COVID-19: In these troubled times, NANOVEA devotes necessary resources to maintain all of the essential services you count on. Stay safe!


Irvine, Calif., Oct 24, 2013 – Nanovea demonstrates for the first time the ability to measure a continuous Stribeck Curve. Using the Nanovea Tribometer advanced speed control, from 2000 to 0.01 rpm, within 10 minutes software monitoring provides a complete Stribeck Curve. Prior to this advancement lubrication testing of a Stribeck Curve has been shown to be evaluated in a stepwise fashion requiring data stitching. This advancement provides precise data throughout lubricant regime evaluation and substantially reduces time and cost. The test also shows a great potential to be used in different industrial engineering applications.

Continuous Stribeck Curve Measurement Using Tribometer

The Stribeck curves were measured using two lubricant oils with different kinetic viscosities for comparison. The Nanovea Pin-On-Disk Tribometer equipped with the lubrication module was used. The rotational speed decreased at an exponential rate from 2000 to 0.01 rpm to showcase the continuous Stribeck Curve measurement and the precise sensitivity of the Tribometer capabilities.

Anodized Coatings Macro Scratch Testing

The process of scratching is simulated in a controlled and monitored manner to observe adhesive or cohesive failures. In this application, the Nanovea Mechanical Tester in its macro scratch testing mode is used to measure the load required to cause failure to anodized coatings produced by different processes.
