AUTOCATALYTIC COMPOSITE COATINGS IBD

Sinopse

Ship structures such as waterjet suction pipes, strainers, and seawater pump intake ducts, made from high-strength AH36 steel, endure cyclic loading and harsh marine conditions. This book focuses on designing and synthesizing superior ENi-P-nano TiO2 coatings with the incorporation of C14-SB zwitterionic surfactant on AH36 steel. Taguchi-based experiments were conducted to achieve optimal hardness in the coatings using the best combinations of input parameters. Surface compatibility for marine conditions was simulated through waterjet impingement analysis, and it was evaluated and compared through enhanced resistance and composite-modified resilience (CMR). An ANN model was developed to predict coating hardness and validated with experimental results. The mechanical and electrochemical properties of each coating were studied and corroborated through SEM, EDAX, and XRD analyses. The methodology in the book is tailored to understand the marine capability of autocatalytic coatings for marine applications. This study underscores the efficacy of ENi-P-nano TiO2 coatings for marine applications, demonstrating their superior mechanical, and electrochemical characteristics.
