LIQUID TRIBOLOGY INTRO

Liquid Tribology Process:
Nanovea Tribometer provides the liquid/lubricant linear and rotative cup modules to carry out wear and friction experiments in liquids or lubricants. Different liquid solutions can be used to simulate the wear process for realistic applications. The wear and friction of materials in liquids or lubricants is critical for various industrial applications. For example, the biomaterials for biological replacements such as joints, stents and dental roots, require excellent long term resistance and adequate strength in a liquid environment. The parts in the motor engines should be protected by proper lubrication to reduce wear and friction and to extend lifespan. During the wear test, the evolution of coefficient of friction provides insight in different stages of the wear development. Combining with the precise control of speed and continuous change of speed, a continual Stribeck Curve for the test lubricant can be measured. A liquid heating coil is available to heat the liquid in the cups up to 150°C. An accessory to the cup is the drop by drop lubrication option which allows lubrication test even at very fast rotation speed of 5000rpm.
