Acoustic Emission Measurement for Fatigue Damage Behavior of HAp Coating on Porous Titanium in Simulated Body Fluid

摘要

Though Hap coating delamination started earlier in SBF medium, the fatigue life of porous body is not affected by the solution. AE measurement could identify types of fracture during cyclic loading and its history according to the loading cycles was qualitatively determined by accumulation of plastic defamation of porous Ti components. AE measurement system is effective in detecting fracture mode of HAp coating and to discuss strength of the HAp coating layer deposited by different methods.
