如图所示,W、H和D分别代表着熔覆层截面的宽度、高度和深度,θ1和θ2分别代表熔覆层左右两侧的成形角度。熔覆层的稀释率η用熔深与熔覆层厚度(熔高和熔深之和)的比值来近似计算。
As shown in the figure, W, H and D represent the width, height and depth of the melt layer cross-section, respectively, and θ1 and θ2 represent the forming angles of the left and right sides of the melt layer, respectively. The dilution rate η of the molten layer is approximated by the ratio of the melt depth to the thickness of the molten layer (sum of melt height and melt depth).
