Abstract

Novel smart coating systems, developed through extensive research, are revolutionizing corrosion protection, extending the lifespan of metal structures. Magnesium, known for its strength and biodegradability, is an ideal material for implants. Its alloys closely match human bone properties, but challenges like systemic toxicities arise from alloying. Surface modifications, such as biocompatible coatings, address degradation issues in orthopedic implants. Traditional methods like chromate conversion coatings for Mg alloys introduce systemic toxicity due to hexavalent chromium. Polymeric materials are used for degradable implants but are limited to low load-bearing parts due to lower mechanical strength. Recent biomimetics research has led to the creation of intelligent multifunctional coatings, inspired nature. These bioinspired coatings, mimicking nature, enhance anticorrosion efficiency. This review offers a comprehensive overview of published reports on bioinspired coatings, showcasing their state-of-the-art applications for safeguarding metal substrates against corrosion.
