Plasma sprayed hydroxyapatite thickness

Figure 7.40 Development of all-through cracks in a plasma-sprayed hydroxyapatite coating of about 200 pm thickness, 10 0.5 pm average surface roughness (fta), 5 1% porosity and 50 9 MPa tensile adhesion strength (Heimann et at., 2001).

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...
