Can You Cerakote a Nitrided Action? The Definitive Guide
The question of whether you can Cerakote a nitrided action is a common one among firearm enthusiasts. The short answer is: yes, you can, but it requires careful consideration and preparation. This guide will delve into the intricacies of Cerakoting nitrided actions, outlining the benefits, drawbacks, and the best practices to ensure a successful and durable finish.
Understanding Nitriding and Cerakote
Before we dive into the compatibility, let's briefly review each process:
-
Nitriding: This is a heat treatment process that diffuses nitrogen into the surface of the metal, creating a hard, wear-resistant, and corrosion-resistant layer. It's known for its exceptional durability and is often applied to firearm components like bolt carriers, barrels, and actions. The nitrided surface is typically a dark gray or black.
-
Cerakote: This is a ceramic-based coating that offers superior protection against abrasion, corrosion, and chemical damage. It's available in a vast array of colors and finishes, allowing for customization and aesthetic enhancement. Cerakote is applied as a liquid and cured using heat.
The Compatibility Question: Can Cerakote Adhere to Nitriding?
The good news is that Cerakote can successfully adhere to a properly prepared nitrided surface. However, the nitriding process creates a very hard, non-porous surface, meaning proper surface preparation is crucial for optimal adhesion. Poor preparation can lead to peeling, chipping, or other coating failures.
Preparing Your Nitrided Action for Cerakote
This is the most critical step. Failing to adequately prepare the surface will compromise the entire process. Here's a detailed breakdown:
-
Cleaning: Thoroughly clean the nitrided action using a degreaser specifically designed for firearm parts. Remove any oil, grease, dirt, or other contaminants. Pay close attention to crevices and hard-to-reach areas. Multiple cleaning cycles may be necessary.
-
Abrasive Blasting (Optional but Recommended): While not strictly necessary, abrasive blasting with very fine media (such as glass beads or aluminum oxide) can create a slightly roughened surface, providing better mechanical adhesion for the Cerakote. This is especially crucial if the nitrided surface is extremely smooth. Caution: Excessive blasting can remove the nitrided layer, defeating the purpose. Professional blasting is highly recommended if you're unsure.
-
Degreasing (Again!): After blasting (if done), thoroughly degrease the action again to remove any blasting media residue.
Applying Cerakote to a Nitrided Action
Once the surface is meticulously prepared, the Cerakote application process follows standard procedures:
-
Preheating: Some Cerakote formulations may benefit from preheating the action to the manufacturer's recommended temperature.
-
Application: Apply thin, even coats of Cerakote using an appropriate spray gun or other application method. Multiple thin coats are better than one thick coat.
-
Curing: Carefully cure the Cerakote according to the manufacturer's instructions. This typically involves baking the coated action in an oven at a specific temperature for a set amount of time.
Potential Challenges and Considerations
-
Adhesion Issues: As mentioned, improper preparation is the biggest risk. If the Cerakote doesn't adhere properly, it's likely due to insufficient cleaning or surface preparation.
-
Color Changes: The dark color of the nitrided surface might affect the final color of the Cerakote. A base coat might be necessary to achieve the desired shade.
-
Professional Application: If you lack experience with Cerakoting, it's best to seek the services of a professional. They have the expertise, equipment, and environment to ensure a flawless finish.
Conclusion
Cerakoting a nitrided action is achievable, but requires meticulous preparation. By carefully following the steps outlined above and prioritizing surface cleanliness, you can achieve a durable and aesthetically pleasing finish. Remember to always consult the Cerakote manufacturer's instructions and consider professional application if you are unsure. The result will be a firearm with enhanced protection and a customized look.
