摘要
锁相红外涂层厚度检测技术具有非接触、面测量等优势,具有广阔的应用前景。制作变厚度涂层试件对锁相红外涂层厚度检测参数进行优化,建立了锁相红外涂层厚度检测标定曲线,制定了其涂层厚度检测合格要求与均匀性评价方法。最后,通过试验验证了基于锁相红外热成像技术的涂层均匀性评价方法的准确性和有效性。
Phase-locked infrared coating thickness detection technology has the advantages of non-contact and surface measurement,and has broad application prospects.In this paper,the phase-locked infrared coating thickness detection parameters were optimized by using variable thickness coating specimens,the phase-locked infrared coating thickness detection calibration curve was established,and the coating thickness detection qualification requirements and requirements based on phase-locked infrared thermal imaging technology were formulated.Finally,the accuracy and effectiveness of the coating uniformity evaluation method based on lock-in infrared thermal imaging technology were verified by experiments.
