1.Characters tsa CA entsoeng ka mokhoa Sol-gel

CA, e hlahisoang ke mokhoa Sol-gel, ke mofuta oa khoahlapisitseng sintered khorofo. Kahoo e boetse e mong ea bitsoang e le SG khorofo lijo-thollo. The teba kristale e nyenyane haholo, e leng 100-500nm feela, 'me ke feela ka tlaase ho moo e' ngoe lekholong tshwana corundum boholo kristale. sekotoana sa 46 # ea lijo-thollo e na le tse limilione tse likete likaroloana kristale. Ha ho sila, ho lithollo tsa ea setso ea alumina motlakase fused ba a bataletse 'me deactive,' me habonolo tla theoha ho tloha lisebelisoa khorofo tlas'a lebotho la ho sila. tšebeletso ea bophelo ba eona e khutšoanyane. Leha ho le joalo, bakeng sa CA, ke hore, SG khorofo khoahlapisitseng, kaofela apere thulaganyou e ke hape thulaganyou e lona ho intša le chorisitse. Nakong ea bophelo ba eona tšebeletso, e ncha e bohale sila bohale pepesa kamehla ha passivating khoahlapisitseng o motle kristale tla theoha ho tloha lithulusi sila tlas'a lebotho la ho sila, e leng se etsang se khoahlapisitseng kamehla ka boemo ba bohale. Joalo, le lisebelisoa khorofo entsoeng ka CA ke ya bophelo ba nako e telele le sehlopha, e ntle ho intša le chorisitse bokhoni, phahameng itšeha bokgoni, hammoho le se tukang workpieces.

Ka lebaka microstructure lona fapaneng, CA bontša phapang ka khorofo khoahlapisitseng fracture boitšoaro. CA bontša hammoho le kristale fracture senya, ha ba setso motlakase fused ea alumina bontša transgranular fracture senya. Ka lebaka leo, toughness tsa CA e habeli ho feta ea ea fused ea alumina tloaelehileng.

CA hlahisoang ke mokhoa Sol-gel o tšoanang lik'hemik'hale le thatafala ho WFA (White Fused ea alumina). Ka lebaka junifomo nyenyane microcrystalline sebopeho lona, ​​toughness phahameng le tse nyenyane robehileng tshebetso, CA ka ho pharaletseng sebediswa bakeng sa ho sila ea thepa e thata-ho-thulaganyou e joaloka sesebelisoa tšepe, thata celik, mocheso manganga motsoako tšepe, joalo-joalo

 2.Features ea lisebelisoa khorofo entsoeng ka CA

(1)  The lithollo tse bohale haholo, e leng se etsang hore e na le matla ho itšeha bokgoni, phahameng sila bokgoni. E ka sebediswa bakeng sa kgolo tebileng ho itšeha, fepa ka roughing, mosebetsi o boima le se phahameng bokgoni sila. Ho latela teko e, le 'ngoe thulaganyou e fepa ka fihla 0.3mm kapa ho feta, tšepe ho tlosa sekhahla e fetang habeli ea mabili a tloaelehile hore batho ba corundum sila.

(2) Ntle toughness, tse nyenyane abrasion, 'me mabili a sila le sebopeho tshegetsa le go tlotla molemo. Bakeng sa sebetsa ka ho nepahetseng sila le mofuta o silang, e phahameng tlhakore e nepahetse e bile boholo sebopeho tumellano ka habonolo a.

(3) High durability le bophelo bo bolelele tšebeletso. Ho ka fihla 5 to10 linako tsa mabili li neng li atile corundum sila. Tlaase Phetolo maqhubu a ka fokotsa thusang lokisa nako le Nako ea phomolo, e leng etsa hore ho esengaka hore ho sebelisa mochini tlhamiwe taolo jarolla ka ho iketsa, re hlokomela ho hlahisoeng jarolla ka ho iketsa.

(4) Good intša le chorisitse tshebetso, ha clogging. E ka tsoela tsitsitseng sila tshebetso, fokotsa khalemelo (feela ka 1/3 tsa mabili li neng li atile corundum sila) le ho ntlafatsa tlhahiso ea bokgoni.

(5) Ka tshebetso ho sila, CA sila mabili tse molemo haholo ho feta mabili tloaelehile hore batho ba corundum sila. Bakeng sa theko, CA ke ka tlaase haholo ho feta CBN le taemane abrasives, ha thatafala lona e tšoanang le eo ho tshwana fused ea alumina, e leng se etsang hore ho hlokahale equipments sila khethehileng le lisebelisoa khalemela. Gore e tle e ha e na ditlhoko khethehileng bakeng sa equipments sila 'me ha ho mathata lokisoa bapisoa CBN le taemane abrasives. E boetse e na ha ho na ditlhoko khethehileng bakeng sa ho sila mokelikeli. Kahoo, ho ke ke ho le bonolo ho jala tšebeliso ea eona.
