Stress Analysis by the Hole-Drilling Strain Gauge Method

63 Stress Analysis by the Hole-Drilling Strain Gauge Method 

The effect of residual stress on the dissolution of hydroxyapatite coatings was investigated on plasma-sprayed coatings of 80, 110 and 200 pm thickness (Han, Xu and Lu, 2001). Residual stresses in the coatings were measured with a holedrilling method. Dissolution of the coatings was monitored along with an examination of the phase composition. The results showed that both tensile residual
