Characteristics of the vibrocryotribometer (VCTM bench)

Contact geometry : 

• Sphere / plane (adjustable sphere radius)

• Plane / plane

Kinematics :

• alternative : amplitude from 1 to 1000 micro-m, frequency from 1 to 600Hz

Loading :

• Constant normal force : 30 to 300 N
• Measured tangential force : 1 to 300 N

Ambient :

• T° from -196°C to +250°C
• LN2, Air, water, oil

Applications : contact fatigue by small deflections (fretting-fatigue) and wear (fretting-wear). In this test method, the specimens are not volumetrically stressed.
