Hard Coat Anodization at ECO Finishing

ECO Finishing provides Hard Coat Anodization, a Type III process that can be controlled to very close thickness tolerances where maximum serviceability or special properties are required, such as on hydraulic cylinders, wear surfaces, actuating cams, etc. Our Hard Coat Anodization meets MIL-A- 8625F specifications and provides a very hard ceramic like coating that can also be used as an electrical insulation coating. “Flash” hard anodization may be used instead of conventional anodization for corrosion resistance and may be more economical in conjunction with other hard anodized areas.

The color will vary from light tan to black depending on alloys and thickness. The finish can be dyed in darker colors depending on the thickness. This coating penetrates as much as it builds up on the surface, and the thickness includes both the buildup and the penetration of the layer.

With over 60,000 sq ft of clean, well lit space, ECO Finishing has a streamlined plating process that complies with all EPA regulations regarding safety and waste treatment.

Quality is at the heart of ECO Finishing. Each job is carefully monitored from its arrival through the entire plating process. Inspection of plated parts is enhanced by more than 100 foot candles of light throughout the entire plant. Electroplating thickness measurements are verified with X-ray fluorescence and our quality system conforms to military specifications as outlined in MIL-Q-45208. ECO uses Statistical Process Control (SPC) to assure that our product meets exacting industry standards.
