                        5 based glass during its sintering process. Double layered coatings were obtained by Plasma Spraying and composed of 50 μm commercial HA, followed by a 50 μm (HA)/P
                        2O
                        5-CaO based glass composite coating. Samples were characterized by X-ray diffraction (XRD) analysis and it was shown that they were constituted of an HA matrix with small traces of tricalcium phosphate (β-TCP) phase. The XRD spectra were quite similar to those of commercial HA coatings. For coating to substrate adhesion two different tests were performed: adhesion tests according to ASTM C 633-79 and ASTM D 1002-83 standards. Higher values were obtained for ASTM C 633-79 than for ASTM D 1002-83, 35 and 15 MPa, respectively. This behavior is discussed in terms of the different stress effort applied to specimens. The results obtained with ASTM C 633-79 show that these double layered satisfy the stress requirements for load bearing biomedical applications. {\textcopyright} 1998 Published by Elsevier Science S.A.

	abstract = {Calcium phosphate materials are widely used in biomedical applications but their poor strength and brittleness limit their use in load bearing applications. To improve their mechanical properties, hydroxyapatite (HA) ceramics were reinforced with P                        2O

                        + oxides. A composite chemical composition that approaches the inorganic part of bone chemical composition was obtained using HA with calcium phosphate-based glasses. Fracture toughness was significantly enhanced by glass additions, and the decrease in fracture toughness at 1300 and 1350 {\textdegree}C was attributed to grain growth since it significantly increased with sintering temperature.
