摘要: The overlapping effects on surface roughness are studied when samples treated by laser shock peening (LSP). Surface of overlapped circular spot is calculated ISO 25178 height parameters. usually used styles namely isosceles-right-triangle-style (AAP) and equilateral-triangle-style (AAA) carefully investigated the degree in x-axis (ηx) below 50%. attains its minimum value at ηx 29.3%, maximum 43.6%. 42.3%, 32%. Experimental results well consistent with theoretical analysis.
