Ultrasonic characterization of defective porcelain tiles
Eren, Elif; Kurama, Semra; Janssen, R. (Soc Espanola Ceramica Vidrio, 2012)The aim of this work is the optimization of ultrasonic methods in the non-destructive testing of sintered porcelain tiles containing defects. For this reason, a silicon nitride ball, carbon black and PMMA (Polymethylmethacrylate) ... -
Wear behaviour of alpha- and alpha/beta-SiAlON ceramics stabilized with Nd2O3 and Y2O3
Kurama, Semra; Schulz, I.; Herrmann, M. (Elsevier Sci LTD, 2009)alpha- and alpha/beta-SiAlON compositions, doped with Y2O3 or Nd2O3, were densified by gas pressure sintering (GPS). The wear and mechanical properties of the materials were investigated and compared to beta-Si3N4 materials. ... -
Wear properties of alpha- and alpha/beta-SiAlON ceramics obtained by gas pressure sintering and spark plasma sintering
Kurama, Semra; Schulz, I.; Herrmann, M. (Elsevier Sci LTD, 2011)In this study, alpha- and alpha/beta-SiAlON materials, doped with Y(2)O(3) and Nd(2)O(3), were sintered using two different sintering processes: spark plasma sintering (SPS) and gas pressure sintering (GPS). The wear and ...
