采用等离子体增强化学气相沉积(PECVD)技术在WE43合金表面制备了用于生物医用的SiH4非晶硅薄膜。用掠角X射线衍射仪(GAXRD)、X射线光电子能谱(XPS)和俄歇电子能谱(AES)对薄膜的微观结构和成分进行了分析。浸泡实验表明，硅膜能有效地减缓WE43合金在37+/-1℃模拟体液中的降解速率。对WE43合金进行了溶血试验和血小板粘附性试验，结果表明，WE43合金表面包覆硅后，溶血率降低，附着在硅膜上的血小板呈圆形失活状态。(C)2012爱思唯尔B.V.保留所有权利。
Amorphous Si film was prepared by plasma enhanced chemical vapor deposition (PECVD) of SiH4 on WE43 alloy for biomedical application. The microstructure and the composition of the film were investigated by glancing angle X-ray diffraction (GAXRD), X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES), respectively. The immersion test indicated that Si film could efficiently slow down the degradation rate of WE43 alloy in simulated body fluid (SBF) at 37+/-1 degrees C. MTT assay suggested that the extract of the Si coated WE43 alloys was harmless to murine fibroblast cells (L 929). Hemolysis test and blood platelets adhesion test were conducted, and the results show that the hemolysis of WE43 alloy decreased after being coated by Si and the platelets attached on the Si film were at the inactivated stage with a round shape.
