摘　　要：电刷镀非常适合于大型模具的现场修理,在常用刷镀层中,镍层、镍钨钴合金及某些复合刷镀层一般难以满足大型模具的综合性能要求,而镍磷镀层是一种通过热处理可以改善其性能的镀层.作者通过研究热处理对不同磷含量的镍-磷镀层硬度、耐磨性、耐蚀性及结合强度的影响规律发现,含磷2%左右的镍磷镀层通过400℃左右的热处理后具有最佳的硬度、耐磨性和结合强度,而含磷10%左右的镍磷镀层经600℃左右的热处理后具有最佳的耐蚀性能,这可以为电刷镀在大型模具的修理方面针对不同的使用要求提供合适的镀层和热处理方法.Brush-plating is specially fit for large-sized die repair in the job site. The common used brush-plating layers, such as Ni layer, Ni-W-Co layer, composite deposit, are difficult to meet the large-sized die combination property requirement. However, the Ni-P layer is a layer which performance can be improved by heat treatment. Through research the influence rule of heat treatment to Ni-P layer in differentphosphoric content rigidity, abrasion-resistance, erosion-resistance and adhesion strength, this paper discovers that contenting phosphoric about 2 % layer has best rigidity, abrasion-resistance, adhesion strength after 1 hour heat treatment in 400℃ and about 10% layer has best erosion-resistance. This conclusion help to select proper layer and heat treatment method for different large-sized die brush-plating repair.
