Confused? Say it's not so.
That's ok, it wouldn't be the first time and I'm guessing it won't be the last.

Thanks for the WS2 reference. It's always good to learn new things.
Merry Christmas to you and yours too.
No prob, hope it helps someone . . I only posted it because I didn't see it mentioned in the 50 pages I have read so far, lol. . . Plus Texasstar seems to me to be the type of person that likes tech stuff and isn't afraid to try different things, so I thought it might interest him . . I also read that he seized a cam bearing on one of his bikes and the Tungsten would likely totally eliminate bearing problems even if no oiling mods were done providing one used good oil and kept it clean etc.

That Tungsten Disulphide reference was really interesting though. I'll have to check that out some more. I'll have to see if anyone is using it on two stroke cranks. I have sliver plated big end bearings on order and aluminum caged bearings to evaluate on the drag motor and WS2 might be another technology to look at.
I don't know if they can put it on needle bearings but irregardless, you could definitely put it on the crank pin.
Swaincoat also applies it as well as thermal barriers etc but he mixes his with Moly and applies it much thicker, so I seriously doubt he is using the impinged method and is likely using a binder for it to adhere, which isn't a problem on pistons because all the piston mfg's do the same thing and it holds up fine if good oil is used, but as I mentioned, it's definitely not the method one wants to have on a cam and rockers etc.
As far as finding info on the internet from people that have used it, you won't come up with much but you will see some info if you Google "Micro Blue" and it is the same product and similar application technique . . I just happen to know about it and other coatings from things I have been involved in before.
Another coating that can be impinged is Moly which is extremely similar and another is DLC aka Diamond like Carbon but it requires a base, therefore, it goes on a little thicker than the Tungsten . . It too is popular and is used by some Formula 1 guys on cams and trannies . . It is harder than the Tungsten but it does not hold he oil quite as well and it has a 3 to 5 times higher CF factor, however, that's not a big deal since its CF is fairly low anyway.
The smoother the piece these materials are applied to, the lower the CF will be.
There are some shifter kart pros using it on their 2 stroke pistons and trannies, but they're not telling anyone about it.
