In-situ SEM observation of crack propagation in Al2O3-ZrO2 APS and HVOF coatings

These images show failure propagation in Al2O3-ZrO2 coatings prepared by atmospheric plasma spraying (APS) and high-velocity oxy-fuel (HVOF). Fused and Crushed (F&C) and Agglomerated and Sintered (A&S) powders were used as feedstocks. Observation was carried out using Carl Zeiss EVO MA 15 SEM microscope and 3-point bending stage.

本数据集涵盖的图像展示了采用大气等离子喷涂（Atmospheric Plasma Spraying, APS）与高速氧燃料喷涂（High-Velocity Oxy-Fuel, HVOF）制备的氧化铝-氧化锆（Al₂O₃-ZrO₂）涂层的失效扩展过程。实验采用熔融破碎（Fused and Crushed, F&C）与团聚烧结（Agglomerated and Sintered, A&S）两种粉末作为原料。观测工作借助卡尔蔡司EVO MA 15型扫描电子显微镜（Scanning Electron Microscope, SEM）及三点弯曲加载台完成。相关研究论文：J.
