Okay, we can't sing like the Beach Boys. And unlike their California hit song—your vibrations are not good vibrations.

Curious, too, since your contacting metal surfaces are non-moving parts. Closer inspection reveals an external vibration. A small frequency under load is involved. Surfaces are slipping. And wear from oxide debris and fatigue cracking are obvious.

Nothing any dry film lubricant won't solve. Right?

Well, for nuclear plants, you need to consider the negative effects of radiation. Dry lubricants based on dichalogenides contain sulfur and will break down into undesirable, corrosive compounds. The situation is more than mechanical.

Of course, the lubricant must offer load-carrying ability, chip resistance and flexibility. But, only graphite can offer safety and endurance life.

So, while your vibrations in nuclear power generation are not "lovin' good," we can still say graphite dry lubrication will be sweet music to the ears.
