Iiceramics ze-Alumina zingasetyenziswa kwizixhobo ezishushu kakhulu nezigugileyo kushishino lwamandla obushushu

Kwishishini lamandla obushushu, izixhobo zihlala zonakala ngenxa yobushushu obuphezulu kunye neemeko zokuguguleka okuphezulu, nto leyo echaphazela ukuveliswa kokhuseleko kwenkqubo yonke. Ukuze kusonjululwe le ngxaki, kuyimfuneko ukufumana izixhobo ezinokumelana nobushushu obuphezulu kwaye zixhathise ukuguguleka. Izinto ze-alumina ceramic zifanelekile kakhulu.

I-Alumina ceramic luhlobo lwe-alumina (Al2O3) njengezinto eziluhlaza ezenziwe ngezinto ze-ceramic, emva kokucinezela okomileyo, emva koko zidlule kwiidigri ezingaphezu kwe-1,700 zokushisa okuphezulu. Ii-Alumina ceramics zineempawu zokuqhuba kakuhle, amandla oomatshini, ukumelana nobushushu obuphezulu kunye nokumelana nokugqwala. Ilinganiswe yiShanghai Institute of Silicate ye-Chinese Academy of Sciences, ubunzima bayo beRockwell yi-HRA80-90, ubunzima bulandela idayimani kuphela, bungaphezulu kakhulu kunokumelana nokugqwala kwentsimbi engagugiyo kunye nentsimbi engagqwaliyo. Ukumelana nokugqwala kuphindwe ka-266 kunentsimbi ye-manganese kunye namaxesha ali-171.5 kunentsimbi ephezulu ye-chromium. Ngokwesi sifundo sethu sokulandelela abathengi iminyaka engaphezu kweshumi, phantsi kweemeko ezifanayo zokusebenza, ubomi benkonzo yezixhobo bunokwandiswa ubuncinane amaxesha alishumi.

Iiseramikhi zeAlumina zingasetyenziswa kwiindawo zezixhobo ezishushu kakhulu nezigugileyo kwishishini lamandla obushushu, ezifana neefeni, iirotha zepompo, iigobolondo, iipayipi, izihlalo, iiringi zokuvala, njl. Ezi ndawo kufuneka zimelane nobushushu obuphezulu, uxinzelelo oluphezulu kunye nemidiya erhabaxa, ngoko ke kufuneka zisebenzise izixhobo ezikwaziyo ukumelana nokugugileka ukuze zenze.

Kwishishini lamandla obushushu, umsila wamalahle sesona sixhobo siphambili, kwaye ukusetyenziswa kwawoiiseramikhi ezingagugiyoinokuphucula ngokufanelekileyo ubomi benkonzo yomatshini wokugaya amalahle, ize iqinisekise ukusebenza kwenkqubo yonke yebhoyila. Oku akunakunciphisa kuphela ixesha lokungasebenzi kwezixhobo, kuqinisekise ukusebenza okuzinzileyo kwenkqubo yebhoyila, kodwa kunciphise neendleko zokugcinwa kwezixhobo, okuhambelana nokufuna iingenelo zoqoqosho kushishino lwamandla obushushu.

Kufuneka kuqatshelwe ukuba kwiindlela ezisebenzayo, iinkcukacha, umxholo, ukucubungula kunye nokusetyenziswa kweeseramikhi ezingagugiyo kufuneka zikhethwe ngokweemeko zokusebenza zokwenyani ukuqinisekisa ukusebenza kunye neziphumo ezilungileyo.
