After 2 weeks, the coating degraded gradually. After 3 weeks, some fish bone-like tissues are found on the surface of the coating. After 4 weeks, the coating degrade further. After 5 weeks, the coating is further degraded and exposed loose structure like dendrite. 6 weeks later, the surface of the coating appears some large holes. Microporous and holes can increase the contact area of the surface in SBF and promote degradation of the coating. ¸Ð¾õºÜ±ðŤ£¬Çë¸÷λ³æÓѰïæ·ÖÎöһϣ¡Ð¡µÜ²»Ê¤¸Ðл |
