Nanotechnology Repairs Engine Damage in Cars

[silversync]

"Wear and tear on engine components is common because of friction and it happens in all machinery with moving parts. Lubricants that reduce friction can only delay and minimize inevitable damage. The idea of reversing that wear by fixing a worn part was a goal of Pavlo “Pasha” Rudenko, a Washington State University Ph.D. candidate who decided to research the use of smart nanoparticles to replace eroded material. "

"The material, also called nano-flakes, is sticky on one side and smooth on the other. The sticky side is attracted to points of friction and attaches itself to those spots, leaving the smooth side facing out. This happens over and over, building up layers of nanoparticles until a given rough spot is smoothed over, much like filling in a pothole in a street. The heat and pressure that naturally occur with friction bond the nano-flakes together, forming a new, durable carbon-lattice surface that Rudenko calls “diamond-like.”"

My ancient 2.1 WBX will need something before too long. What do you folks think about this?

Wear is not only low spots, or pits. But also scuffs that give raised spots.

i love this! back in the day some of you might remember the "miracle pills" JC Whitney marketed as engine rebuilders. one red sudafed sized pill per cylinder put in thru the spark plug hole, sold in packs of 8 of course, to magically restore compression, oil pressure, and gas mileage. all for $13.95. i think i even bought a set when i was 15. that and the VX6 battery restorative additive. pink tubes of boric acid i assume. bought those too! anything to save actually doing some work.

fast forward 50 years and history repeats itself. bless their hearts for keeping history alive.

nasa has a whole department dedicate to listening to radio signals generated by aliens, and has scientists thinking global warming might be causing extremely cold winters.

Needs Another Seven Astronauts

They have done some cool stuff, and some very questionable stuff too.

The Tech Briefs they publish is simply about stuff that has been funded, a lot of snake oil included

So what happens when this micro rough surface rebuilder chemical fills in all the oil holding cylinder cross hatching marks, and makes the cylinder walls mirror smooth? Dont we call that problem cylinder glazing?

food for thought, kind of like space food sticks.

If you have a coolant leak and instead of repairing the leak you add the GM little vial of silver powder to the cooling system.
Guess what?
It works! It stops your coolant leak!
And
Destroys your radiator and heater core by clogging them up!
But it was an easy coolant leak fix ........

That's a nice watch.

Fortis also had their version

Interesting how the one side of the flake is slick, the other sticky. So when 1 flake settles into a depression and secures itself (statistically possible), it's then presenting its "slick" side to future flakes. They never explain how the next flake will stick to that.

Same with the PTFE oil additives and Slick 50. There is never an explanation of how this "super slick" stuff sticks to an oily bearing. I could see the product settling into low spots in theory, but for it to remain there against the hammering of engine operation and oil flow.... Seems like the cold oil startup would blow this loose debris in the depressions out every morning on cold start and then it would later resettle, etc.

Just never could wrap my brain around it. Also, like most gummint agencies, NASA provides tens of millions of dollars to little companies and startups as grants when they are working on various solutions whose success would help the NASA mission. Some of these work out, most do not. So the claim "NASA developed" is well off the mark. Often it just means they got some of their funding to try to develop something from NASA and has no relation to a performance claim.

Will it fix the notorious hot zones in my air-cooled cylinders too?!

~20 years ago I tracked fuel economy over many fill-ups and over multiple oil changes while always filling up at the same fuel pump. With each oil change I alternated between oil WITH Slick50 and then the next oil change without, then back to Slick50, etc... I consistently got better fuel economy with the Slick50 than without. The difference ranged between 5% and 10% better with it than without. YMMV.
