抄録
Hydroxyapatite coatings were sprayed on 304 stainless steel substrates by using a gas tunnel type plasma system (GTTP). This system consists of two plasma sources: a gun which produces internal low power plasma (1.3-8 kW) and vortex which produces external high power plasma (10-40 kW). In this work, the arc gun current was changed while the vortex arc current was kept constant at 450 A. The effect of gun power on the microstructure and mechanical properties of HA coatings were investigated. Five gun currents were adjusted (0, 30, 50, 70 and 100 A) at the same vortex current (450 A) for sprayed HA coatings. The microstructure of resulting coatings was investigated by XRD and SEM. Hardness values of HA coatings sprayed at different arc gun currents were also investigated. The results showed that the gun currents affected the microstructure and porosity of HA coatings. Moreover, the hardness was slightly decreased as the gun current increased.
