And IT WORKED!
It worked extremely, shockingly well! In over 2 dozen engines so far.
Just as Dr. Ali Erdemir 'suspected' it 'might'.
Dr. Ali Erdemir awarded the prestigious 2024 Tribology Gold Medal
date: 11.11.2024
The Institution of Mechanical Engineers is delighted to announce Dr. Ali Erdemir as the recipient of the prestigious 2024 Tribology Gold Medal.
Dr. Erdemir, a globally recognised expert in tribology, has dedicated over 35 years to advancing the design and development of novel materials, coatings, and lubricants aimed at improving the energy efficiency, durability, and environmental impact of mechanical systems.
Dr. Erdemir began his journey in tribology with an undergraduate degree in Metallurgy from Istanbul Technical University, Turkey. He later pursued graduate studies at the Georgia Institute of Technology, where he earned his Master's and PhD in Materials Science and Engineering in 1982 and 1986, respectively. His illustrious career took root at the Argonne National Laboratory in Illinois, where he conducted groundbreaking research from 1987 to 2019.
Throughout his career, Dr. Erdemir has made significant contributions to tribology. Among his most notable achievements are the discovery of near-frictionless carbon films, boron-based solid lubricants, and superlubricious graphene films. His research has pushed the boundaries of energy conservation and environmental sustainability in mechanical systems, from traditional machinery to electric vehicles.
In recognition of his contributions, Dr. Erdemir has received numerous prestigious awards, including election to the National Academy of Engineering (USA) and the National Academy of Inventors. He is also a fellow of several international organizations, such as the European Academy of Sciences, the World Academy of Ceramics, and the Science Academy of Turkey. Dr. Erdemir has also been honored with six R&D 100 Awards, the Mayo D. Hersey Award from ASME, and the International Award from the STLE, among many others.
Beyond his research, Dr. Erdemir has been a dedicated leader in the tribology community, serving as President of the International Tribology Council (2017-2022) and STLE (2016-2017). He has authored over 250 journal articles and holds 36 U.S. patents, a testament to his prolific and influential career. https://www.itctribology.net/en/news...gy-gold-medal/ |
I worked a few years with a friend's local moving company. His largest, FORD-based box truck developed a heater-core leak. We drained the radiator, capturing all the coolant. Flushed the system once. Added some portion of boric acid to a freshwater radiator fill, and as the engine approached operational temperature, we could hear the water/acid mix boiling out of the heater core breach.
Over time, metallic salts began forming as the escaping hot vapors were exposed to the air, and in a few minutes, the leak was sealed!
We drained off the solution, and re-filled with the coolant, without flushing remnants of the boric acid solution.
When he retired, and sold the business years later, the heater core was still holding pressure.
If the valve, valve seat sealing was okay, an only the piston rings were shot, I can see how 'plating' could close up piston-to-cylinder 'slop', allowing the compression ratio to recover.
Just don't know about every other 'hot' surface that would also see 'plating.'
If the coating acted as a micro-polished surface, it could destroy the engineered 'porosity' of the fluid-separated surfaces, reducing the oil's ability to adhere, then we'd be looking at 'high-pointing', flash-welding-and fracture' and a death spiral of disintegration.
You'd want a thermocouple on the oil filter, and one on the oil pan. If you saw the filter's temperature begin to exceed that of the pan, you'd want to shut the engine down.
OEM bearing journal surface finish tolerances used to be in the 10-microinch range for anything experiencing above 3,000 psi unit loads.
We can't run a higher viscosity oil, as the increased shearing and churning friction will overheat the oil, which automatically reduces its viscosity, a vicious circle.
