Advanced Duralar Vacuum Coating Equipment – To Give You Total Control
Putting Duralar vacuum coating equipment into your own production lines can save considerable time and expense in your production cycles and give you maximum control of your coating process — all this in addition to gaining all the performance benefits of Duralar coating technology.
Duralar Technologies currently offers a range of deposition systems for sale to the markets we serve. These include both Duralar and InnerArmor brand systems, for external and for internal coating applications…
Duralar Centurion – external coating system
The Duralar Centurion deposition machine is a versatile hybrid design for advanced coatings with both PVD and PECVD processes. This system is configured for productive, cost-efficient industrial batch coating and is designed to provide high-volume production for medium/small size pieces, or lower-volume high-mix pieces.
Parts to be coated have independent bias control and are rotated in a planetary motion for optimized uniformity. The chamber is fully equipped with heaters, turbo pumps, a dry roughing pump, and mass flow controllers including a delivery system for the liquid molecular diamond precursor. All hardware is controlled through an advanced PLC (programmable logic controller) and an intuitive HMI (human machine interface). Processes are automated through recipes and easily transferred from the Duralar R&D center to tools at customer sites.
Duralar Maximus – internal coating system
The Maximus™ system is designed for coating the internal surfaces of parts. It accommodates ten identical component setups of high aspect ratio parts. This chamber-based PECVD system utilizes pulsed DC and ten separate gas feeds and electrical splitters for uniformity across the ten substrates. The system is equipped with a dry pump and booster, heaters, mass flow controllers and valves controlled by an advanced PLC and intuitive HMI with recipe control and remote data logging.
Duralar CS-10 – internal coating system
The Duralar CS-10 coating system incorporates InnerArmor coating technology originally developed by our Sub-One subsidiary for specialized internal-surface coating. The CS-10 utilizes patented hollow-cathode ion immersion processing, and its flexible design enables it to apply surface enhancements that can be tailored to a range of applications. InnerArmor coatings are applied to internal surfaces via plasma-enhanced chemical vapor deposition which enables the coating of complex interior geometries without being limited to line-of-sight.
The Duralar CS-10 is equipped with vacuum heads with KF100 flanges for easy connections to the parts to be coated — enabling each part to act as a chamber. The heads are designed to provide gas delivery and evacuation as well as anode housing. The CS-10 is equipped with a high-power DC power supply and asymmetric bipolar DC pulsing system, eight mass flow controllers and associated valves as well as heaters, pressure gauges, and dry pump with booster controlled by a PLC and intuitive HMI with recipe control and remote data logging.
Duralar CS-50 – internal-and-external coating system
This Duralar system is similar to the CS-10 except that the CS-50 features a tubular chamber with clamshell design and top access allowing metal parts to be placed inside for coating. The CS-50 uses Duralar’s patented DualArmor™ technology which enables simultaneous coating of both the internal and external surfaces of parts. The hollow-cathode PECVD process bathes parts in an extremely intense plasma — roughly 1000 times greater than a standard CVD plasma — which enables coating at unprecedented high rates. Also, since all deposition occurs within the dense plasma, it does not have the line-of-sight limitations of spray-type coatings. All part surfaces — interior, exterior and complex 3D shapes — are coated with high uniformity, eliminating the need for post-processing rework.
The CS-50 chamber size is 60 inches long by 10 inches in diameter, and coatings can be more than 50µm in thickness. This system is designed for high-rate, high-quality deposition for production environments. Previous processes could take more than 8 hours to deposit 1µm of conventional DLC — but the CS-50 can deposit high-quality DLC many times faster, typically 15-20µm per hour. And it is capable of considerably higher rates, as well.
