Cavitation-induced wear, also known as cavitation erosion, can be found in many fluid power components, especially in water hydraulics. Cavitation erosion leads to component damage and might even cause system failure. The resistance of various materials to cavitation erosion when using conventional manufacturing processes has already been investigated in the past. In this work, the effects of additively manufactured materials on the resistance to cavitation erosion are investigated and compared to effects after conventional manufacturing. Also, the influence of the build-up direction of the additively manufactured specimens on cavitation erosion is determined. As the main indicators of cavitation erosion, mass loss and the surface structure are determined for all specimens.

增材制造材料的抗空蚀性

气蚀引起的磨损，也称为气蚀，可以在许多流体动力部件中找到，尤其是在水液压系统中。气蚀会导致部件损坏，甚至可能导致系统故障。过去已经研究了使用传统制造工艺时各种材料对气蚀的抵抗力。在这项工作中，研究了增材制造材料对抗气蚀的影响，并与传统制造后的影响进行了比较。此外，还确定了增材制造样品的堆积方向对空蚀的影响。作为气蚀的主要指标，质量损失和表面结构被确定为所有样本。
