One of the main challenges in surface coating of silicon steel is achieving uniform and consistent coating thickness. This is crucial to ensure optimal performance and protection against corrosion. Another challenge is developing coatings that adhere well to the silicon steel substrate, as poor adhesion can lead to delamination and failure of the coating. Additionally, finding coatings that can withstand the high temperatures and harsh operating conditions experienced by silicon steel is a significant challenge. Lastly, cost-effectiveness and scalability of the coating process are important considerations, as the surface coating technique should be feasible for large-scale production of silicon steel.
