采用胶粘剂把不同表面粗糙度的Q235钢粘合到一起,对粘合镀层的拉伸强度和剪切强度进行研究。结果表明,拉剪强度随Q235钢表面粗糙度的变化不断地发生变化,出现了波谷和波峰。
The Q235 steel with different surface roughness was bonded by adhesive to study the tensile strength and shear strength of the bonding coating. The results show that the tensile strength varies with the surface roughness of Q235, and the troughs and peaks appear.
