Thatha nawe nge tungsten carbide porosity

I-Tungsten carbide yimathiriyeli eshinyeneyo neqinileyo esetyenziswa rhoqo kwiintlobo ngeentlobo zezicelo zemizi-mveliso ngenxa yeempawu zayo ezikhethekileyo ezinje ngamandla, ukumelana nokunxiba, kunye nokuqina.Nangona kunjalo, njengayo nayiphi na into, ayithinteli ngokupheleleyo ukungafezeki, kwaye i-porosity yenye yezinto eziqhelekileyo ezinxulumene nazo.tungsten carbide.

Porosity kwitungsten carbideibhekisa kubukho be-voids, iintanda, okanye izithuba ngaphakathi kwesixhobo esinokusenza buthathaka ulwakhiwo kunye nokusebenza kwayo ngokubanzi.Ezi pores zingabangelwa yizinto ezahlukeneyo, kubandakanywa iindlela zokuvelisa ezingafanelekanga, ukungahambisani kwezinto ezisetyenzisiweyo, kunye nokuhluka kwenkqubo ye-sintering.

I-Porosity kwi-tungsten carbide ingaba nefuthe elibalulekileyo kwiipropati kunye nokusebenza kwezinto eziphathekayo.I-porosity ephezulu inokunciphisa amandla ezinto eziphathekayo, ukuqina, kunye nokuqina, okwenza kube lula ukuqhekeka kunye nokunxiba.Ukongeza, i-porosity inokuchaphazela amandla ezinto zokuqhuba ukushisa, okunokukhokelela kwimiba efana nokuqhekeka kwe-thermal kunye nokuguqulwa.

Ukunciphisa i-porosity kwi-tungsten carbide, abavelisi banokusebenzisa ubuchule obukhethekileyo obufana noxinzelelo olushushu lwe-isostatic, olunokunceda ukuvala naziphi na iipores kwizinto eziphathekayo.Uxinzelelo olushushu lwe-isostatic lubandakanya ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu kwizinto ze-tungsten carbide, ezinceda ukuphelisa naziphi na izikhewu, i-voids, okanye iintanda kwizinto eziphathekayo.Kuko konke,

I-porosity ngumba oqhelekileyo ohambelana ne-tungsten carbide, kodwa inokuncitshiswa ngokusebenzisa iindlela ezifanelekileyo zokuvelisa kunye nobuchule, kunye nokukhetha izinto ezisemgangathweni ophezulu.
