摘要
采用光纤激光构造铝合金表面微孔阵列结构,采用有限元方法分析了扫描速度和激光功率对激光表面热处理温度场的影响,并对铝合金和塑料间的连接强进行测试。结果表明:工件表面的温度随激光扫描速度的增大而减小;随着激光功率的增大,工件表面温度提高;随着激光功率的增大,铝合金与塑料间的连接强度呈先升高后降低趋势,当激光功率为50w时,连接强度达到最大值。
the microporous array structure on the surface of aluminum alloy is constructed by optical fiber laser.The effects of scanning speed and laser power on the temperature field of laser surface heat treatment are analyzed by finite element method,and the connection strength between aluminum alloy and plastic is tested.The results show that the temperature of workpiece surface decreases with the increase of laser scanning speed;The temperature field on the workpiece surface increases with the increase of laser power;The connection strength between aluminum alloy and plastic first increases and then decreases with the increase of laser power.When the laser power is 50 W,the connection strength reaches the maximum.
