If you combine two or three metals together, you will get an alloy that usually looks and acts like a metal, with its atoms arranged in rigid geometric patterns. But once in a while, under [...]
Zeroing in on ZDDP tribofilm growth

31.07.2017 589 Views

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 [...]
