摘要
介绍了一种能使铝锅具备导磁性能的表面处理工艺。首先对铝锅进行喷砂处理，使其外表面的粗糙度Ra达到2.5-5.0μm，再电弧喷涂一层可导磁的铁涂层，并对铁层进行砂光处理，最后喷涂高温有机硅树脂保护涂层。经测试，铁涂层平均膜厚为207μm，表面孔隙率为1.28%，平均断裂载荷为21109.48 N，平均断裂强度为41.66 MPa；有机硅涂层的附着力、耐溶剂性、耐热性良好。最终产品的导磁性能达到企业标准。
A surface treatment, which enables aluminum cooker get electromagnetic induction, was introduced. The process mainly includes： sandblasting to achieve a surface roughness Ra of 2.5-5.0μm, electric arc spraying to form an iron coating, polishing, and spraying with a high-temperature silicone resin coating. The test results showed that the iron coating has the following properties：average thickness 207μm, surface porosity 1.28%, average breaking load 21 109.48 N, and average fracture strength 41.66 MPa. The organic silicon coating has good adhesion strength, solvent resistance, and thermal resistance. The electromagnetic induction performance of the cooker meets the enterprise standard.
