Have you ever wondered how Shengen ensures its metal parts’ durability and long-term use? It all starts with the finishing process. As Technical Director, I have seen raw materials transformed into products of high quality that last. Nickel plating is a technique that we use frequently.
Nickel plating stainless steel is the process of coating the surface with nickel. This layer improves the metal’s corrosion resistance, wear resistance, and surface hardness. The process generally begins with the stainless steel item immersed in a nickel-plating solution containing nickel ions. Then, we use an electric current to help form a nickel coating on the surface.
Stay tuned as we reveal the secrets of nickel plating stainless steel. You’ll know everything from the how to the why by the end.
What is Nickel and Stainless Steel Plating?
What is Stainless Steel?
The main components of stainless steel are iron, carbon, and at least 10.5% chrome. This composition gives stainless steel its remarkable corrosion resistance. The chromium forms a layer of chromium dioxide on the surface that protects the steel underneath from corrosion. Depending on the application, nickel, molybdenum, titanium, and copper can be added to improve its strength and formability.
There are different types of stainless steel, which can be classified based on the crystalline structure. These include austenitic, ferritic, martensitic, duplex, and precipitation-hardening stainless steels. Austenitic stainless is known for its formability and corrosion resistance.
Nickel plating stainless steel is a process of nickel plating.
Nickel plating involves depositing a thin nickel layer onto a metal surface. We use two primary nickel plating methods at Shengen: electroplating and electroless plating. Electroplating uses an electric current to bond nickel ions to the substrate. Electroless plating, on the other hand, relies on chemical reactions to achieve the desired effect. Each method is advantageous and chosen according to the particular project’s requirements.
Nickel plating stainless steel has many benefits. Nickel plating increases corrosion resistance and is ideal for harsh environments. The nickel plating increases the surface hardness of metals, which reduces wear and extends their life. Nickel plating also gives the metal a shiny finish, enhancing the aesthetic appeal. Nickel-plated stainless is valuable for industries requiring functionality and aesthetics, like the aerospace and automotive sectors.
Pre-Plating Prepared
We must prepare the stainless steel meticulously before beginning the nickel plating stainless steel process. Here’s what we do to prepare the metal for plating.
Cleaning and Surface Preparation
First Step: Degreasing
Degreasing is the first step in surface preparation. We remove all contaminants, oils, and grease from the metal surface. We usually achieve this by ultrasonic cleaning or by applying organic solvents. The surface must be immaculate and free of all substances that may interfere with the plating procedure.
Mechanical cleaning: Ensure a smooth surface
After degreasing, we use mechanical cleaning methods like abrasive sandblasting or polishing. This step is crucial for removing oxide layers and smoothing the surface. We can improve the adhesion between the nickel and stainless steel substrate by creating a smooth surface.
Chemical Cleaning: The Final Touch
The final stage of surface preparation is chemical cleaning. This may include a series of acid dips to remove surface contaminants. This ensures the metal is in a condition allowing optimal nickel deposition.
Activation of Strike Layers
Nickel Plating: The role of activation
The activation of stainless steel is essential. This metal is known for its passive coating that resists corrosion. To ensure the adequate adhesion of nickel, we must disturb this layer. We use mild acid solutions to lightly etch the surface. This removes and activates the passive surface, preparing it for nickel plating.
Applying the Strike layer: A crucial step for adhesion
Next, you must apply a strike-layer. We deposit the nickel using either electroplating or electroless plating methods. The strike layer is a primer that improves the adhesion between the nickel layers. This is a crucial step to ensure the quality and durability of the nickel-plated steel.
Nickel plating methods
We use two plating techniques to achieve the highest quality nickel-plated stainless-steel components in Shengen: electroplating and electroless plating. The two plating methods have unique applications and advantages, allowing us to meet the needs of various clients.
Electroplating
The Electroplating Process – Explained
The electroplating process involves the passage of an electric current in a solution that contains nickel ions. The cathode is stainless steel, while the anode is nickel. When we apply electricity, the nickel ions adhere to the surface of the cathode, which we intend to plate. We can control the thickness of the nickel coating by adjusting the intensity and duration of the electric current.
Equipment and Solutions for Electroplating
Electroplating equipment includes a power source, a plating tank, electrodes, and various chemicals to make the plating solution. The plating solution must be composed of nickel sulfate and nickel chloride, as well as boric acid and other additives to improve the plating. We meticulously maintain Shengen’s equipment and solutions to achieve consistent, high-quality outcomes.
Electroless Plating
Understanding Electroless Nickel Plating
As the name implies, electroless plating does not require an external electric current. It uses a chemical process to deposit the nickel onto the substrate. As we immerse the part into the plating solution, the nickel ions are reduced and bonded to the part’s surface. This allows uniform coating on internal surfaces and complex shapes.
Benefits of Electroless vs. Electroplating
Electroless plating has several advantages over electroplating. It is possible to obtain a uniform nickel layer regardless of part geometry. This ensures even intricate parts with blind holes and recesses receive a uniform coating. This is crucial for parts used in high-precision applications. Electroless plating also results in a more corrosion-resistant layer, making it perfect for parts exposed to harsh environments.
Aftercare and Maintenance
Shengen understands that after nickel plating, the journey to ensuring longevity and maintaining the quality of plated components continues. After-plating treatments and proper maintenance are crucial to ensure that nickel-plated stainless-steel parts continue to meet or exceed our client’s expectations.
After-Plating Treatments
Stress Relieving: Ensuring Durability
Stress relieving is one of our most critical post-plating techniques. The plated parts are heated to a specific temperature and then allowed to cool slowly. This treatment can reduce internal stresses introduced during the plating procedure, increasing the durability. This is especially important for components used in extreme conditions or under rigorous use.
Bright Dipping: Enhancing Aesthetics
Bright dipping is the perfect solution for parts equally important in aesthetics and functionality. This chemical polishes and enhances the shine of the nickel surface. Bright dipping is popular with visible components, as the appearance of the component can significantly impact the user’s perception of the product’s quality.
Maintenance Tips
Regular Cleaning Guidelines
Regular cleaning is necessary to maintain the quality of nickel-plated parts and prolong their life. We recommend gently cleaning the surface with a soft rag and mild detergent. Avoid abrasive products or harsh chemicals, which can damage the nickel finish. Rinsing the surface with clean water after cleaning and then drying it with a soft towel will help to preserve the finish.
How to prevent and treat wear and tear
Nickel plating is durable but can wear out, especially if exposed to harsh environments or used frequently. Avoiding this by handling the parts with care and avoiding corrosive materials is essential. It’s best to consult an expert if you notice any wear or corrosion. Re-plating is sometimes necessary to restore a component’s protective coating and appearance.
