抽象的。激光熔覆的过程可以描述为利用高能激光在模具表面快速熔化和沉积金属粉末，熔覆层具有满足模具表面要求的特殊性能。研究工艺参数对熔覆层几何形状的影响具有重要意义。为了更好地控制激光熔覆层的几何特征，提出了一种改进的数学模型，根据工艺参数(即激光功率、扫描速度、送粉速度和重叠率)预测熔覆层的高度和宽度。将预测结果与实验结果进行了比较，结果表明，该模型能够准确地预测熔覆层的高度和宽度。同时，对于单轨和双轨，该模型与实验测得的熔覆层高度和宽度吻合较好。因此，该模型可以指导激光熔覆过程的监控，特别是熔覆层高度和宽度的控制。
Abstract. The process of laser cladding can be described as the rapid melting and deposition of metal powder on the dieface by high-energy laser beam, and the deposited layer possesses specific properties which meet dieface requirements. It is of great significance to study the influence of process parameters on the geometry of cladding layers. To better control the geometric characteristics of laser cladding layer, a modified mathematical model is proposed to predict the height and width of cladding layers in accordance with process parameters (namely laser power, scanning speed, powder feeding speed, and overlapping rate). Then, a comparison of predictive results with experimental results shows that the proposed model can accurately predict the height and width of cladding layers. Meanwhile, this model is in good agreement with experimental height and width of cladding layers for single- and double-track. So, the model can guide the monitoring and controlling of laser cladding process, especially the control of cladding layer height and width.
