Laboratory: Particle mechanics and adhesion

Measured properties

Adhesion, deformation and breakage properties:

  • Adhesion strength
  • E-Modulus, viscoelastic properties, yield and breakage strength
  • Breakage probability
  • Hardness
  • Friction/attrition/wear particles and surfaces variation of temperatures test in gas or liquid
