||Ethanol fuel corroding alloy and zinc die cast components quickly blocking narrow fuel channels
||5-9 mm ENi coating
||Excellent corrosion resistance resulted in elimination of corrosion problems
|Hard-chrome plated differential pinion shafts
||Concerns about heat treating parts – making them brittle. Also galling of hard-chrome surface.
||25 mm high phosphorous electroless nickel
||Lubricity of the coating actually increased (no galling)
performance of the parts. The hardness of the surface eliminated the
need to heat treat the shafts
|Steel fuel and brake line tubes
||Zinc plated tubes corroding internally whilst still in stock
||8-10 mm high phosphorous electroless nickel
||Electroless nickel solved corrosion problem as coating was able to
reach internal surfaces however cost to plate Eni far higher than Zn.
||Currently flash hard chrome to save re-finishing product but not really thick enough
||8-12 mm high phosphorous Eni
||Surface condition superior and outlasts hard-chrome flash.
