Embodiment

[0050] The present invention is a method for analyzing the dynamic evolution of nickel-based alloy corrosion layer based on cellular automata, which includes analysis of each cell and actual alloy samples in corrosion experiments. The method includes the following steps:

[0051] Step 1: Based on the actual shape of the alloy sample, select a corresponding coordinate system, define a two-dimensional cell space, select Margolus-type neighbors, and determine periodic boundary conditions;

[0052] Step 2: according to the composition of the chloride molten salt and the alloy, define the properties of different lattice positions in the cell space;

[0053] Step 3: Define the evolution rules in the cellular automata space, realize the mutual conversion between cells in the cellular automata space, and convert the evolution rules into programming language through MATLAB software;

[0054] Step 4: Set an appropriate simulation time step, and use the two-dimensional cellular automata ...

Abstract

The invention discloses a nickel-based alloy corrosion layer dynamic evolution analysis method based on a cellular automaton. Each step of chemical reaction is converted into a corresponding programming language for expression, so that a model is more consistent with an actual situation; meanwhile, a change curve of the thicknesses of a total corrosion layer, an outer corrosion layer and an inner corrosion layer can be obtained, and the corrosion layer thickness change condition of the alloy under long-term corrosion can be predicted. The mass loss trend of the alloy can be predicted through the change trend of the total corrosion layer thickness, and the two are combined, so that the purpose of predicting the service life of a metal structure pipeline and a container can be achieved.

Description

technical field [0001] The invention belongs to the technical field of cellular automata evolution research, in particular to a method for analyzing the dynamic evolution of nickel-based alloy corrosion layers based on cellular automata. [0002] technical background [0003] In concentrating solar power plants, heat transfer and heat storage systems are the main parts, which directly affect the working efficiency and cost of the system. Chloride molten salt has become an excellent heat transfer and heat storage material because of its large heat capacity, low viscosity, high operating temperature, wide temperature range, good thermal stability and low cost. However, at high temperatures, chloride molten salts are highly corrosive to metallic structural materials such as pipes or vessels. It is difficult to study the corrosivity of chloride molten salts, the experiment period is long and it is difficult to study the corrosion process, so some scholars choose to use advanced ...
