Description
发明领域
本发明所涉及的领域是采用热熔镀铝护层的方法来防止锻件，生铁及钢部件的腐蚀。
发明背景
众所周知在钢部件表面热熔镀铝护层，其铝合金熔液中含有锌和镁。
类似的发明也是在生铁部件和钢部件表面热镀铝护层，包括部件表面处理，在热熔铝合金中浸镀，热熔铝合金液中含有合金锌和合金硅(GB，№ 1440328，M П К C23 C 1/00，1976 г.)。
应当指出的是，这些方法的不足在于，当温度低于715℃时，不采用助熔剂，在生铁部件和钢部件表面热镀铝护层是不可能的，而在金属之间形成的过渡层的厚度相当大(10-15 M К M)，导致护层脆弱，不能进一步形成钢铝合金护层。
发明内容
本发明所取得的技术成果包括降低热融合金的温度，不采用助熔剂在较低的温度下形成相当均匀，可塑性良好的护层，从而形成钢铝合金护层。
本发明的技术成果就在于在生铁部件和钢部件表面热浸镀铝，其中仍包括部件表面处理，在热熔铝合金中浸镀，合金中含有锌和硅，但表面处理采用喷丸技术，而铝合金中既含有锌，硅，还有镁和锡，其含量％如下：
锌 7.0-10.0
硅 3.0---5.0
镁 0.5---1.5
锡 0.2---0.5
合金的最佳温度在660℃至680℃之间。
用喷丸技术表面处理的试样，在不同化学成分的铝合金中热浸镀，其护层结构和护层特性见表1。
护层的可塑性是采用镀层试样在圆柱体周围弯曲的方法检验。在表1中有最小的弯曲直径，按照该直径缠绕时护层没有受到损坏。护层防腐特性试验是在塑料薄膜里含有氯离子(仿海洋性气候)人工气相条件下，进行的快速老化试验的方法。
用电化学研究方法研究所获得护层的结果表明，含有锌，硅，镁和锡的铝合金大大提高护层电极势测量结果的还原性，证明护层表层化学成分的高度一致性。
经过表面喷丸处理的试样，在不同温度条件下进行热浸镀，铝合金熔液化学成分是：铝---主要成分，锌---8.0％，硅---4.5％，镁---1.1％，锡---0.4％，其试验结果见表2。
研究还表明，在660℃--680℃温度阶段，不采用助熔剂而形成的铝合金护层密致和厚度均匀，具有高度的耐腐蚀性和可塑性。
在各种化学成分和不同时间进行镀铝(表1，表2)的分析结果还表明，经过表面喷丸处理的钢试样，不使用助熔剂，在铝合金成分为铝-主要成分，锌- 7.0-10.0％，硅- 3.0-5.0％，镁-0.5-1.5％，锡- 0.2-0.5％，合金熔液温度在660-680℃阶段，可达到预期目的。不采用助熔剂，在所建议的铝合金成分的熔液中，在所建议的温度段进行热浸镀，可以得到厚度均匀，结构可挠性良好，具有高度耐腐蚀性的镀铝护层。
