Ziziphi iingenelo kunye nokungalunganga kwe-silicon carbide xa kuthelekiswa ne-silicon nitride, i-aluminium oxide kunye ne-zirconia?

Eyona ntsilelo inkulu yei-silicon carbidekukuba kunzima sinter!
I-Silicon nitride ibiza kakhulu!

Ukuguqulwa kwesigaba kunye nokuqina kwe-zirconia akuzinzile kwaye ngamanye amaxesha kusebenza. Nje ukuba le ngxaki yoyisiwe, hayi i-zirconia kuphela, yonke intsimi ye-ceramic inokuba nempumelelo! .

Ialumina ixhaphake kakhulu kwaye inexabiso eliphantsi, kwaye inokumelana nobushushu obulungileyo.
I-Zirconia inokumelana nokunxiba okungcono kune-alumina kunye nobushushu obuphezulu, kodwa ukuxhathisa ukothuka kwe-thermal kubi kune-alumina.
I-Silicon nitride ineempawu ezintle ezibanzi ezifana nokunganyangeki kunye nokuxhathisa ukothuka kwe-thermal, kodwa ubushushu bokusebenzisa bungaphantsi kunezinye ezimbini. Eyona ibiza kakhulu.
Iiseramics ze-alumina zezona zixhobo zokuqala ezenziwe nge-ceramic. Ixabiso eliphantsi, ukusebenza okuzinzileyo kunye neemveliso ezahlukeneyo. Imakethi ngokuqinisekileyo yeyona aluminium inkulu kwaye inkulu, ngoba? Thelekisa ezimbini zokugqibela kwaye uya kuqonda.

Ikakhulu ithelekiswa ngokubhekiselele ekusebenzeni kunye nexabiso. Emva koko indleko-esebenzayo kwimbono yemarike.
Ngokwexabiso, i-alumina yeyona inexabiso eliphantsi, kwaye inkqubo yokulungiswa kwemathiriyeli engumgubo nayo ikhule kakhulu. Ezi zimbini zokugqibela zineengxaki ezicacileyo kulo mba, okuyenye yeengxaki ezithintela ukuphuhliswa kwezi zimbini zokugqibela.
Ngokubhekiselele ekusebenzeni, iimpawu zomatshini ezifana namandla kunye nokuqina kwe-silicon nitride kunye ne-zirconia zingcono kakhulu kunezo ze-alumina. Kubonakala ngathi ukusebenza kweendleko kufanelekile, kodwa ngokwenene kukho iingxaki ezininzi.
Ukususela kumbono we-zirconia, inobunzima obuphezulu ngenxa yobukho bezinzile, kodwa ubunzima bayo obuphezulu bunobunzima bexesha. Ngokomzekelo, emva kokuba isixhobo se-zirconia sishiywe emoyeni ixesha elithile, siya kulahlekelwa ukuzinza kunye nokusebenza kuya kwehla kakhulu okanye ukuqhekeka! !! !! Ngaphezu koko, akukho nqanaba le-metastable kwiqondo lokushisa eliphezulu, ngoko akukho bunzima obuphezulu. Ngoko ke, ukusetyenziswa kweqondo lokushisa eliphezulu kunye nokushisa kwegumbi kunokuthintela kakhulu ukuphuhliswa kwe-zirconia. Kufuneka kuthiwe yeyona incinci kwiimarike ezintathu.
Ukuthetha nge-silicon nitride, ikwayi-ceramic ethandwayo kwiminyaka engamashumi amabini edlulileyo, kodwa inkqubo yokulungiswa kwemveliso egqityiweyo inzima kakhulu kune-alumina, engcono kakhulu kune-zirconia, kodwa ayikalunga njenge-alumina.
