摘要
开展了飞秒激光加工不锈钢的具体试验。通过设置不同工艺参数,研究单因素试验中不同变量对表面微结构各项指标的影响规律,并分析总结其形成机理;进一步设计正交试验,通过改变工艺参数获得形貌不同的矩阵阵列微结构,并对多因素下表面综合加工情况进行了研究,归纳各因素对微结构深度、宽度及粗糙度的影响规律;对结果进行极差分析,确定影响最大加工因素,得出设定参数内最优加工水平工艺。
The specific experimnt of femtosecond laser processing stainless steel was carried out.By setting different process parameters,the influence law of different variables on various indexes of surface microstructure in single factor experiment is studied,and its formation mechanism is analyzed and summarized;The orthogonal experiment was further designed,the matrix array structures with different morphologies were obtained by changing the process parameters,the comprehensive surface processing under multiple factors was studied,and the effects of various factors on the depth,width and roughness of microstructure were summarized;The range analysis of the results is carried out to determine the most influential processing factors,and the optimal processing level within the set parameters is obtained.
