Introduction:

BODA 25NiCr-Cr3C2 series of products are spheroidal, agglomerated and sintered powders for thermal spray that contain 75 %chromium carbide as a hard, wear-resistant phase that has a minimal tendency for decomposition during the thermal spray process. A nickel-chromium (80 % / 20 %) matrix functions as a binder for the carbides, and is also responsible for the excellent corrosion and oxidation resistance of these coatings.When compared to coating materials containing tungsten carbide, coating materials that contain chromium carbide are often used because they can withstand higher service temperatures up to 870 °C (1600 °F).

Coatings of BODA 25NiCr-Cr3C2 series materials protect against abrasion, various forms of erosion and tribo-corrosion at elevated temperatures. They are well-known as an alternative to hard chromium plating with better corrosion resistance in sodium chloride, acidic and alkaline environments. Environments with HCl as a corrosive medium should be avoided.

HVOF coatings of these materials are dense, show good bond strength and are more homogeneous than coatings applied using atmospheric plasma spray or combustion powder flame sprayed coatings.

Typical Uses and Applications:

* Hydraulic cylinders and piston rods

* Valve stems

* Boiler coatings

* Chemical processing tooling

* Turbine components

* Sieves and cones

* Ship engine valve spindles

* Furnace rolls in metal production
