使用摩擦搭接接合将聚酰胺6和聚乙烯板与普通碳钢（SPCC）板进行异种材料接合。聚酰胺6和SPCC板可以通过摩擦搭接直接连接，而聚乙烯和SPCC板不能。聚乙烯表面的电晕放电处理使得能够与SPCC形成接头。拉伸剪切断裂载荷的SPCC/聚酰胺6和SPCC/电晕放电处理的聚乙烯接头增加与连接速度高达600毫米分钟，超过它下降。这些接头在拉伸剪切试验中以最佳连接速度在塑料板的基材处断裂。通过截面显微组织分析观察了这些材料的连续连接界面。透射电子显微镜和选区衍射图表明，这些材料通过由Fe 3 O 4组成的SPCC的表面氧化层连接。拉伸剪切断裂载荷和XPS分析结果之间的关系表明，极性基团，如酰胺，羟基和羧基的塑料表面上的SPCC/塑料接头的接头形成是非常有效的。
Dissimilar material joining of polyamide 6 and polyethylene plates to a plain carbon steel (SPCC) plate was performed using friction lap joining. The polyamide 6 and SPCC plates could be directly joined by friction lap joining, whereas the polyethylene and SPCC plates could not. Corona discharge treatment of the polyethylene surface enabled the joint formation with SPCC. The tensile shear fracture load of the SPCC/polyamide 6 and SPCC/corona-discharge-treated polyethylene joints increased with the joining speed up to 600 mm min, beyond which it decreased. These joints were fractured at the base material of the plastic plate at optimal joining speeds in the tensile shear test. Continuously joined interfaces of these materials were observed via cross-sectional microstructure analysis. Transmission electron microscopy and selected area diffraction patterns indicated that these materials were joined through the surface oxide layer of SPCC composed of Fe3O4. The relation between the tensile shear fracture loads and the results of XPS analysis indicated that polar groups such as amide, hydroxyl, and carboxyl groups on the plastic surfaces were highly effective for joint formation of the SPCC/plastic joints.
