摘要

受钛植入物降解的临床问题的启发，我们开发了一套工作流程，可以评估表面氧化物动态与临床干预和炎症条件的关系。我们发现，机械损伤会导致钝化氧化膜中 TiO2 的化学计量比下降，并进一步导致炎症厌氧条件下的加速降解。这种方法可用于评估表面氧化物，以监测植入物的安全性。

Dynamic assessment of titanium surface oxides following mechanical damage reveals only partial passivation under inflammatory conditions

Motivated by clinical problems of titanium implant degradation, we developed a workflow that enabled assessment of surface oxide dynamics as a function of clinical interventions and inflammation conditions. We found that mechanical damage led to decrease of stoichiometric TiO2 ratio in the passivation oxide film and further resulted in accelerated degradation under inflammatory anaerobic conditions. This method can be employed for the assessment of surface oxides to monitor implant safety.

期刊介绍： npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
