The corresponding wave-absorbing coating thickness data were obtained through 25 sets of wave-absorbing coating spraying experiments. The range analysis,variance analysis and nonlinear regression analysis were made for the thickness data of wave-absorbing coating. The result shows that the influences of spraying process parameters on the thickness of wave-absorbing coating are sorted in descending order:spraying speed> stepping distance> spraying distance> paint viscosity> spraying angle> spray gun air pressure. The spraying speed has a significant effect on the thickness of wave-absorbing coating. A regression model for predicting the thickness of wave-absorbing coating was established. It can accurately characterize the quantitative relationship among the wave-absorbing coating thickness and the spraying process parameters. %U http://www.co-journal.com/EN/10.3969/j.issn.1000-1093.2021.12.017
