摘　　要：利用热浸镀在316L不锈钢基体上制备铝层,利用扫描电子显微镜、金相显微镜、划痕试验和盐雾试验对铝层微观组织和性能进行研究。结果表明,热浸镀时间对铝层的厚度和扩散层组织具有一定的影响规律。热浸镀铝层的膜基结合力达45 N以上,增强了316L不锈钢基体的防腐蚀能力。The microstructure and properties of Al thin films on 316L stainless steel, which were successfully deposited by hot-dipping method, were studied by SEM, metalloscope, scratch test and salt spray test. The results show that the film thickness and the diffusion layer are affected by the time of hot-dipping. The film-substrate cohesion is above 45 N, and the corrosive resistance of 316L stainless steel is improved after hot-dipping Al coating.
