Surface treatment

Favorable running-in and fatigue strength properties, as well as corrosion protection, are obtained using specialised surface treatment of the precision forged parts.

  • The running-in properties of precision forged differential bevel gears is improved by specialised coatings, including manganese phosphatisation. In addition, contact and rolling wear is reduced.
  • Mechanical surface strengthening processes, including shot peening, mean that the favorable strength properties of precision forged components can be further increased.
  • Components are corrosion protection according to the customer's requirements.
