Glassy Carbon manufactured now with Less Heat

22.09.2017 tribonet
Carbon nanotubes lower the transformation temperature of glassy carbon, possibly aiding manufacturers, MIT researchers report. Last winter, MIT researchers discovered that a phenol-formaldehyde polymer transformed into a glassy carbon material in a process similar to baking […]

The Science of Friction on Graphene

12.08.2017 tribonet
  Sliding on flexible graphene surfaces has been uncharted territory until now, Graphene, a two-dimensional form of carbon sheets just one atom thick, has been the subject of widespread research, in large part because of […]

Metallic Glass Gears for NASA Robots

07.08.2017 tribonet
Throw a baseball, and you might say it’s all in the wrist. For robots, it’s all in the gears. Gears are essential for precision robotics. They allow limbs to turn smoothly and stop on command; […]

Zeroing in on ZDDP tribofilm growth

31.07.2017 tribonet
Models for the stress-activated growth of tribofilms from ZDDP were modified to include wear. TWO RECENT CUTTING EDGE ARTICLES reported on work that showed the growth rates of tribofilms from ZDDP were accelerated by contact […]
