The surface defects on the samples, which are based on alumina, exposed to thermal shocks and cavitations erosion were analyzed using image analysis. For both types of experimental testing, the samples are made of the same shape and size. The specimens contain different amounts of alumina fibers (samples without fiber and with of 1 and 2 wt.% of the fibers). The surface defects were characterized by their morphological parameters determined using image analysis procedure. Sixteen parameters are used for the image analysis. The results show that the damage caused by thermal shocks and cavitations were different and the greatest difference was in roundness and fractal dimension.
