Abstract

Effects of high voltage screening were examined on perpendicular and parallel surface ground titania rectangular bars. A screening field at or below which 30% of titania samples break electrically was applied to each group samples. After high voltage screening, the surviving samples were subjected to mechanical strength measurement and resultant strength distribution was compared to the original distribution. After screening, the Weibull plots of perpendicular ground sample bent to become a convex curve while plots in the high strength region remained almost the same, indicating that low strength samples were selectively eliminated by the high voltage screening. On the other hand, screening effect on parallel surface ground sample was very small.
