TY - JOUR ID - 72067 TI - Multi-step Electrophoretic Deposition of α-Al2O3 Nanoparticles on Carbon Substrate (TECHNICAL NOTE) JO - International Journal of Engineering JA - IJE LA - en SN - 1025-2495 AU - sadeghi, ali asghar AD - Ceramic department, Material and Energy Research C, Materials and Energy Research Center, Tehran, Iran Y1 - 2013 PY - 2013 VL - 26 IS - 1 SP - 19 EP - 24 KW - Electrophoretic deposition KW - Carbon KW - coating KW - Al2O3 nanoparticle DO - N2 - in the present study, electrophoretic deposition (EPD) was used to obtain dense and crack-free layers of Al2O3 on carbon substrate. Microstructural study of the obtained layers by scanning electron (SEM) and optical microscopy (OM) approved that crack-free layers can be obtained by EPD technique. According to obtained results, isopropanol is a suitable media to obtian compact layers which is attributed to unique properties of this media. The crack- free layers were obtained using multi-step electrophretic depostion while using continous EPD process led to the deposition of severly cracked layers. It seems that cracking behaviour of electrophoretically deposited films depends on drying conditions.
