99.99% Ceramic toughened nano-alumina
Ingasetshenziselwa izitsha zobumba ezisebenzayo, i-ceramics yesakhiwo, izitsha zobumba ezisobala, imishini yendwangu.
1. Ngenxa ye-superplasticity ye-nano-alumina powder, ixazulula ukushiyeka kwebanga lesicelo elikhawulelwe ukuqina okuphansi kwezinga lokushisa. Phakathi kwazo, ama-nano-aluminium oxy-carbide (SiC) ama-nanocomposites agqama kakhulu, futhi amandla awo aguquguqukayo avela ku-alumina ceramics yesigaba esisodwa senyuke ukusuka ku-300-400 MPa kuya ku-1 GPa, futhi ukuqina kokuphuka kwento kukhuphuke ngokungaphezulu. ngaphezu kwama-40%.
2. Ukuzinza kwe-thermal: Ukwengezwa kwe-nano-alumina ku-substrate ye-ceramic akugcini nje ukuthuthukisa ukusebenza kwe-sintering ye-substrate, kodwa futhi kuthuthukisa kakhulu ukuzinza okushisayo kwe-alumina substrate impahla, futhi ukuzinza okushisayo kuthuthukiswa izikhathi ezingu-2-3.
3. Ubuningi: Esikhathini sokubumba kwe-powder extrusion, i-nano-α-Al2O3 powder ingagcwaliswa kuma-pores we-micron alumina powder, okunciphisa usayizi we-pore; ingcindezi yokubumba iyanda, futhi inani lama-pores lingancishiswa, ngaleyo ndlela lithuthuke Ubuningi bemibungu ye-ceramic buthuthukisa ukuminyana kanye nezakhiwo zemishini ye-alumina ceramics ngemva kokucwiliswa.
4. Ukunciphisa izinga lokushisa le-sintering: ukungezwa kwe-nano-a-Al2O3 kukhuthaza umsebenzi we-sintering futhi kusiza ukunciphisa izinga lokushisa le-sintering. Uma izinga lokushisa le-sintering lingu-1450 °C, amandla okuguquguquka nokuqina kokuphuka kufinyelela phezulu.
5. Ukwengezwa kwenani elincane le-nano-a-Al2O3 kungathuthukisa ngokuphumelelayo izakhiwo zemishini yezinto ezibonakalayo. I-alumina ceramic ifakwe ku-1450 ° C. Uma inani elingeziwe lingu-10%, amandla e-flexural angu-415 mPa futhi ukuqina kokuphuka kungu-4.1 MPa·m^1. /2.
