DLC Сoating
Employing Diamond-Like Carbon (DLC coating) films fundamentally boosts the resilience and operational effectiveness of machinery parts, curtailing erosion and extending their working lifespan. Our company specializes in delivering premier DLC application solutions tailored for challenging industrial scenarios, guaranteeing exceptional ruggedness, minimized frictional forces, and resilience to chemical degradation.
What is DLC Coating?
DLC coating (or diamond-like carbon coating) is an ultra-hard, wear-resistant carbon-based layer that mimics diamond properties. It is applied using advanced PECVD and PVD methods, ensuring precise thickness and adhesion.
Key properties of diamond-like coatings:
- Extreme surface hardness (up to 90 GPa);
- Low friction coefficient (0.05–0.15);
- High chemical resistance (acids, alkalis, solvents);
- Excellent thermal and humidity stability.
Key benefits of diamond-like carbon coatings
They furnish exceptional resilience, multiplying a component's operational endurance by a factor of 3 to 5 when exposed to rigorous operating conditions. Their superior surface rigidity, paired with a negligible friction factor (0.05), effectively combats deterioration in demanding scenarios, preserving dimensional integrity. These films give full barrier efficacy against corrosive attack from aggressive agents, seawater, and strong acids, rendering them perfect for both marine and industrial deployments.
Concerning optical implementations, DLC preserves upward of 95% of radiant throughput across essential IR spectral regions, avoiding surface clouding or functional decline. Conforming to stringent MIL-SPEC standards, they withstand drastic temperature cycling, elevated moisture levels, and surface erosion, essential for aerospace and defense needs. The synergy of anti-wear properties, chemical inertness, and optical translucence positions DLC treatments ahead of conventional protective methods.
Our specialist group stands ready to adapt tailored approaches to your distinct functional prerequisites and desired performance outcomes.
Main diamond-like carbon applications
DLC coatings are ideal for:
- Infrared optics – Thermal imaging, night vision, surveillance systems.
- Aerospace & defense – Sensors, seekers, and ruggedized optical components.
- Marine & industrial equipment – Protects against humidity and abrasion.
- High-precision optics – Germanium, silicon, and glass substrates.
Our DLC coatings are tested to comply with MIL-STD-810, MIL-F-48-616, MIL-C-48497A, and MIL-C-675C requirements for mechanical and environmental resistance, including thermal shock, humidity, salt fog, sand/dust exposure, and abrasion. This makes them ideal for defense and aerospace-grade infrared optics.
