I-99.99% ye-ceramic topped nano-alumina
Ingasetyenziselwa iiseramikhi ezisebenzayo, iiseramikhi zesakhiwo, iiseramikhi ezibonakalayo, oomatshini belaphu.
1. Ngenxa yokuba i-nano-alumina powder inamandla kakhulu, isombulula iingxaki zoluhlu lwesicelo olunqunyelwe kukungabi namandla obushushu obuphantsi. Phakathi kwazo, ii-nano-aluminium oxy-carbide (SiC) nanocomposites zezona zibalaseleyo, kwaye amandla azo okuguquguquka avela kwi-single-phase alumina ceramics anyuke ukusuka kwi-300-400 MPa ukuya kwi-1 GPa, kwaye ukuqina kokuqhekeka kwezinto kunyuke ngaphezulu kwe-40%.
2. Uzinzo lobushushu: Ukongezwa kwe-nano-alumina kwi-substrate yeseramikhi akuphuculi nje kuphela ukusebenza kwe-sintering ye-substrate, kodwa kukwaphucula kakhulu uzinzo lobushushu bezinto ze-substrate ye-alumina, kwaye uzinzo lobushushu luphuculwa amaxesha ama-2-3.
3. Uxinano: Kwinkqubo yokubumba i-powder extrusion, i-nano-α-Al2O3 powder ingazaliswa kwii-pores ze-micron alumina powder, nto leyo enciphisa ubungakanani be-pore; uxinzelelo lokubumba luyanda, kwaye inani lee-pores lingancitshiswa, ngaloo ndlela kuphuculwe Uxinano lwee-ceramic embryos luphucula uxinano kunye neempawu zoomatshini ze-alumina ceramics emva kokusila.
4. Ukunciphisa ubushushu bokutshiza: ukongezwa kwe-nano-a-Al2O3 kukhuthaza umsebenzi wokutshiza kwaye kunceda ukunciphisa ubushushu bokutshiza. Xa ubushushu bokutshiza buyi-1450 °C, amandla okugoba kunye nokuqina kokuqhekeka kufikelela kwinqanaba eliphezulu.
5. Ukongezwa kwenani elincinci le-nano-a-Al2O3 kunokuphucula ngempumelelo iipropati zoomatshini zezinto. I-alumina ceramic itshiswa kwi-1450 °C. Xa ubungakanani bokongeza buyi-10%, amandla e-flexural yi-415 mPa kwaye ukuqina kokuqhekeka yi-4.1 MPa·m^1. /2.
