Phosphate coating and chrome lining—provides a BCG with excellent protection against wear and corrosion, making it a popular choice for those seeking reliability and longevity in their firearms. The phosphate coating provides an initial layer of protection, while the chrome lining offers additional durability and resistance to the stresses of repeated firing.

DLC (Diamond-Like Carbon) coating is a type of thin film coating that mimics the properties of diamond. It’s known for its exceptional hardness, wear resistance, and low friction characteristics. DLC coatings are applied using various techniques and are widely used in industrial, automotive, and consumer applications.

Properties of DLC Coatings

1. Hardness: DLC coatings are extremely hard, often approaching the hardness of natural diamond. This makes them highly resistant to abrasion and wear.
2. Low Friction: The low friction coefficient of DLC coatings reduces friction between surfaces, which can enhance the performance and longevity of moving parts.
3. Corrosion Resistance: DLC coatings provide good resistance to corrosion, protecting the underlying material from degradation due to environmental factors.
4. Chemical Resistance: They are resistant to many chemicals, which makes them suitable for harsh environments.
5. Optical Properties: DLC coatings can be transparent or have a black appearance, and they can be tailored to have various optical properties depending on the application.

How DLC Coating is Applied

DLC coatings are typically deposited using one of the following methods:

1. Chemical Vapor Deposition (CVD): This process involves creating a gas-phase precursor that decomposes on the substrate surface to form the DLC film.
2. Physical Vapor Deposition (PVD): Similar to other PVD techniques, this involves vaporizing a carbon source in a vacuum and allowing it to deposit onto the substrate.
3. Plasma-Enhanced CVD (PECVD): This technique uses plasma to enhance the chemical reaction that deposits the DLC coating.
