Abstract

The present study focuses on the results of cavitation resistance research of samples obtained by the Selective Laser Sintering technology. The samples were made from polyamide powder reinforced with glass beads - PA 3200 GF. The laser-sintered samples were produced from 100% new and recycled powder mixed with 70% of new powder. The samples were tested under cavitation conditions using an ultrasonic vibration method with a stationary sample according to the ASTM G32 standard. Examination of the morphology of cavitation damage was investigated by scanning electron microscopy. The change in mass loss during different cavitation times was measured on the tested samples. The main objective of the research was to determine the validity of the application of the tested material in cavitation conditions.

选择性激光烧结制备pa3200gf材料的抗空化性能

本文主要研究了选择性激光烧结技术制备的样品的抗空化性能。样品由PA 3200 GF玻璃微珠增强聚酰胺粉末制成。激光烧结样品由100%的新粉末和回收粉末与70%的新粉末混合制成。根据ASTM G32标准，在空化条件下使用固定样品的超声振动法对样品进行测试。用扫描电镜观察了空化损伤的形貌。测量了不同空化时间下试样的质量损失变化。研究的主要目的是确定测试材料在空化条件下应用的有效性。

期刊介绍： Science of Sintering is a unique journal in the field of science and technology of sintering. Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published. Science of Sintering journal is published four times a year. Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
