Features: This book is a fundamental course for the applied chemistry major in universities. It combines basic applied chemistry knowledge with metal corrosion theory to provide scientific training in metal protection. The book includes 31 experiments, divided into two parts: Part I (Experiments 1-15) primarily focuses on experiments related to the principles of metal corrosion, including weight loss methods for measuring metal corrosion rates, determination of various polarization curves, etc.; Part II (Experiments 16-31) primarily focuses on basic experiments in metal protection, including electroplating, chemical plating, anodic oxidation, metal phosphating, etc. The entire experimental content emphasizes metal protection technology, with most experiments demonstrating strong practical applicability. Through experimental activities, students can achieve the goal of integrating theory with practice, while also fostering creative learning, improving experimental skills, and enhancing problem-solving abilities. This book can serve as a textbook for universities and colleges offering applied chemistry, materials science, and other related majors in "Materials Protection Experiments." It can also be used as a reference for universities and colleges in chemical engineering, mechanical engineering, metallurgy, and related fields when teaching "Materials Protection Experiments." Additionally, it is available for reference by relevant engineering technicians.
