TUNGSTEN DISULFIDE VS EXAGONAL BORON NITRIDE BRASS FRICTION TEST

- Test di lubrificazione su rullo di ottone con metodo Timken.
Lubricity test on brass roller with Timken method.
challenges with the test include unknown particle size. Also, probably need an ultrasonic mixing method as these powders don't stay suspended well after sitting. It also seems the quantity of material for the volume of fluid is quite high. Interesting none the less.

Thank goodness I have found this channel...its fantastic...
Love how your methods got more scientific from your first WS2 video. Also like that stop-motion-y type frame rate, it somehow makes everything so much more visually pleasing on these types of videos. Do you edit the audio too?
Anyway love what you’re doing and I hope your efforts start to catch on, even if only within a niche of the gearhead community.
Thank you, I'm glad you like my tests!
No the audio is not modified, in fact at times you can hear the birds chirping or my dogs barking in the background...
Molto, molto interessante. Uso questi prodotti e ne posso parlare bene, ora ho anche la prova visiva che funzionano.
Guarda anche questo...

Non mi spiego il perché ma il WS2 e l' h-BN insieme danno un risultato ancora migliore...
Dovresti testare i 5 migliori olii dei risultati con i 5 migliori additivi, ad esempio, ogni olio con 5 diversi additivi, cosi faresti un lavoro fantastico!
Thank you very much.
....now I get what you're up to. I just had to relax.
The boron stuff looks just like liqui Molly ceratec the boron based additive
&
The ws2 looks just like risolene prime the ws2 additive.
What size is need to pass through oil filter?
Is this the same BN we use in makeup ??
can yu suggest the right oil for the mercedes sprinter Van diesel 6cyl, i was looking at Lorenzos or Amsoil or Archoil. additives as i am in Canada I was using Motul but i DO NOT HAVE A DEF SYSTEM ON MY vAN. thansks
So which is better? I see ws2 falls out of suspension faster than hbn but do they both adhere to metal in a similar way. Even if ws2 has lower friction than hbn, if its in suspension for less time, does it make it overall better for engine oil?
Also FYI Your title has a typo, missing the H on hexagonal
Do they use MoS2 as well?
Please, tell, what is the particle size (um/nm) of the powders WS2&hBN you used in test?
0,4~07 micron
Have you thought about trying graphene powder? (Not graphite) they say even 0.01% makes a big difference.
Upvote!
If they are very good why hypoid differencial oils dont use these additives? Are they ok to use in ball bearings?
some motor oils use them as an additive in low concentrations (below 100ppm) because solid additives cause deposit problems
@@edogsx Thanks. Are these additives suitable for differencials with bearings?
@ sellers of this type of additive say yes but I honestly wouldn't do it, at least not at the dosages they recommend.
solid additives tend to settle and aggregate, in ball bearings they can also modify the clearance tolerances
@@edogsx Thank you. I was also wondering about problems like that. But there is almost no information about it. At least i cant find what i am looking for. Thank you.
I have a question are you using standard chemical grade boron nitride or are you using boron nitride nanoparticles?
The manufacturer claims a particle size of 0.4 / 0.6 micron.
I would have thought Tungten compounds as well as Boron Nitride to be abrasive given they are hard materials. How does this lend itself to an obviously lower amount of friction? What's the theory behind it?
WS2 and h-Bn have a two-dimensional platelet structure and a high hardness which results in a very low sliding friction coefficient.
The theory is that very small particles of this material mechanically adhere to the metal surfaces of the engine creating a hard and sliding boundary layer thus reducing friction.
Your doubts are legitimate and I share them ...
.....it's interesting huh. Tungsten carbide for example is an abrasive whereas the sulphide is a lubricant. Diamond is extremely hard whereas graphite being a different carbon allotrope is a lubricant. Sodium is hazardous and chlorine is deadly but we like salt in food .
Haha yup.
Tool steel can be made into files that could cut your engine, or it could be made into balls that would make very low friction bearings.
@@edogsx and also h-BN has enormous heat conductivity, a little greater than copper and little less than silver
How to avoid that the hBN settle?
don't worry about it
hBN weighs less than 1/3 of WS2
it does settle a little bit after a long time, but not nearly as bad as WS2
so basically they are both the same?
I guess hBN is the winner since it's lighter and won't settle as fast
someone should do a test how quickly they settle including MoS2^^
You should try mix both of it
Good idea!
Here It Is!

Can tungsten disulfide be mixed with a full synthetic fishing reel oil for spool bearings? How do I apply it to the bearings?? Please help!🙏
Yes, Ws2 can be mixed with any oil or grease, you can mix oil and Ws2 in a container and then inject it with a syringe ...
Thank you so much sir!🙏I’ve been trying to get someone to answer that question for about a week now🙂
Sir! If I have a 0.4oz bottle of synthetic reel oil how much tungsten disulfide powder would I mix in? Thanks 🙏
@@wretched_spawn8694 0,4 oz equals about 12 ml. In engine oil the mixing ratio is 5g/10g of WS2 for 1L of oil.
Therefore you need to use 0,12g of WS2.
Nanoslick Lubricants makes a fishing reel 🎣 grease, and possibly an oil, with ws2 in it.
Please fix the title - "Hexagonal" not "Exagonal".
If you need to show friction vakue, you must using the microscope on friction surface. Understand ?
Use Iron, Aluminum instead of brass
I tried aluminum and steel but I abandoned them because they didn't give an accurate result.
with brass, on the other hand, I have much more consistent and precise results.
