| 摘 要： | 锻造LF6材料法兰硫酸阳极化后表面产生深灰色物质,影响产品质量和性能。分析认为这种现象与材料、机械加工和表面腐蚀有关,为此设计了一系列工艺验证试验,探寻深灰色物质产生的原因。试验结果表明,锻造LF6材料自身所含有的金属元素、机械加工和生产周期过长是阳极化封闭后零件表面产生深灰色的主要原因。

| Abstract: | Abnormal colour was observed on the surface of forged LF6 after being anodized with sulphuric acid,which effects quality and performance of the material. To determine the reason for this abnormal colour,a series of tests were designed and conducted. Tests results show that the main reasons of the abnormal colour are the metal elements of the alloy and the long period of processing. |
