摘　　要：针对沿海地区高腐蚀环境,对钢结构件进行了多元金属热扩渗-锌镍渗层处理。测试结果显示,热扩渗方式制备的锌镍渗层不仅有优良的防腐性能,还具有不降低材料力学性能、良好的抗冲击性能、适宜的表面硬度和与混凝土结合的握裹强度。在沿海地区实际服役效果表明,多元金属热扩渗-锌镍渗层有优于其他表面防护技术的防腐性能。In view of the high corrosion environment in coastal areas, the steel structural parts were treated with multi-metal thermal diffusion infiltration-zinc-nickel infiltrated layer(ZNIL). The test results show that the ZNIL prepared by thermal diffusion infiltration not only has excellent corrosion resistance,but also has no reduction in material mechanical properties, good impact resistance, suitable surface hardness and grip strength combined with concrete. The actual service effect in coastal areas shows that the multi-metal thermal diffusion infiltration-ZNIL has better anti-corrosion performance than other surface protection technologies.
