电弧喷涂铝对高强度螺栓摩擦型连接面抗滑移系数的影响

Effect of arc spraying aluminium on anti-glide coefficient of friction type high-strength bolt adjacent plane

利用电弧喷涂方法在高强度螺栓摩擦型接面上喷涂一层铝涂层。试验结果表明,该方法能明显提高高强度螺栓摩擦型连接面的抗滑移系数。同时,进行了在自然暴露环境下抗滑移系数随时间变化规律的测试。随时间的延长抗滑移系数在3个月内明显衰减;随后变化缓慢,趋向恒定值。

A test on the effect was carried out. The result shows that the antiglide coefficient of friction highstrength bolt adjacent plane is increased greatly by this method. The test of regularity of antiglide coefficient with time was conducted at natural exposure environment, the value of antiglide coefficicent reduces significantly within three months, then it changes slowly and tends to a constant.
