The other day, before using Maruyama Molybdenum Base Power GX200 for gear oil (for manual transmission and differential gear), I had a question about compatibility with LSD, but this time I received a question about the compatibility with lsD.
Base power GX200 for gear oil is a Kansai area-only product characterized by a very high molybdenum disulfide concentration compared to engine oil.
Since the GX200 can be used without problems with engine oil, the GX200 is recommended when using engine oil first, which shows a faster effect.Of course, if the running cost is acceptable, you should continue to use the GX200.
MT oil change today
RED LINE Super Light Shock Proof was added for about 2.0 liters and GX200 was added at 100 ml (5%).
Daihatsu genuine Super LSD is usually feeling effective only by the amount stepped on in the open
I opened the accelerator in a place where I could increase the speed a little, and tried several tens of kilometers on the mountain slope.
In the continuous corner of the uphill, it was the impression that the effect became stronger by bending.
Friction decline – it was a sliding image, but it was a conflicting result.
I watched a web video related to Maruyama molybdenum.
It has the effect of lowering the surface pressure, the adhesion rate of the oil increases, and the transmission efficiency increases.
Is that something like that?
The base power GX200 for gear oil has a mechanism that has a good effect on lsD operation.
First of all, the term "face pressure", I'm not from mechanical engineering, so I took this opportunity to investigate a little.
The description "contact surface pressure" will come out.It seems to be a force per the unit contact surface when two objects come into contact with each other.
No matter how beautifully finished metal surface, there is unevenness in the microscopic, the condition of the unevenness is surface roughness,
I imagine that the particles of molybdenum disulfide are buried in the recesses of the rough surface and act in a direction where roughness is reduced.
Since the two objects that are in contact with a certain surface are in contact with each other microscopically, the actual contact area is reduced, and as a result, the true contact surface pressure is larger than the macroscopic calculation value.
Maruyama molybdenum base power addition causes molybdenum disulfide electrode particles to be buried in the surface recess to form the surface, and the true contact surface pressure will be close to the macroscopic calculation value, making it smaller than the contact surface pressure before addition.
I think this is the reason why you say that it has the effect of lowering the surface pressure in a web video.
In addition, the effect of the sound of coating seems to be introduced, but as I mentioned before, the dispersibility and adsorption of particles are generally contradictory properties.It is difficult to think that a very dispersible suspension, such as Maruyama molybdenum base power, has high adsorption at the same time, and it is natural to think that buried as described above is occurring.
I think that it settles down to the use that the metal surface is arranged with a high concentration suspension, and the concentration is lowered by the image of the repair maintenance at the time of the oil change afterwards.
So what about the lubricity between surfaces whose surfaces are made of molybdenum disulfide particles?
This is also my imagination, but when I put force face to face with a more beautiful contact surface, I feel that there is an adhesion effect.
I think that it is easy to slip in the slide direction when the oil film is interposed between the two object surfaces facing, but when the surface is beautiful, the oil is pulled out by the addition of strong force between the two objects and adhesion.
Then, when the force for peeling the adhesion is applied to the two-object surface slide direction, the material surface is not worn, the cleavage of molybdenum disulfide particle crystals (hekikai) is lubricated occurs.
When molybdenum disulfide lubricant is introduced, the slip is too good in the friction part inside the LSD, and the essential "effect" will decrease, but the result contrary to the image is thought to be happening in the above-mentioned or high-pressure contact part.
Even if there is no effect of burying the worn metal inside the engine, we believe that it contributes to the reduction of engine oil consumption and noise reduction by adjusting the surface roughness.
I think that oil film retention depends on the viscosity characteristics of the base oil, but the effect of metal surface modification and repair may side by side improve oil film retention.
I'm sorry for the story that I don't want to keep, but I've been able to give you my personal opinion.
We look forward to your continued exchange of views.
