Zeroing in on ZDDP tribofilm growth

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 […]

Keeping the Wind in Your Sails

Just like any mechanical device, a wind energy system needs timely, appropriate lubrication in order to function reliably and predictably. Wind turbines routinely withstand extremely demanding conditions: vibration, high mechanical loads, contamination and moisture are […]
