2. Overview of the Hard Chromium Plating Process
Hard chromium plating is the process of applying a chromium layer onto a metal substrate (often steel, aluminum, or alloys) through electroplating to enhance the material’s wear resistance, hardness, corrosion resistance, and oxidation protection. The chromium layer typically ranges from 0.025 mm to 0.250 mm in thickness, but it can be thicker depending on specific technical requirements.
Hard chrome plating not only provides superior wear protection but also improves the dimensional accuracy and surface finish of parts. This process is commonly used in machinery components that require high durability, hardness, and stability under extreme operating conditions.
SAI GON HYDRAULIC MACHINERY AND EQUIPMENT CO., LTD is known for its ability to plate large-scale components, with the capability to plate items up to 3 meters in diameter and 15 meters in length. This makes the company a leader in providing high-quality hard chrome plating solutions for both industrial and specialized applications in Vietnam.

3.2. Electroplating Process
During electroplating, a direct current (DC) is applied between the anode and the cathode. Chromium ions from the solution move toward the cathode (the material to be plated) and are reduced to metallic chromium, forming a coating on the material surface. Simultaneously, the solution’s ions are balanced and regenerated through oxidation at the anode.
- Current Density: The current density is a key factor in controlling the plating process. Too high a current density may result in an uneven coating, while too low a current density may not produce a sufficiently thick coating to meet the required hardness and durability. Proper control of current density ensures uniform, high-quality plating.
- Plating Rate: The plating rate (the speed at which chromium is deposited) depends on factors such as current density, solution composition, temperature, and additives.
4. Factors Affecting the Hard Chromium Plating Process
Several factors affect the quality of the chrome coating. The following factors are crucial for achieving optimal results:
4.1. Current Density
Current density plays a crucial role in the chromium plating process. Too high a current density can lead to uneven coatings, causing defects such as cracks or poor adhesion. On the other hand, too low a current density may result in a thin, insufficient coating. By controlling current density, it is possible to achieve uniform and durable coatings.
4.2. Composition of the Plating Solution
The plating solution is primarily composed of chromic acid (H₂CrO₄), but additives such as sulfuric acid (H₂SO₄) and other chemicals can be added to enhance the coating’s finish, adhesion, and wear resistance. The solution’s composition impacts the plating rate and the overall performance of the coating.
4.3. Solution Temperature
The temperature of the plating solution significantly affects the plating process. Excessive heat can lead to the decomposition of the solution and negatively impact the coating’s quality, while too low a temperature may reduce the plating rate and cause the coating to fail to achieve the desired hardness. Typically, the plating solution temperature ranges from 45°C to 60°C.
4.4. Surface Quality of the Material
The surface of the material to be plated must be thoroughly cleaned to remove contaminants like oil, grease, dirt, rust, or metal oxides. Surface cleaning ensures better adhesion and improves the longevity of the chromium coating. Common cleaning methods include grinding, sandblasting, or treatment with alkaline solutions.

5. Types of Hard Chromium Plating
Hard chromium plating can be divided into two main types, depending on the application:
5.1. Static Hard Chromium Plating
In static plating, the material to be plated is immersed in a plating bath without movement. This method is commonly used for plating flat surfaces or simpler parts. However, plating more complex parts may be challenging using this method.
5.2. Dynamic Hard Chromium Plating
Dynamic plating involves continuously moving the components in the plating solution. This technique ensures uniform coatings for parts with complex shapes or large components. SAI GON HYDRAULIC MACHINERY AND EQUIPMENT CO., LTD utilizes dynamic plating to achieve high-quality chrome coatings for large and intricate industrial components.

6. Standards and Quality Control in Hard Chromium Plating
To ensure the quality of the hard chromium coating, the process must adhere to strict international standards. Some of the key standards include:
- AMS 2460: A standard from the Society of Automotive Engineers (SAE) that specifies requirements for coating thickness, hardness, wear resistance, and adhesion for aerospace applications.
- ISO 1456:2017: An international standard that provides guidelines for metal plating processes, including hard chromium plating.
- QQ-C-320: A U.S. military standard specifying requirements for hard chromium plating, particularly for applications that demand high durability and wear resistance.
SAI GON HYDRAULIC MACHINERY AND EQUIPMENT CO., LTD ensures compliance with these standards to provide high-quality and reliable chromium coatings for a wide range of industrial applications.
