- 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.
