Elastic response of thermal spray deposits under indentation tests
- State Univ. of New York, Stony Brook, NY (United States)
The elastic response behavior of thermal spray deposits at Knoop indentations has been investigated using indentation techniques. The ration 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 Al{sub 2}O{sub 3}, yttria-stabilized ZrO{sub 2} (YSZ), and NiAl. Statistical tools have been used to evaluate the error estimates of the data.
