Enhancing the longevity of magnesium implants with cold-sprayed Ta/Ag coatings: Optimization of corrosion and wear resistance
No full textMagnesium alloys are gaining attention for biomedical implants due to their lightweight nature and bonemimicking mechanical properties. However, their high reactivity and vulnerability to corrosion restrict their long-term application in biomedicine. This study explores the potential of enhancing corrosion resistance and wear performance of magnesium through tantalum/silver (Ta/Ag) composite coatings manufactured by cold spray for durable implant devices. The coatings exhibited adhesive strengths ranging from 22.5 to 27.5 MPa, sufficient to prevent delamination. The inclusion of silver in the composites effectively protected the tantalum matrix from corrosion, preserving its structural integrity over a long period of corrosion. Additionally, a higher silver content improved fatigue wear resistance by inhibiting crack propagation and increased the hardness-to-Young’s modulus ratio through in-situ mechanical mixing of Ag and Ta during wear, which also reduced the generation of free debris particles. Among the tested compositions, the Ta–5Ag composite offered the best overall protection, optimizing corrosion resistance, wear performance, and mechanical stability. These results indicate that cold sprayed Ta/Ag composite coatings are a promising approach to making magnesium alloys more viable as long-term implant materials
Improved quantitative risk assessment of a natural gas pipeline considering high-consequence areas
No full textCurrently, quantitative risk assessment is often used for pipeline safety analysis. However, the low probability of pipeline failure may produce a false safety evaluation result because high-consequence areas with high population densities cannot be effectively identified. Furthermore, nearly half of the gas leakage accidents in China have occurred in densely populated areas. Therefore, an improved quantitative risk assessment method is proposed. First, we establish two models: (1) a failure probability model based on improved historical failure and disaster derivation probabilities and (2) a risk consequence model considering potential direct and indirect losses based on the probability of disaster evolution. Considering the concept of human rights equality and the social model of "life is first" in China, a method to correct the loss value of life according to population density is proposed, which can effectively avoid the hidden phenomenon of high-consequence areas mentioned above. A pipeline in China is evaluated using this improved method. Compared with traditional evaluation results, the new evaluation method can effectively identify a high-consequence area and obtain more reasonable results. Thus, a pipeline maintenance plan can ensure the interests of enterprises and fully respect the lives of individuals threatened by the potential risk of the pipeline
