比较了锌、铁和镁作为生物植入材料在磷酸盐缓冲液（PBS）中的长期腐蚀行为。比较的重点是腐蚀速率，模式，产品和表面特性沿着浸泡降解长达21天。对于瞬态测定，开路电位和腐蚀速率将Zn置于Fe和Mg之间。但在长期腐蚀过程中，锌的腐蚀速率比铁和镁的腐蚀速率快。这是由于其独特的局部腐蚀和腐蚀产物的变化，而不是铁和镁。(C)2016爱思唯尔有限公司版权所有。
The corrosion behavior of Zn was compared with those of Fe and Mg in a long-term course of immersing in phosphate buffered saline (PBS) as biodegradable metal for bio-implants application. The comparison focused on corrosion rate, mode, products and surface characteristics along the immersion degradation up to 21 days. For transient assays, the open circuit potential and corrosion rate placed Zn between Fe and Mg. However, in a long-term course the corrosion rate of Zinc developed faster than Fe and Mg. This was ascribed to its unique localized corrosion and corrosion products changing in contrast to Fe and Mg. (C) 2016 Elsevier Ltd. All rights reserved.
