New Surface Treatment on ZRP Crankshafts

In our continuing quest for improvement, we are pleased to announce that, all the new ZRP Billet crankshafts will feature ION (Plasma) Nitriding instead of our traditional Gas Nitriding.

The benefits of this new treatment are many:

• Least affects the surface finish of the product. has a higher surface hardness and maintains your material’s core properties due to the lower processing temperatures associated with plasma nitriding (900 – 950 Fahrenheit). Traditional nitriding operates at 975 -1075 Fahrenheit and can change the core properties of your material.
• Imparts a hard wear resistant surface without brittleness, galling, or spalling. This eliminates costly cleaning or grinding to remove the brittle white layer associated with traditional nitriding.
• A uniform glow discharge that envelops the entire surface achieves a consistent hardness and case depth. This is especially noticeable on complex geometries where gas nitriding case depths can be non-uniform.
• Last but not least, Plasma nitriding is environmentally friendly. It uses non-toxic precisely controlled gas mixtures.
