CVD coated stands for Chemical Vapor Deposition coated. It refers to a surface treatment process where thin films are applied to various materials using a method called Chemical Vapor Deposition. This process involves chemical reactions in a controlled environment, typically a vacuum chamber, where a reactive gas mixture is introduced and heated to a reaction temperature. The gas reacts or breaks down to deposit a thin film onto the substrate's surface. This method is widely used in industries to enhance material properties such as durability, corrosion resistance, and thermal stability.
Key Points Explained:
