Coating thickness detection and uniformity evaluation based on infrared thermography
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.
