Tribometer – PCS – EHD2

Measuring device for ultra-thin lubricating film thickness and friction in an elastohydrodynamic (EHD) contact.

  • Type of motion: sliding and rolling (ball - disc), lubricated
  • Thickness measuring method:
    • white light interferometry (2D thickness distribution, 5 nm - 250 nm)
    • spectrometer (central thickness, 2 nm - 1000 nm)
  • Normal load: 2 N do 50 N
  • Max. contact pressure:
    • 0,67 GPa - 1,95 GPa (tungsten carbide - sapphire)
    • 0,25 GPa - 0,73 GPa (steel - glass)
    • 0,38 GPa - 1,11 GPa (steel - steel)
  • Entrainment velocity: 1 mm/s - 4 m/s
  • Temperature: 20 °C - 150 °C
  • Min. volume of lubricant for the test: 120 mL

+ TINT-developed optical module for measuring advanced contacts (example: DLC)
