Experimental study on influence of coating thickness on characteristics of temperature sensitive paint

摘要:
针对温度敏感涂料在模型表面喷涂时常面临的涂层厚度及其均匀性不可控的问题，研究涂层厚度对涂料特性的影响规律。以某型温度敏感涂料为研究对象，制备了4种不同涂层厚度的涂料样片；在自主建立的温度敏感涂料特性测量系统中，采用强度法测量了涂料样片的压力敏感性和温度敏感性。基于厚边现象定量分析了涂层厚度对测温不确定度的影响。结果表明：涂层厚度对涂料的温度敏感性和压力敏感性均影响显著，由涂层厚度造成的温度灵敏度和压力灵敏度最大相对变化幅度分别为7.7%和53.0%。当温度敏感涂料涂层厚度大于20 μm时，可大幅降低由涂层厚度变化造成的测量不确定度。实验过程中，需关注模型与校准实验样片表面涂层厚度的一致性，并明确最佳喷涂范围，以提升测量精度。
Abstract:Considering the problem that the coating thickness and its uniformity are uncontrollable when the TSP (temperature sensitive paint) is sprayed on the model surface, the influence of coating thickness on the TSP characteristics was studied. Based on a type of TSP, four samples with different coating thicknesses were prepared. The pressure sensitivity and temperature sensitivity of TSP samples were measured by intensity method in the self-built TSP characteristic measurement system. Based on the thick edge phenomenon, the influence of coating thickness on the uncertainty of temperature measurement was quantitatively analyzed. The results showed that the coating thickness exerted a significant impact on both the temperature sensitivity and pressure sensitivity of TSP. The maximum relative changes in temperature sensitivity and pressure sensitivity caused by coating thickness were 7.7% and 53.0%, respectively. The measurement uncertainty caused by the coating thickness can be significantly reduced when the coating thickness was greater than 20 μm. During the experiment, special attention should be paid to the coating thickness and its consistency with the calibration experiment. The optimal spraying range should be clarified to guarantee measurement accuracy.
