Infrared coating stability evaluation system

Abstract

The invention relates to a stability evaluation system of an infrared coating, belongs to the technical field of coating damage judgment, and solves the problems of poor coating damage judgment accuracy, low efficiency and difficulty in accurate stability evaluation in the prior art. The data acquisition device is used for acquiring a full-wave band radiance diagram, radiance diagrams of two different wave bands and a blackbody radiance diagram of the infrared coating; the temperature distribution diagram obtaining module is used for obtaining a temperature distribution diagram according to the radiation brightness diagrams of the two different wave bands; the emissivity distribution diagram acquisition module is used for correcting the blackbody radiation brightness diagram according to the temperature distribution diagram to obtain a corrected blackbody radiation brightness diagram; obtaining an emissivity distribution diagram according to the full-band radiance diagram and the corrected blackbody radiance diagram; the damage judgment module is used for judging the damage of the infrared coating; and the coating stability evaluation module is used for obtaining the stability state of the infrared coating according to the obtained damage type of the infrared coating and the corresponding damage area.

Description

technical field [0001] The invention relates to the technical field of coating damage judgment, in particular to an infrared coating stability evaluation system. Background technique [0002] Infrared coatings refer to functional coatings used in specific fields to meet design requirements. They can be mainly divided into low-emissivity coatings, high-emissivity coatings, and adjustable emissivity coatings. Functional coatings usually have a thinner Thickness, and there is a large difference in radiation performance from the base material. During the use of the coating, it is often damaged due to operator intervention or environmental changes, etc., and its performance will be greatly reduced after the damage of the coating. Therefore, it is necessary to identify and analyze the damage state of the coating to ensure the coating The performance of the layer during use meets the requirements. [0003] The types of coating damage can be divided into peeling, air bubbles, crac...
