Abstract In the present work, the modification of wetting properties of EB irradiated HA ceramics are studied under air and N2 gas atmospheres. We show a noticeable increase of the hydrophily of electron irradiated HA ceramics in an air gas atmosphere and a lesser increase when the samples are irradiated in an N2 atmosphere, such a phenomenon is correlated to a modification of grain morphology obtained under the 2 atm. With a progressive water saturation of the ceramics, the wetting angles increase progressively until they reach plateau values different from each set of samples (irradiated under air, irradiated under N2 atmosphere and pristine). Profilometry, SEM/EDX, XRD and Raman spectrometry analysis do not show differences between irradiated and pristine samples which indicates that the EB irradiation modifies the surface chemical elements related to the surface wetting properties and not those analysed by the above techniques.

电子辐照对羟基磷灰石表面性质的改性

摘要 在目前的工作中，研究了 EB 辐照 HA 陶瓷在空气和 N2 气氛下润湿性能的改变。我们显示在空气气氛中电子辐照 HA 陶瓷的亲水性显着增加，而在 N2 气氛中辐照样品时增加较少，这种现象与在 2 个大气压下获得的晶粒形态的改变有关。随着陶瓷的逐渐水饱和，润湿角逐渐增加，直到它们达到与每组样品不同的平台值（在空气下照射、在 N2 气氛下照射和原始）。轮廓仪，SEM/EDX，
