A kind of method for optimizing metal foam preparation process and preparation method of metal foam

Abstract

The invention discloses a method for optimizing the preparation process of foamed metal, which comprises: using an online visual inspection system to obtain current microstructure characteristic data of foamed metal; The product performance and microstructure correlation model is used to calculate the product performance gap of the foam metal corresponding to the current microstructure feature data; the product performance and microstructure correlation model of the foam metal is used to calculate the target value of the microstructure feature, and iteratively calculate whether the performance can be achieved. target value; according to the target value of the microstructure characteristics, use the correlation model between the preparation process and the action mechanism to calculate the process parameters that should be adjusted; according to the calculated process parameters, adjust the equipment to prepare the foam metal material; The microstructural features are inferred from the microstructural correlation model, and the process parameters are iteratively fine-tuned based on the differences from the target microstructural features.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a method for supporting the optimization of foam metal preparation technology and a preparation method of foam metal. Background technique [0002] The preparation of metal foam by electrodeposition refers to the deposition of target metals or alloys by electrodeposition after the surface conduction treatment of three-dimensional structural materials with high porosity (such as plastics, polyurethane foams, etc.; called electrodeposition precursors). , and then remove the polymer precursor by heat treatment, and after reduction annealing, the metal foam material can be obtained. [0003] The preparation process of the electrodeposition method mainly includes substrate preparation, conductive treatment, electrodeposition, substrate burning, reduction, heat treatment, etc. At present, it is difficult to accurately describe the relationship between each process parameter and the p...

Problems solved by technology

[0003] The preparation process of the electrodeposition method mainly includes substrate preparation, conductive treatment, electrodeposition, substrate burning, reduction, heat treatment, etc. At present, it is difficult to accurately describe the relationship between each process parameter and the performance of the final product, and it is impossible to accurately describe the relationship between each process parameter and the performance of the final product. Correspondingly adjust the production process to ensure product quality or adapt to different application requirements, resulting in poor uniformity and large performance dispersion of metal foam prepared by traditional processes
