Searching for chromate replacements using natural language processing and machine learning algorithms

Abstract

The past few years have seen the application of machine learning utilised in the exploration of materials. As in many fields of research—the vast majority of knowledge is published as text, which poses challenges in either a consolidated or statistical analysis across studies and reports. To address this issue, the application of natural language processing (NLP) has been explored in several studies to date. In the present work, we have employed the Word2Vec model, previously explored by others, and the BERT model—applying them towards the search for chromate replacements in the field of corrosion protection. From a database of over 80 million records, a down-selection of 5990 papers focused on the topic of corrosion protection were examined using NLP. This study demonstrates it is possible to extract knowledge from the automated interpretation of the scientific literature and achieve expert human-level insights.

“…Moreover, stringent international health and safety regulations have been implemented, exemplified by the prohibition of chromates since September 2017 under the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation [24]. This has sparked extensive research to seek viable alternatives to chromates [4,[25][26][27]. Fortunately, several substitute inhibitors have been found and are already being incorporated into new coating systems.…”
