The phosphated zinc layer was post-sealed with molybdate to obtain the composite coating without *** composition of the formed coating was investigated. The corrosion behavior of the coated samples was *** coated samples were first scratched and subsequently corroded in a neutral salt spray( NSS) chamber for 2-72 h; the microstructure of the corrosion products was analyzed via SEM and EDS; and the self-healing performance was discussed. The coating obtained contains Zn_3( PO_4)_2· 4H_2 O,Mo_2O_3 and MoO_4^(2-). The electrochemical impedance first increases and then decreases with the immersion time. However,after immersion for 6 days,it remains at about 10 kΩ·cm^2,much higher than the value for the single-treated samples without corrosion. Micro structural observations show that the corrosion products in scratch increase in size and finally cover the whole scratch completely. The initial corrosion products have high P,Mo and O contents but almost no Cl,while in later stages the first three components decrease and Cl increases. The corrosion products form a compact mass of needle-like crystals,effectively inhibiting zinc corrosion. The composite coating exhibits good self-healing.

在临床实践中,红细胞输注需要参考患者的血红蛋白浓度水平,但不同指南推荐的红细胞输注启动阈值都不尽相同。这些不同范围的存在导致输血启动的时机也仍有争议。同时,使用异体血制品就存在着一定发生输血相关感染性损伤或器官损伤的风险,因此启动红细胞输注需要更多循证医学证据。本文综述了中心静脉氧饱和度、动静脉氧差和近红外光谱法这3种新指标以及围术期输血指征评分等新方法来帮助评估输血指征,为临床医生进行输血决策提供参考。
