摘 要：La2 Zr2 O7 (LZ) is a promising thermal barrier coating material for the high temperature applications. The fracture toughness and microhardness of nanocrystalline LZ (n-LZ), microcrystalline LZ (m-LZ) and LZ-5mol%8YSZ (LZ-5-8YSZ) composite (8YSZ for zirconia stabilized by 8 mol% ytrria) were studied. The n-LZ had a thermal expansion coeffinanofication was an efficient way to increase the toughness and thermal expansion coefficient of LZ. The composite LZ-5-superhigh pressure (SHP).
