuqina kwezinto ezahlukeneyo ezisekelwe kwisinyithi, esekwe kwi-ceramic kunye ne-resin-based composite.Ukuqiniswa kwayo kunye nokuqina kwayo kunye nobubanzi bokusetyenziswa akuhambelani nezinye izinto.

Amabhovu e-Beta silicon carbide ziikristale ezifana nenaliti enye.Njengekristale yeathom, inoxinano oluphantsi, indawo yokunyibilika ephezulu, amandla aphezulu, imodyuli ephezulu, isantya sokwandiswa kwe-thermal ephantsi, kunye neempawu ezibalaseleyo ezifana nokumelana nokunxiba, ukumelana nokugqwala, ukumelana nobushushu obuphezulu, ukumelana ne-oxidation, njl. isiseko setsimbi, isiseko se-ceramic , Ukuqiniswa kunye nokunyanzeliswa kwezinto ezixutywe ne-resin-based composite, kuphucula kakhulu iipropati zezinto ezidibeneyo.

Izalathi zayo eziphambili zokusebenza ngokomzimba zezi zilandelayo:
