摘要:
对喷丸表面的复杂轮廓特征进行分析和表征，选取最能表征表面形貌的三维粗糙度参数，并探究其与材料硬度之间的关系。采用相同的喷丸工艺参数对316、420、2205 3种不锈钢进行喷丸处理，采用27个常用粗糙度参数进行表征，通过方差分析,找出最优形貌参数Sq，再结合Sa进行多尺度分析，得出最优评价尺度均为800μm。测量3种材料的原始表面硬度，结合各自的Sq值进行分析。结果表明，Sq是最优表面形貌参数，其最能表征喷丸表面的复杂轮廓特征， Sq与原始硬度之间存在反比关系，随材料硬度的增加而减小。
Abstract:
Analyze and characterize the complex profile features of the shot peening surface, select the three-dimensional roughness parameter that best characterizes the surface topography, and explore the relationship between it and the hardness of the material. Using the same shot peening process parameters for 316, 420, 2205 Three kinds of stainless steel were subjected to shot peening treatment, and 27 commonly used roughness parameters were used for characterization. Through variance analysis, the optimal shape parameter Sq was selected, and combined with Sa for multi-scale analysis, the optimal evaluation scale was 800 μm. Measurement 3 The original surface hardness of each material was analyzed in combination with their respective Sq values. The results showed that Sq is the optimal surface topography parameter, which can best characterize the complex contour features of the shot peened surface. There is an inverse relationship between Sq and original hardness, and the decrease with increasing material hardness.
