Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The following examples provide detailed operating procedures, but the implementation scope of the present invention is not limited to the following examples.

[0055] figure 1 It reflects the specific flow of a metal atmospheric corrosion rate prediction algorithm based on the mass transfer kinetic model, which is suitable for environmental factors such as temperature, humidity and salt spray concentration (or salt spray deposition rate, which are related) as the main influencing factors The prediction of the atmospheric corrosion rate of metals is more suitable for the calculation of corrosion rates in marine environments such as semi-enclosed (air can circulate, but there is no need to consider sunlight).

[0056] The occurrence of atmospheric corrosion in the marine environment begins with the deposition of sea salt particles on the surface...

Abstract

The invention discloses a metal atmospheric corrosion rate prediction algorithm based on a material transfer kinetic model, which is suitable for metal atmospheric corrosion rate prediction taking environmental factors such as temperature, humidity and salt spray concentration as main influence factors, and comprises the following steps of: S1, measuring and calculating key environmental factors influencing a corrosion rate; S2, performing conversion calculation on the environmental factors to obtain theoretical values of the related parameters in the step S3; and S3, speculating and calculating the corrosion electrochemical reaction rate according to the dissolution and diffusion model of the oxygen under the liquid film, namely a substance transfer kinetic model. The dynamic model between metal atmospheric corrosion and meteorological factors is established on the basis of the existing mature metal corrosion electrochemical theory and thermodynamic law, the atmospheric corrosion of each region can be calculated according to meteorological environment data, and theoretical support is provided for drawing a corrosion map; and effective guidance can be provided for metal corrosion prediction, corrosion prevention and other aspects.

Description

technical field [0001] The invention relates to the field of metal corrosion and anticorrosion, in particular to a metal atmospheric corrosion rate prediction algorithm based on a material transfer dynamics model with environmental factors as the main influencing factors. Background technique [0002] Due to the harsh environment of high temperature, high humidity and high salt spray in the marine climate, electrical equipment operating in this environment is prone to corrosion, causing electrical performance degradation, failure and other problems, seriously affecting the safe operation and service life of the equipment. Establishing a physical corrosion model of metal materials based on factors affecting the corrosion environment is not only of academic value, but also in terms of atmospheric corrosion prediction for engineering construction, calculation and determination of atmospheric corrosion in various regions based on meteorological and other environmental data, and e...
