CHAPTER 4 VOLCANIC ASH AND ITS PENETRATION MECHNISMS IN TBCS mechanisms are involved in degradation of TBC by volcanic ash. The first mechanism is physical penetration: molten volcanic ash penetrates into TBC columnar gaps and pores, which combines and stiffens the top coat by sintering. Second, molten volcanic ash also attack YSZ top coat through chemical reactions: it depletes the yttria, which may lead to the harmful phase transformation of YSZ [40]. Further experiments would be discussed in next section.
