采用压痕技术研究了热喷涂层在努氏压痕处的弹性响应行为。硬度与弹性模量之比是压痕断裂韧性评价的重要前提，通过测量努氏压痕表面尺寸的弹性恢复来确定。热喷涂层的弹性模量在可比块体材料的12%-78%的范围内，揭示了热喷涂层的各向异性行为。已经研究了各种热喷涂沉积物，包括Al 2 O3、氧化钇稳定的ZrO 2（YSZ）和NiAl。统计工具已被用来评估数据的误差估计。
The elastic response behavior of thermal spray deposits at Knoop indentations has been investigated using indentation techniques. The ratio of hardness to elastic modulus, which is an important prerequisite for the evaluation of indentation fracture toughness, is determined by measuring the elastic recovery of the in-surface dimensions of Knoop indentations. The elastic moduli of thermal spray deposits are in the range of 12%-78% of the comparable bulk materials and reveal the anisotropic behavior of thermal spray deposits. A variety of thermal spray deposits has been examined, including Al2O3, yttria-stabilized ZrO2(YSZ), and NiAl. Statistical tools have been used to evaluate the error estimates of the data.
