摘　　要：以弱磁金刚石颗粒为第二相,采用电沉积法制备镍基弱磁金刚石工具。主要工序为:预处理,预镀镍,植砂(镀金刚石),去薄膜,严格的表面处理(包括电解除油、浸蚀、水洗等),补砂,加厚镀镍,开刃。所得金刚石工具中,胎体对颗粒包镶良好,金刚石颗粒分布均匀,尖端露出。切削试验表明,不同界面间的结合力显著提高,与无磁金刚石工具相比,弱磁金刚石工具的切削长度提高了51.8%。A nickel-based diamond-coated tool was prepared by electroplating using weak magnetic diamond particles as the second phase. The main processes are as follows： pre-treatment, nickel pre-electroplating, sand-planting （diamond electroplating）, thin film removal, strict surface treatment （including electrolytic degreasing, etching, washing, etc.）, supplement of sands, nickel electroplating for thickening the coating, and polishing to let the diamonds emerge from the surface. The diamond particles in the tool are embedded well by the nickel coating and distributed uniformly with their tips being exposed. The grinding test results showed that the adhesion between different interfaces is increased greatly. The cutting length of the diamond-coated tool prepared with weak magnetic diamonds is 51.8% higher than that of the one prepared with magnetism-free diamonds.
