MolyFusion-Nano Corrosion Test


Corrosion Resistance Testing - Testimonial

Jonathan, as I told you on the phone, it has been too cold at night to run a salt spray test in my shop. However, in the interest of making some progress, I did a "quick and dirty" corrosion test and the results actually look quite promising.

The red are verbal and written comments to Jonathan Doege after the writing of this testimonial.

Here is what I did: I bead blasted and degreased a piece of hot rolled mild steel bar stock. I divided the bar into sections with duct tape. I heated my basement shop to 80 degrees f and let everything acclimate for 3 hours.

See photo ABOVEfor the following:
I applied Eezox a known anticorrosion product to section 1.
I applied FP10, another known product to section 2.
I applied "Molyfusion" to section 3.
I applied "Molyfusion Slick" to section 4.
The rest of the bar was left in the bare bead blasted condition. The two Molyfusion products were applied with a cotton Q-tip by swabbing about once a minute for 20 minutes each. The reason for this is the current application directions, based on experience call for a 20 minute treatment period. My observations hold to the 20 minute treatment period for the following reasons:
The color change in the MolyFusion, did not begin to take hold for 5-10 minutes, and did not achieve uniform color until 15-20 minutes. The MolyFusion-Slick, however, the color was reacting within the early minutes, and did not change (darken) further, to my observation after 10 minutes. It was at least 5 minutes faster than the MolyFusion, bearing out the claims that it reacts faster. The final color after 20 minutes is also a little darker looking with the MolyFusion Slick as compared with the MolyFusion.

The bar was placed in a glass tray supported by two plastic rods in a flat position. It was then sprayed using a spray bottle with an approximate 5% salt-water solution. It was sprayed twice a day for three days (six applications). The salt-water was allowed to puddle and dry between applications. Observation: It only "beaded" on the FP10, which acted like a oil lubricative, but stayed flat or "satin" on the other three test surfaces.

As you can see from the photo, Eezox did pretty well as expected. It is the known control to help verify the hour-equivalency of the rust test. FP10 did not do very well.
Molyfusion. [After 36 Hours (Half way through the test) Rust Crept up from the bottom edge (Where there was not a bit of treatment) creeping slowly and uniformly up into the treated area from the side. This did not occur to except at maybe a miniscule and not visible in the picture to the MolyFusion Slick. MolyFusion and MolyFusion Slick were equal for this period of time as to penetration through the surface. The creepage on the MolyFusion appeared to be a galvanic reaction to the rust. However there was no rust-through of the MolyFusion. Molyfusion with the nano lubricant did very well. It clearly supersedes the others, but when testing was stopped all three other products were in there own particular state of failure or fail-through. 72 hours of intense abuse. The MolyFusion with the nano lubricant is looking good, and MolyFusion without it was going to be completely rusted due to creepage-takeover of all of the surface. Considering it is a "permanent" coating, I think it shows real promise as a corrosion preventive coating.
Especially for springs and internal gun parts, possibly even as an alternative to bluing on external surfaces. It has a terrific "tactical-gray" color it would be called, and I speculate that in a plastic container alone or in a container containing and ultrasonic transducer would present a great dip for cleaned gun chrome-moly steel for self-creating the beautiful cosmetic and clearly rust-resistant finish.
I am excited about this possibility, as I am sure many gunsmiths (good ones, anyway) will be as well.

On the equivalency: Eezox is known to survive 100 hours of salt spray per mil of depth, and I had in the range of 1.5 and 2 mils of depth, which means this test is 150 - 200 hours of 100 degree salt spray equivelence. As you can see the Eevox failed, and the steel appears as if it has been dragged out of ocean sea water. The salt spray percentage was more like 7.5-10% concentration rather than the 5%, which makes for more aggressive corrosion. Also the aeration of the fine mist gets the oxygen involved, and the drying brings the corrosive action to higher concentrations than found in salt spray alone. The first spray was at 100 degrees F (The liquid) and all subsequent spray at the ambient room temperature. Sandblasting has been shown to change steel to its most reactive state, which should be a plus for accelerated rusting of any exposed non-reacted surface. MolyFusion reaction would need to be at 100% to be effective. It may also be a plus for cleaning the metal and its quickest reaction with both the MolyFusion slick and the MolyFusion no impact on the Eevox. The end results of the MolyFusion-Slick are clearly superior to some paints, and give me the impression of a rust-resistant plating rather than a coating.

I also treated the action parts of a Glock pistol with "Molyfusion Slick".
(Static Treatment Only - No wet was introduced prior to the assembled bearing surfaces moving). These parts had the plating stoned off.
(The plating finish contains Moly compound in the pores, and I was afraid this would interact or prevent any serious treatment). It appeared that the conversion took place, but I did not notice any improvement in the feel of the action and the coating seemed to wear off the contact points after a couple of dozen cycles. I was not concerned about this as the contact area is on the edges only. This would be a good area for the Moly Fusion grease to be developed - If the Moly Fusion stays active, the treatment will not go away. This is an unfair static test of the MolyFusion-Slick alone, due to excessive pressure on a knife edge. It was not applied dynamically, the best way to apply it.

After this limited experience with these products, I would feel comfortable using the "Molyfusion Slick" on internal gun parts including springs as a corrosion inhibitor. Now that I have seen the way the product behaves, I don't think it is necessary to do any life tests on springs. I don't think it will have any effect on spring longevity that I can measure given the limited sample size I could test.
