Series 600 
For Ferrous & Non-Ferrous Metals

Coating Specifications

Suitable Coating Materials

Series 600 vapor hard thin film coatings can be successfully applied to most metals; however, some coatings within this product platform require high deposition temperatures to achieve proper adhesion to the base metal. Certain Series 600 coatings have processing temperatures that can reach up to 1,000°C (1,832 °F). Consequently, tool steels, high speed steels, and carbides are preferred. Material which are not suitable include copper, leaded steels, cast iron, oil-hardened steels and in some instances aluminum as well.

Coating Thickness

Our vapor hard thin film coatings are applied in a variety of methods which are contingent on the specific coating/material system being deposited. Methods include high temperature vacuum evaporation, plasma sputter bombardment as well as chemical vapor deposition. Such application methods allow us to attain ultra thin builds while still holding extremely tight tolerances. Surface growths within our 600 Series product family may be as thin as 2µm per surface (0.00007874 inch) or as thick as 12µm per surface (0.000472441 inch), depending on the coating system being implemented.

Surface Finish (RMS)

Series 600 coatings are highly conformal and uniform in nature. Given that they possess extremely thin films, these coatings will replicate your parts surface geometries and closely mirror their existing RMS surface values. Consequently, any existing surface imperfection in your base metal will remain post processing.


Our 600 Series coatings will dramatically increase the surface hardness of your tooling or component. Final post coating micro hardness values vary based on coating selection and range from 2,600 HV up to 3,400 HV.

Wear & Abrasion Resistance

Series 600 coatings are engineered to provide maximum wear and abrasion resistance. Their combination of increased hardness and low friction surface properties greatly reduce wear associated with galling, high impact, seizing, and fretting.

Low Coefficient of Friction

Series 600 coated surfaces are smooth and provide an extremely low coefficient of friction. Values normally range from 0.06 to 0.35, which are coating and application dependent.

Chemical & Corrosion Resistance

Many of our 600 Series coating systems possess good chemical corrosion resistivity, however, some are better suited than others and will be dictated by your application’s maximum operating temperature as well as what caustic or acidic agents are present. To ensure we specify the most appropriate 600 Series solution for your use environment, MSDS sheets may be requested by our technical consultants for review. Once a spec has been determined, we recommend that you evaluate the selected Endura® 600 Series coating against the corrosive elements of your application. Sample coupons are available upon request to test the compatibility of our coatings in your use environment.

Operating Temperature Range

Coatings will withstand severe temperature extremes without loss of physical properties. Coatings are available to operate from cryogenic up to approximately 1,742°F (950°C), depending on the specific coating being applied.

Critical Processing Factors

Surfaces That Are Best For Coating

Finely ground surfaces, free of grinding burns, are best for achieving optimum coating adhesion and performance.

Surface Condition before Coating

The surface preparation and treatment prior to coating is critical to achieve proper adhesion and a defect free surface. The component must be free of all contaminants such as rust, paint, wax, polishing compounds, oil, die, rust preventative, and even dust or fingerprints. Endura® will clean your components as part of our operation, but providing clean parts and advising Endura® of previously applied materials is extremely helpful to ensure the proper pre-treatment.

Heat Treatment before Coating

Please advise Endura® of any heat treating or surface hardening, so we may adjust our coating pre-treatments to accommodate for these processes. Please also advise if your component has been salt bath heat treated as additional special cleaning processes may be required.

Coating and Masking

The components must be fixtured or held for the coating process; therefore, an agreeable area such as a through or threaded hole or surface that may contain a small coating void is required. Masking of surfaces may be possible pending surface configurations and if desired should be discussed with your Endura® contact so masking definition and plans can be created.
