LUBRICATION TESTING ADVANCEMENT: CONTINUOUS STRIBECK CURVE MEASUREMENT!
Irvine, Calif., Oct 24, 2013 – Nanovea demonstrates for the first time the ability to measure a continuous Stribeck Curve. Using the Nanovea Tribómetro 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.

NEXT WEEK VISIT NANOVEA AT MS&T 2013!
MS&T 2013 | October 29-30 Montreal, Quebec Canada. The MS&T partnership of ACerS, AIST, ASM, MetSoc and TMS brings together scientists, engineers, students, suppliers and more to discuss current research and technical applications, and to shape the future of materials science and technology. NACE International will co-sponsor MS&T’13. ►www.matscitech.org
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 Tribómetro capabilities.

Coating Failure Analysis Using Micro Scratch Testing
We must simulate the process of scratch testing in a controlled and monitored manner to observe coating failure analysis. In this application, the Nanovea Mechanical Tester, in its micro scratch mode, is used to measure the load required to cause the coating failure to three separately processed DLC coatings. A 90° Cone, 20μm diamond tipped stylus is used at a progressive load ranging from 0.01 mN to 15 N to scratch the DLC coating. The point where the coating fails by cracking is taken as the point of failure.
Mechanical Stability of Grease Using Tribometer
The Nanovea Pin-On-Disk Tribómetro will be used in rotative mode, linear could have also been used. A steel ball tip will be used against a steel sample coated with lithium complex grease. The load used will be at 5N with a constant speed of 150rpm. Two separately formulated lithium complex greases will be tested for comparative evaluation.

Flatness Measurement of Wafer Using 3D Profilometry
En esta aplicación, el Nanovea ST400 Perfilómetro is used to measure the section of a wafer array. The area measured was selected at random, and assumed large enough in that it could be extrapolated to make assumptions about a much larger surface. Surface flatness measurement, planarity & other surface parameters are used to analyze the surface.
