| 中文摘要: |
| 目的 检查不锈钢零件环形内腔表面的清洁度水平。方法 通过采用预清洗和高压水射流清洗的联合方法对某不锈钢零件环形内腔表面进行清洗，并借助专用夹具不断冲洗环形内腔表面，直至目视检查清洗车底部的滤网内没有可见的杂质，然后收集全部清洗液进行清洁度检查，采用3 μm的滤纸过滤收集的清洗液。结果 用分析天平称杂质质量为1.5 mg，用金相显微镜检查，硬颗粒尺寸均小于0.1 mm。结论 通过该方法能够满足某不锈钢零件环形内腔表面清洁度C级检测要求。 |

| Objective Toverify the cleanliness level on the inner cavity surface of stainless steel parts. Methods The inner cavity surface of stainless steel parts were washed with pre-cleaning and washing high pressure water jet. The inner surface was washed continuously under dedicated tooling until there was no impurity visually on the filter screen at the bottom of cleaning tank. The cleaning solution was collected for cleanliness verification. The collected cleaning solution was filtered with 3 μm filter paper. Results The weight of impurity was 1.5 mg with analytical balance, and the size of hard particles was less than 0.1mm under metallographic microscope. Conclusion Class C level of cleanliness can be archived by above method for inner cavity surface on stainless steel parts. |
