Korosi pada baja adalah masalah utama di industri, terutama di lingkungan korosif. Salah satu solusi efektif adalah penggunaan lapisan pelindung (coating) yang dapat memperlambat korosi dan meningkatkan ketahanan struktural. Penelitian ini mengulas pengaruh ketebalan lapisan terhadap ketahanan korosi baja dalam kondisi ekstrem. Hasil menunjukkan bahwa ketebalan lapisan antara 80μm hingga 300μm memberikan hasil terbaik, sementara lapisan yang lebih tebal dapat menyebabkan keretakan. Jenis coating seperti epoksi dan zinc, serta aditif seperti fosfonat, juga meningkatkan ketahanan korosi. Persiapan permukaan yang optimal, seperti abrasive blast cleaning, meningkatkan adhesi dan kinerja lapisan. Penelitian ini menyarankan kombinasi ketebalan lapisan yang tepat dan teknik persiapan permukaan yang efektif untuk perlindungan maksimal, serta perlunya penelitian lanjutan untuk mengembangkan pelapis yang lebih efisien dan ramah lingkungan.
