摘　　要：针对拉深不锈钢材料时影响模具使用的主要问题——粘着磨损问题,利用扫描电镜、硬度计、磨损实验机、X-射线衍射仪、能谱仪、光学显微镜等设备,通过考察NiSO4.6H2O、NaH2PO2.H2O、EDTA-2Na、C6H8O7.H2O、C3H6O3加入量对施镀后的镀层含P量、厚度、硬度、耐磨性、结合力、物相、形貌、能谱等的影响,获得了一种电刷镀优化配方,用其施镀可获得P含量(质量分数)为2%左右Ni-P镀层,该镀层经400℃左右的热处理后,与模具基材Cr12MoV有着良好的结合力,自身亦具有较高的硬度和良好的耐磨性.使用该配方和方法获得的镀层经生产验证,可以有效地解决模具的粘着磨损问题.Adhesive abrasion is the main factor that influences the die operation in the deep drawing of stainless steel materials. In order to solve this problem, SEM, hardometer, abrasion-testing machine, XRD, EDS and light microscope are adopted to investigate the effects of the addition of NiSO4.6H2O、NaH2PO2.H2O、EDTA-2Na、C6H8O7.H2O、and C3H603 on the phosphoric content, thickness, hardness, abradability, cohesion, phase, morphology and energy spectrum of the plating layer. An optimized formula for brush plating is also proposed. The results show that, by using the proposed formula, a Ni-P layer with a phosphoric mass fraction of about 2% can be obtained. The layer effectively sticks to the surface of Crl2MoV＇and possesses excellent hardness and abrasion-resistance after heating at 400℃. Practical application in factories reveals that the strengthened plating layer obtained by the proposed formula effectively avoids the adhesive abrasion of the die.
