Oerlikon Metco’s nickel-chromium based superalloy powders produce dense, self-bonding, single-step coatings that are oxidation and corrosion resistant at elevated temperatures.
Their compositions are similar to Inconels, thus the coatings have excellent high temperature oxidation and corrosion resistance for restoration and repair of superalloy components. They are also recommended as overlay coatings to protect less noble materials from oxidation.
The coatings exhibit high tensile bond strength and thickness limits exceeding 1.5 - 2.5 mm (0.06 - 0.1 in) when sprayed with liquid-fuel or gas-fuel HVOF guns, depending on part geometry. The coatings can be machined, milled, drilled and tapped without chipping and excellent edge retention.

Store in the original container in a dry location; Tumble contents gently prior to use to prevent segregation; Open containers should be stored in a drying oven to prevent moisture pickup; Remove desiccant prior to use, if applicable.
Designed for restoration of worn or mismatched components of Inconel 625 or similar substrates. Diamalloy 1005 and Diamalloy 1005A are sized for HVOF. For better deposition efficiency using liquid-fuel HVOF, Diamalloy 1005A is recommended.
