中文摘要本发明公开了一种铝合金的超低温激光冲击强化方法,属于高性能铝合金技术领域。该方法是在合金试件表面覆盖吸收层后,再在吸收层上施加约束层约束激光冲击波增加冲击力;然后以脉宽为3‑40ns、波长为532nm或1064nm、激光能量为0.5‑20J、重复频率为0.1‑10Hz、光束直径为0.5‑10mm的激光束进行预冲击处理,接着将通过热传导方式对工件进行降温处理,保证试样在‑130±2℃的深冷环境下,然后以激光束进行冲击处理;本发明方法处理的铝合金试件表面显微硬度可提高30%以上,拉伸性能提高20%以上,且工艺简单,强化效果显著、效率高、成本低、无污染。
英文摘要The invention claims an aluminium alloy an ultra low temperature laser impact strength and method which belongs to high performance aluminum alloy the technology field of. The method is the alloy test piece covers the surface of absorbing layer and then the absorption layer is applied to constraint restraint layer laser shock wave increase the impact force; Then using pulse width is ns 3‑40 wavelength is irradiating 1064nm or laser energy is 0.5 ‑ 20j repeating frequency is 10hz- 0.1 ‑ beam diameter is 0.5 ‑ 10 of the laser beam to carry out impact treatment of the through hot conduction way to the work piece to reduce the temperature processing so as to ensure the sample in ‑ 130 less than the depth of the cold positive and negative environment and then laser beam to impact treatment; The invention claims a method for processing of aluminium alloy test piece is set on the surface of the micro hardness can be improved 30% more stretching and the performance is improved more than 20% it has simple process strengthening the effect is obvious the efficiency is high the cost is low without pollution.
