| 摘要: |
| 通过全浸腐蚀试验，乙酸盐雾试验等和X-射线扫描电镜微观形貌对比分析说明，我国北方地区高温雨季生产的部分表面斑状污黑铝绞线与正常铝绞线，在氧化膜微观形貌和构成、腐蚀行为及腐蚀速率方面基本一致。文中认为，其与我国南方所遇到的“表面斑状污黑铝绞线”一样，为“不影响使用、仅影响商业外观”的产品。 |

| Abstract: |
| The steel core aluminum twisted wire tends to be dark and flecked during the hot and rainy days in northern areas. This paper compares a dark and flecked wire with normal ones and finds that these samples have the same microstructure of oxide film, corrosion behavior and corrosion rate. So these flecked wires are the same as those occur red in southern areas. The defects on the surface only affect the commercial appearance but not their performance. |
| Key words: flecked and dark surface of steel core aluminum twisted wire,microstructure,corrosion behavior |
