脉冲电镀金刚石钻头试验研究

介绍脉冲电镀在人造金刚石孕镶钻头上的应用研究，探讨脉冲电镀机理，采用正交试验法优化脉冲电镀工艺参数；研制了脉冲电镀钻头，生产钻头周期缩短了３０％。在室内和野外生产试验中，发现脉冲电镀钻头较直流电镀钻头有如下优点：钻进地层适用范围广、钻进时效高。

TEST AND STUDIES ABOUT PULSE ELECTROPLATING DIAMOND

In this article the authors report some research results about pulse electroplating, applied in man made diamond impregnated bit, make research and discuss on mechanism of pulse electroplating, optimize pulse electroplating technological parameters by orthogonal experimental method. Some pulse electroplating bits are made. During the production process of them, it is found that the period of bit making is reduced by 30%. Tests in laboratory and production experiments in field show that the pulse electroplating bit has an advantage over direct current plating bit in more applicable for the drilled strata and higher average efficiency per hour.
