Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add corrosion protection, for appearance, and to minimize light reflection. Benefits.
Applying the black oxide coating on metal parts occurs at three temperatures, determining the coat. At a hot temperature (141°C) and mild temperatures (90 – 120°C), there is a deposit of a magnetite coat (Fe2O3). At a cold temperature (20 °C – 30 °C), there is a deposit of a copper selenium coat (Cu2Se). After applying the black oxide ...
Bronson Plating is a leader in black oxide coating, a conversion coating for ferrous materials. Black oxide is a great choice for minimal build-up, the ability to add mild corrosion resistance, and for its appearance.
10 paź 2024 · Step 1: The metal part is dipped into a hot chemical solution. The chemicals in the solution react with the metal's surface, turning it black by creating a thin layer of iron oxide. Step 2: The layer of rust that forms is only about 0.5 to 2.5 millionths of a meter thick. But it protects the metal underneath because it bonds strongly to the ...
7 lis 2023 · The black oxide coating or blackening process is a chemical reaction in which the outer surface of a metal reacts to chemical solutions and therefore undergoes transformation. The process is divided into three main types: Hot black oxide process. Mid-temperature black oxide process. Cold black oxide process.
