Electroless Nickel Plating Defense

Why Electroless Nickel Plating is Essential in Defense Manufacturing

A Coating That Goes Beyond Protection The defense and aerospace industries require components made with high precision to tight tolerances. Every component must perform flawlessly, often under extreme conditions. That’s why electroless nickel plating is frequently the coating of choice for mission-critical parts. Often referred to as an “engineering coating,” electroless nickel offers both corrosion protection and precision to plus or minus 0.0001” of thickness. ___________________________________________________________________ Why Defense Engineers Choose Electroless Nickel 1. Uniform Thickness on Complex GeometriesUnlike electrolytic plating, which relies on electrical current, electroless nickel is deposited through a chemical process. This means quality plating can be applied to internal cavities, deep bores, and intricate geometries. Clearly, this meets the needs of critical components in weapons systems and flight hardware. 2. Hardness and Wear ResistanceFormulations that vary the amount of phosphorus in the electroless nickel deposit can increase hardness and improve corrosion resistance. Higher deposit hardness can improve Read more

Understanding the Cost of Metal Coatings: A Practical Guide

When selecting a metal coating for your application, cost is always an important factor. While it might be tempting to choose the least expensive option, it’s critical to understand the trade-offs in durability, performance, and long-term value. Here, we explore how the cost of different coating types compares, particularly focusing on our PEN-TUF® process—electroless nickel with PTFE. Relative Coating Costs There are many effective solutions for environments that require corrosion protection and where the parts are not subject to abrasion. They are relatively low in cost but are often quite effective. Examples include: As performance requirements increase, so does the need for a higher quality coating. For maximum corrosion protection and superior electrical conductivity, precious metal plating is often the best option: Of course, precious metal plating can be costly, especially since gold is currently trading at over $3,000 per troy ounce. PEN-TUF® Pen-Tuf Pentuf® is an electroless nickel plating Read more

Gold Plating

Gold Electroplating is a method of depositing a thin layer of gold onto the surface of another metal. Gold plating finds its uses in jewelry, semiconductor industry. It often requires that the substrate be cleaned and etched before it can be electroplated with gold. Gold plating solution is made by dissolving an appropriate amount of gold salt into water or other solvent. The solution may contain additives such as cyanide ion (CN) to prevent oxidation of the gold during the plating process. Gold Plating Solutions Gold plating solutions are usually classified according to their composition: Cyanide-free solutions: These solutions do not use cyanide ions to stabilize the gold deposits. They typically have higher concentrations of gold than cyanide-containing solutions. However, they tend to be more expensive because of the cost of the gold salts used. Cyanide-based solutions: These electroplating gold solution contain cyanide ions to stabilize gold deposits. In addition, Read more

Plating on Titanium

Plating on titanium parts adds value & functionality for many parts, especially aerospace parts and components. Titanium is an extremely hard metal that can be used in a wide variety of applications. It has excellent corrosion resistance, high strength-to-weight ratio, low density, good thermal conductivity, and high electrical conductivity. Titanium is also highly resistant to abrasion and chemical attack. Titanium is available in three alloys: Ti6Al4V (titanium alloy 6), Ti64 (a special grade of titanium alloy 64) and Ti46Al6V8. The first two are most commonly used, but the third one is more expensive. The process of electroplating or galvanizing titanium involves immersing the part into a bath containing the electrolyte solution. A current is passed through the part, which causes the surface of the part to become coated with a thin layer of metal. This coating may be nickel, zinc, cadmium, tin, chromium, iron, copper, silver or gold. The thickness Read more

Chromate Conversion Coating for Aluminum

Chromate conversion coatings are the most widely used coating for corrosion protection of Aluminum Coatings and Corrosion Protection Chromate conversion coatings are used to passivate metals using an immersion bath process. The chromate conversion coating is a thin film that is applied by immersing the metal in a solution containing hexavalent chromium ions, which react with aluminum oxide on the surface of the metal to form a protective layer. This reaction forms a very stable complex with the chromium ion. The coating can be applied as either a single-stage or two-stage process. In the first stage, the metal is immersed in a dilute acid solution containing hexavalent chrome (Cr(VI)) ions, which reacts with the aluminum oxide to produce CrO3−2Al2O3. During this step, some of the hexavalent chromium is reduced to trivalent chromium (Cr(III)). After rinsing, the coated metal is then dipped into a second solution containing hexavalent and/or trivalent chromium Read more

Bright Tin Plating

What is bright tin plating? Bright tin plating is a type of electroplated coating that uses tin as its main component. This kind of coating has become very popular because of its high corrosion resistance and excellent wear resistance. Bright tin plating is widely applied in various industries such as automotive, aerospace, medical equipment and electronics. Bright tin plating is also known as bright zinc plating or bright nickel plating. The bright tin electroplating process involves using a special solution containing tin ions. After being immersed into the solution, the substrate is then subjected to a current flow. The current causes the tin ions to deposit onto the surface of the substrate. What is the tin electroplating process? The tin plating process is used for coating metals such as aluminum, copper, brass and steel. This process is also known as electroplating. A tin bath is filled with molten tin and Read more

What is Gold Plating?

Gold plating is the process of adding a layer of gold to a metal. This is accomplished both chemically and electrically. By applying a direct electric current to another layer of metal, and applying the gold coating, it creates a chemical bond between the two metals, fusing them together. The layer of a gold coating is very thin, usually in the range of 0.0002 inches. Adding a layer of gold plating to metal has many uses, among them are protection from rust, corrosion or damage. Industrial gold plating companies do large volumes of parts and orders. They do not do gold plating for decorative uses or for single items. Frequently there will be several layers of different metal plating, all used for specific purposes. The Gold Plating Process The first step in gold plating is preparing the surface of the metal. The surface must be very clean in order to Read more
