摘　　要：提出一种新型可降解软磨料用于磨料水射流清洗技术,分析对比不同硬度磨料水射流清洗再制造零部件的清洗性能和表面损伤规律.采用石榴石硬磨料水射流、核桃壳软磨料水射流和纯水射流3种射流方式,开展清洗零部件污垢的对比试验;在不同清洗方式下,分析清洗速率、比能耗、清洗后表面粗糙度、最大坑深等4个方面的差异,并从宏观和微观层面分析不同清洗模式下基体损伤情况.结果表明,核桃壳软磨料能够有效去除表面污垢和杂质,降低比能耗,提高清洗速率,同时又不会对基体表面产生较大的损伤,在再制造业清洗或对表面粗糙度要求高的场合下,是一种较为理想的选择.This study proposes a novel degradable soft abrasive for abrasive water jet cleaning technology and analyzes and compares the cleaning performance and surface damage patterns of remanufactured components treated with the abrasive water jet of varying hardness.Furthermore,the study conducts comparative experiments on the cleaning of component dirt using three different jet methods:garnet hard abrasive water jet,walnut shell soft abrasive water jet,and pure water jet.The study analyzes the differences in cleaning rate,specific energy consumption,surface roughness after cleaning,and maximum pit depth among different cleaning methods,and investigates the matrix damage under different cleaning modes from both macro and micro perspectives.The results show that the walnut shell soft abrasive demonstrates superior cleaning efficacy,reduced specific energy consumption,improved cleaning speed,and negligible substrate surface damage.Consequently,the walnut shell soft abrasive is regarded as an ideal cleaning choice in remanufacturing industries or for applications that demand high surface roughness standards.
