A Review of Wear-Resistant Coatings for Steel Substrates: Applications and Challenges

This study reviews the current research status and future trends in the field of abrasive-resistant coating preparation, focusing on steel coating technology. The types of materials, preparation methods, and application status of the abrasive-resistant coatings are described in detail. First, the necessity for an abrasive-resistant coating is analyzed from the perspective of steel applications. Second, abrasive-resistant coating materials of different substrates, including metal-, ceramic-, composite-, and polymer-based materials, are systematically expounded, and the composition, property characteristics, and applications of the materials are systematically discussed. Next, the principles, advantages, and disadvantages of different preparation techniques are analyzed and compared, and the relevant research results are summarized, showing the urgent demand and application prospects of abrasive-resistant coatings. Finally, the performance of the coating is presented, and the development trend of abrasive-resistant coatings on steel surfaces is discussed, providing theoretical support and new ideas for innovation in this field.
