Blackening surface treatment is a common metal surface treatment method that can form a black oxide layer on metal products, making them rust proof, aesthetically pleasing, and wear-resistant.

Dalian blackening surface treatment is commonly used for surface treatment of metal products such as stainless steel products, iron products, and copper products. By conducting chemical or heat treatment on the surface of metal products, a uniform and dense oxide layer can be formed on the metal surface, resulting in a black appearance.

Blackening surface treatment has the following characteristics and advantages:

Rust prevention function: The oxide layer formed on the surface of metal products after blackening treatment has good rust prevention performance, which can effectively prevent moisture oxidation and rust on the metal surface.

Aesthetic effect: The surface of the blackened metal products presents a uniform black color, with a unique aesthetic effect, making the metal products more high-end and fashionable.

Wear resistance: The oxide layer formed on the metal surface after blackening treatment has high hardness and good wear resistance, which can effectively extend the service life of metal products.

High temperature resistance: The blackened metal surface has good resistance to high temperatures and can maintain stable surface performance in high-temperature environments.

Blackening surface treatment has been widely used in industries such as home appliances, building decoration, and automotive manufacturing. For example, stainless steel products such as sinks, kitchenware, door handles, etc. often use a blackened surface treatment to give them characteristics such as rust prevention and corrosion resistance. Metal products in architectural decoration, such as iron doors, stair handrails, etc., often use blackened surface treatment to make them aesthetically pleasing and durable.
