99.99% yumbu mai tauri nano-alumina

1. Saboda superplasticity na nano-alumina foda, yana warware gazawar aikace-aikacen kewayon iyakance ta ƙarancin zafin jiki. Daga cikin su, nano-aluminum oxy-carbide (SiC) nanocomposites sune mafi mashahuri, kuma ƙarfin su na iya kasancewa daga Ƙarfin alumina na alumina guda ɗaya ya karu daga 300-400 MPa zuwa 1 GPa, kuma ƙarar taurin kayan ya karu da ƙari. fiye da 40%.

2. Thermal kwanciyar hankali: Bugu da kari na nano-alumina zuwa yumbu substrate ba kawai inganta sintering yi na substrate, amma kuma ƙwarai inganta thermal kwanciyar hankali na alumina substrate abu, da kuma thermal kwanciyar hankali da aka inganta ta 2-3 sau.

3. Density: A cikin aiwatar da foda extrusion gyare-gyare, nano-α-Al2O3 foda za a iya cika a cikin pores na micron alumina foda, wanda ya rage girman pore; an ƙara matsa lamba na gyare-gyare, kuma za a iya rage yawan adadin pores, don haka inganta yawan embryos yumbura yana inganta yawa da kayan aikin injiniya na alumina tukwane bayan sintering.

4. Rage yawan zafin jiki: ƙari na nano-a-Al2O3 yana inganta aikin motsa jiki kuma yana taimakawa wajen rage yawan zafin jiki. Lokacin da zafin zafin jiki ya kai 1450 ° C, ƙarfin sassauƙa da taurin karaya ya kai matsakaicin.

5. Bugu da ƙari na ƙananan adadin nano-a-Al2O3 zai iya inganta ingantaccen kayan aikin injiniya na kayan aiki. Alumina yumbura da aka sintered a 1450 ° C. Lokacin da ƙarin adadin shine 10%, ƙarfin sassauƙa shine 415mPa kuma taurin karaya shine 4.1 MPa·m^1. /2.
