I-nano-alumina eqinile ye-Ceramic engu-99.99%
Ingasetshenziswa ezintweni zobumba ezisebenzayo, izinto zobumba zesakhiwo, izinto zobumba ezisobala, nemishini yendwangu.
1. Ngenxa yokuqina kwe-nano-alumina powder, ixazulula ukushiyeka kobubanzi bokusetshenziswa okulinganiselwe yi-brittleness yokushisa okuphansi. Phakathi kwazo, ama-nano-aluminium oxy-carbide (SiC) nanocomposites yiwona avelele kakhulu, futhi amandla awo okuguquguquka avela ku-single-phase alumina ceramics akhuphuke kusuka ku-300-400 MPa kuya ku-1 GPa, kanti ukuqina kokuqhekeka kwezinto kukhuphuke ngaphezu kuka-40%.
2. Ukuqina kokushisa: Ukwengezwa kwe-nano-alumina ku-substrate ye-ceramic akugcini nje ngokuthuthukisa ukusebenza kokushiswa kwe-substrate, kodwa futhi kuthuthukisa kakhulu ukuqina kokushisa kwezinto ze-substrate ye-alumina, futhi ukuqina kokushisa kuthuthukiswa izikhathi ezingu-2-3.
3. Ubuningi: Enqubweni yokubumba i-powder extrusion, i-nano-α-Al2O3 powder ingagcwaliswa ezimbotsheni ze-micron alumina powder, okunciphisa usayizi we-pore; ingcindezi yokubumba iyakhuphuka, futhi inani le-pore lingancishiswa, ngaleyo ndlela kuthuthukiswe Ubuningi be-ceramic embryos buthuthukisa ubuningi kanye nezakhiwo ze-mechanical ze-alumina ceramics ngemva kokusila.
4. Ukunciphisa izinga lokushisa lokusila: ukungezwa kwe-nano-a-Al2O3 kukhuthaza umsebenzi wokusila futhi kusiza ukunciphisa izinga lokushisa lokusila. Lapho izinga lokushisa lokusila lingu-1450 °C, amandla okugoba kanye nokuqina kokuqhekeka kufinyelela esiphezulu.
5. Ukwengezwa kwenani elincane le-nano-a-Al2O3 kungathuthukisa ngempumelelo izakhiwo zemishini zento. I-alumina ceramic ishiswa ku-1450 °C. Uma inani lokwengeza lingu-10%, amandla okuguquguquka angu-415 mPa kanti ukuqina kokuqhekeka kungu-4.1 MPa·m^1. /2.
