激光感应复合快速熔覆（LIHRC）不仅可以提高熔覆效率，而且可以消除陶瓷-金属复合涂层的气孔和裂纹。为了更好地理解快速熔覆和高粉末沉积速率下的LIHRC，本文提出了Ni基WC复合涂层LIHRC的解析模型。该模型对熔覆层高度和粉末效率的预测与实验结果吻合较好。确定了激光功率衰减率较低的入射角，可获得表面光滑、轮廓良好、与基体冶金结合的无裂纹复合涂层。的粉末颗粒的温度的计算结果进行比较的显微硬度分布的实验数据，并显示出类似的趋势。
Laser induction hybrid rapid cladding (LIHRC) cannot only increase the cladding efficiency, but can also eliminate porosity and cracking of ceramic–metal composite coatings. In order to obtain a deep understanding of LIHRC with rapid cladding speed and high powder deposition rate, an analytical model of LIHRC for Ni-based WC composite coatings is proposed in the paper. The predictions of cladding height and powder efficiency obtained with this model are in good agreement with experimental results. Injection angles at which the attenuation rate of laser power is relatively low are identified and crack-free composite coatings with smooth surface, good profile and metallurgical bonding to substrate can be obtained. The calculated results for the temperature of the powder particles are compared to experimental data of the microhardness profiles and show a similar trend.
