The effect of different treatments for preparing implant materials was examined by scanning electron microscopy and by contact angle measurements. The materials examined were Ti6A14V alloy, Co-Cr-Mo alloy, A12O3, and synthetic hydroxyapatite. Samples were prepared with solid or porous surfaces of these materials. These were detergent-cleaned and then either autoclaved (steam sterilization), radiation-sterilized, nitric acid-etched, or plasma-cleaned. The results of wettability studies indicated marked changes in surface energy corresponding to the different preparation methods, and differences in surface morphology were also observed. These differences could have significant consequences on in vivo implant behaviour as mediated by tissue-implant interactions.
通过扫描电子显微镜和接触角测量来研究不同处理方法对植入材料制备的影响。所研究的材料包括Ti6A14V合金、钴铬钼合金、Al2O3和合成羟基磷灰石。制备了这些材料的固体或多孔表面的样品。对这些样品进行洗涤剂清洗，然后分别进行高压灭菌（蒸汽灭菌）、辐射灭菌、硝酸蚀刻或等离子体清洗。润湿性研究结果表明，对应于不同的制备方法，表面能有显著变化，并且还观察到表面形态的差异。这些差异可能会对由组织-植入物相互作用介导的体内植入行为产生重大影响。
