A detailed explanation of the process of water plating black titanium on Stainless steel
Stainless steel is widely used in various fields due to its corrosion resistance and high strength. Moreover, by adding color and texture to stainless steel through surface treatment processes, it has shone brightly in decoration, construction and industrial fields. Among them, water plating of black titanium is a highly favored surface treatment technology that endows stainless steel with an elegant black metallic luster. Today, let's take a detailed look at the process of water plating black titanium on stainless steel and the relevant precautions.

What is water-plated black titanium?
Water plating of black titanium is a process that uses electrochemical principles to form a black titanium compound film layer on the surface of stainless steel. This film layer can not only enhance the corrosion resistance and wear resistance of stainless steel, but also endow the surface with a unique decorative effect. Compared with traditional spraying or electroplating processes, water plating of black titanium has the advantages of being environmentally friendly, having strong adhesion and uniform color.

The main steps of water plating black titanium
1. Workpiece pretreatment
Before water plating of black titanium, stainless steel workpieces must undergo adequate pretreatment to ensure that the surface is clean, free of oxides and oil stains. Preprocessing usually includes the following several steps:
- Degreasing: Use alkaline cleaning agents or ultrasonic cleaning equipment to remove grease from the surface of the workpiece.
- Pickling: Use dilute nitric acid or other acidic solutions to remove the surface oxide layer and rust.
- Water washing: Thoroughly rinse the workpiece with pure water to avoid residual chemical substances.
2. Activation treatment
In order to enhance the adhesion of the coating, it is necessary to activate the surface of the workpiece. Usually, the workpiece is soaked in an acidic solution for a short time to make the surface smoother and remove trace residues.
3. Preparation of black titanium plating solution
Water plating of black titanium requires the use of a specific plating solution, which is usually composed of titanium ions, complexing agents, additives and other components. The ratio and temperature of the plating solution have a significant impact on the final effect. Therefore, it is necessary to strictly follow the formula for mixing and maintain the stability of the solution.
4. Electroplating process
The stainless steel workpieces that have undergone pretreatment and activation are immersed in the black titanium plating solution, and electroplating begins after being electrified. At this point, titanium ions are deposited on the surface of the workpiece under the action of an electric field, gradually forming a uniform black film layer. Current density, time and temperature are important parameters that determine the quality of the film layer and need to be adjusted according to the material and requirements of the workpiece.
5. Post-processing
After electroplating is completed, the workpiece needs to undergo subsequent treatment to enhance the performance of the film layer and the appearance effect:
- Cleaning: Rinse off the residual plating solution on the surface with pure water.
- Drying: Dry the workpiece to prevent water stains from affecting the surface gloss.
- Sealing: In some cases, the film layer can be sealed to enhance its corrosion resistance.
6. Quality Inspection
The final step is to conduct a quality inspection on the completed workpiece to ensure that the film layer is uniform, defect-free, and meets the expected decorative effect and performance requirements.

The advantages of water plating of black titanium
1. High-end and grand appearance: The black titanium film layer presents a deep and uniform black metallic luster, which is highly decorative.
2. Strong corrosion resistance: The black titanium film layer can effectively protect the stainless steel substrate and extend its service life.
3. Good environmental friendliness: Compared with traditional electroplating processes, water plating of black titanium is more environmentally friendly and causes less pollution to the environment.
4. Strong adhesion: The film layer is closely bonded to the substrate and is not easy to peel off or be scratched.

Precautions
1. Strictly control process parameters: Parameters such as temperature, current density, and time directly affect the quality of the coating and need to be precisely controlled.
2. Keep the working environment clean: Impurities may cause coating defects, so the working environment and equipment need to be cleaned regularly.
3. Select high-quality raw materials: The composition of the plating solution and the quality of the stainless steel substrate are crucial to the final effect.
4. Properly handle waste liquid: Although water plating of black titanium is relatively environmentally friendly, it is still necessary to properly handle the waste liquid to avoid polluting the environment.

Application field
Water-plated black titanium is widely used in high-end decoration, household goods, electronic product casings, automotive parts and other fields, for example:
Columns and guardrails in architectural decoration;
High-end kitchenware and tableware;
Consumer electronic products such as watches and mobile phone cases.
