摘　　要：摆动阀式脉冲器具有载波频率高和传输速率高的特性。它的脉冲发生机构由摆动阀、泥浆分流器以及分流罩等零件组成,其中泥浆分流器是发生机构的核心部件,由金属基体与硬质合金插件黏结而成。根据过往作业经验得知,黏结工艺对泥浆分流器的寿命影响很大。重点研究黏结工艺中工艺参数对硬质合金与金属基体黏结力的影响,通过受力分析与试验验证得出影响因素,并优化工艺参数,使黏结胶层固化后表现出更佳的黏结性能。Shear valve pulser was a type of pulser have high carrier frequency and high transmission rate.The pulse generate end composed of valve rotor,flow divider,flow sleeve and other parts,the flow divider is the core component of the pulser,which is bonded by metal body and cemented carbide segments,and the advantages and disadvantages of the bonding process have a great impact on the life of the flow divider.This paper focuses on the details of the bonding process,the influence of process parameters on the adhesion between cemented carbide and metal matrix in the bonding process,and the performance of the adhesive and the force analysis of the adhesive layer are tested to optimize the improvement of the bonding process,so that the adhesive layer performs the best bonding performance after curing.
