Let us examine both processes.
Black oxide coating, also known as blackening, is ideal for coating ferrous materials, stainless steel, copper-based alloys, copper, zinc, and silver solder. It impacts metals with mild corrosion resistance, minimizes light reflection, and improves aesthetics. Unlike black anodizing, black oxide coats materials in a chemical conversion. There are three methods of black oxide coating depending on the temperature used; hot, mid-temperature, and cold.
On the other hand, black anodizing is an electrochemical process that helps make aluminum more beautiful and durable. This process makes the surface of metals resistant to weather elements for a long time. For best results, it is best to ensure all surfaces involved in anodizing are clean, free of contaminants, and dry.
