#Researchers probe nanoscale properties and mechanisms of lubricant films The pistons in your car engine rub up against their cylinder walls thousands of times a minute;
The team conducted research to probe nanoscale properties and mechanisms of lubricant films and ultimately uncovered the molecular mechanisms behind a common anti-wear additive.
The tip also provides data on the amount of force necessary to break the additive down into a film that protects the surfaces.
Absent a buffering layer of a protective film, those peaks, known as asperities, would rub against each other
"They found that films only began to form when the tip was slid at a certain pressure.
the faster the films grew. The researchers also found an explanation to why these films grow to a certain thickness and then stop growing."
"It's essentially a'cushion effect, '"Carpick said.""The film that grows is not as stiff as the steel.
When you push on a stiff surface, you get a high stress due to the concentration of force.
The thicker the film, the more it acts as a cushion to reduce the stress that is needed to cause the chemical reactions needed to keep growing.
"The self-limiting nature of the films is beneficial, as they would otherwise quickly use up the small amount of ZDDP in the oil."
and observe the film growth at the same time, there would be no way to connect the pressure threshold with the point at which the film begins to form
and when it stops growing.""This is a fascinating example of what we call'tribochemistry, '"Carpick said."
