Abstract

The invention provides an in-situ test detection device and method for simulating corrosion and aging of a multi-factor atmospheric environment material. The in-situ test detection device is combinedwith technologies such as salt spray, electric heating, environment temperature and humidity control and ultraviolet radiation control. The method comprises: putting a metal material on a silicone rubber heating sheet in the experimental device, closing an optical path channel, heating the heating stage to a predetermined temperature by electrifying and heating the silicone rubber heating sheet, and sensing and controlling the temperature in real time through a temperature sensor; meanwhile, using the atmosphere temperature and humidity control device for realizing preset temperature and humidity in a test environment; quantitatively spraying salt mist to a sample at a fixed frequency in the test process, and an ultraviolet lamp irradiating the sample according to set radiation intensity and radiation frequency, so that the control simulation of five environmental factors including environmental temperature and humidity, sample temperature, salt mist and radiation is realized at the same time, the corrosion state of the sample in various atmospheric environments is reproduced, and real-time monitoring and detection conditions are provided.

Description

technical field [0001] The invention belongs to the field of material environmental testing, and relates to multi-factor reproduction and analysis of the corrosion process of materials such as metals, coatings and composite materials in various zones and various zones of atmospheric environments, under different temperature, humidity, salinity and radiation conditions. Tracking and monitoring to reveal the atmospheric corrosion behavior, law and mechanism of metal materials. Background technique [0002] Atmospheric corrosion is the corrosion of materials in the atmospheric environment. When a material is placed in an atmospheric environment, a very thin, invisible film of moisture (water film) usually forms on its surface. When the water film reaches a thickness of 20-30 molecules, it becomes the electrolyte film required for electrochemical corrosion. Atmospheric corrosion is mainly affected by the following factors: [0003] 1. Moisture [0004] Naturally occurring li...
