Our nickel based coating is engineered specifically for increased plunger longevity. The coating has a much
larger diffusion zone than the standard industry coating which allows for much stronger coating adhesion.

 

This increased adhesion creates an extremely hard and wear resistant coating. The micro hardess of the
coating is 820 HV and the macro hardess is 91.7 15N. The measured porosity of the coating is around 0.36%,
which also makes the coating extremely corrosion resistant.

 

Other benefits of our plungers include:

• Strong, tenacious metallurgical bond

• Low porosity

• Consistent, robotic application process

• Large Diffusion Zone
