Description

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.
