Published Date: 12/07/2024

A machine learning framework to accelerate the development of sustainable corrosion inhibitors for aluminum alloys.

The development of effective and environmentally friendly corrosion protective technologies has become a pressing need in various industries. Aluminum alloys, widely used in automotive, aeronautical, infrastructure, and electronics, are susceptible to corrosion, which can lead to catastrophic accidents and structural collapse. The limitation of chromate-based corrosion inhibitors has driven research towards the development of high-throughput testing methodologies and databases of organic compounds. The application of machine learning (ML) and data-driven approaches has enabled the development of more effective and sustainable corrosion protective technologies.

Seminal ML works have focused on a few dozen inhibitors for aluminum alloys, testing a combination of ML algorithms and features to describe the molecules. These approaches have evolved into robust ML models that consider a larger number of corrosion inhibitors. The use of composite models, which incorporate data from different sources and conditions, has the potential to increase the chemical space considered in the models and improve their performance.

However, the development of composite models poses several challenges, such as dealing with results from different techniques, different conditions, higher data variability, and data uniformization. To overcome these challenges, it is essential to develop a robust framework that can effectively integrate data from different sources and conditions.

In this article, we propose a machine learning framework that can accelerate the development of sustainable corrosion inhibitors for aluminum alloys. The framework combines data from different sources and conditions, including experimental and computational data, to develop a comprehensive understanding of the relationships between molecular structures and corrosion inhibition efficiencies.

The proposed framework has the potential to revolutionize the field of corrosion inhibition by enabling the rapid discovery of new, sustainable corrosion inhibitors. This can have a significant impact on various industries, including automotive, aerospace, and construction, by reducing the environmental footprint of corrosion protection technologies.
