Abstract

Thermodynamic calculation for main reactions happening in the process of fabricating hydroxyapatite(HA) composite coating by laser cladding using the mixture of the calcium carbonate (CaCO3) and calcium hydrogen phosphate dihydrate (CaHPO4•2H2O) is carried out to obtain a high content of HA in coating. The experiments are conducted to verify the thermodynamic analysis and find ways to optimize process parameters. It indicates that HA can be obtained when the temperature is below 1500K, and the CaTiO3 is easier to form when the temperature exceeds 1300K.
