I-99.99% I-Ceramic ilukhuni i-nano-alumina
Ingasetyenziselwa iiseramics ezisebenzayo, iiseramics zesakhiwo, iiseramics ezicacileyo, oomatshini bempahla.
1. Ngenxa ye-superplasticity ye-nano-alumina powder, isombulula iintsilelo zoluhlu lwesicelo olulinganiselwe yi-brittleness ephantsi yobushushu. Phakathi kwazo, i-nano-aluminium oxy-carbide (i-SiC) i-nanocomposites iyona nto ibalaseleyo, kwaye amandla abo aguquguqukayo avela kwi-single-phase-alumina ceramics yanda ukusuka kwi-300-400 MPa ukuya kwi-1 GPa, kunye nokuqina kokuphuka kwezinto kwanda ngakumbi. ngaphezu kwama-40%.
2. Ukuzinza kwe-thermal: Ukongezwa kwe-nano-alumina kwi-substrate ye-ceramic akugcini nje ukuphucula ukusebenza kwe-sintering ye-substrate, kodwa kuphucula kakhulu ukuzinza kwe-thermal ye-alumina substrate material, kunye nokuzinza kwe-thermal kuphuculwe ngamaxesha angama-2-3.
3. Ubuninzi: Kwinkqubo yokubumba i-powder extrusion, i-nano-α-Al2O3 powder ingazaliswa kwiipores ze-micron alumina powder, eyanciphisa ubukhulu bepore; uxinzelelo lokubumba luyanda, kwaye inani leepores lingancitshiswa, ngaloo ndlela liphucula Ubuninzi bee-embryo ze-ceramic buphucula ukuxinana kunye neempawu zomatshini ze-alumina ceramics emva kokucoca.
4. Ukunciphisa ukushisa kwe-sintering: ukongezwa kwe-nano-a-Al2O3 kukhuthaza umsebenzi we-sintering kwaye kunceda ukunciphisa ukushisa kwe-sintering. Xa iqondo lobushushu le-sintering liyi-1450 °C, amandla okuguquguquka kunye nokuqina kokwaphuka kufikelela kwelona qondo liphezulu.
5. Ukongezwa kwenani elincinci le-nano-a-Al2O3 kunokuphucula ngokufanelekileyo iimpawu zemishini yezinto. I-alumina ceramic ifakwe kwi-1450 °C. Xa isixa esongezelelweyo siyi-10%, amandla e-flexural yi-415 mPa kunye nokuqina kwe-fracture yi-4.1 MPa · m^1. /2.
