Keronite coating

[GT40_GearHead]

what the felow gearheads around here know about this, found it by accident when i was looking for an intercooler for a project of mine, it looks like it used to treat forged aluminium pistons


Slug i know you know something about this:mad: .....:D

Do you know anything about hard coat anodizing?? Its alot like that... you give it a bath and it gives you a coat that is harder than tungsten carbide. Google anodizing if you dont know what that is. Or.... google Keronite process or something like that. Pretty neat.

Heres the dict. def. of anodizing

an·o·dize (ăn'ə-dīz') pronunciation
tr.v., -dized, -diz·ing, -diz·es.

To coat (a metallic surface) electrolytically with a protective or decorative oxide.

Other than that I have heard and read little on Keronite. But like I said.. google it and see what its properties are and what it can be used for or on. Maybe you could use it on or in a mod?

Edit:
Okay I just saw something when I googled it. It says its a hard coat coating for light alloys.

Edit2:
Okay here is a pretty good website I found on google.

That will explain everything you need to know... well.. hopefully.

honestly this one has me confused. i cant tell you much.

it stems back to the old USSR... those guys originally developed the stuff. i think it finally came into "mass production" so to speak because of process refinements... just like die shrinks for processors or low-k coatings.

it says its a ceramic, and it says stuff about high voltage oxidization. that tells me that its probably some sort of exotic metal or alloy. it works off the same principle as silver plating a coin, or chrome plating steel, but its a little more violent to sy the least. 80kW or more is a fairly large amount of power to be running through an aqueous solution. that works out to about 6000 volts out of a regular 15 amp wall plug. im sure its higher than that, because you have to step it up through a transformer, and that lowers the current a bit.

i cant find what in the actual coating... patents and all that are in the way. i suppose i could try sifting through the patent office website if there is such a thing and see what i can find. i dont think ill find it though. i can only go on what they tell me. they say there is a substrate so this means the actual coating starts as a piece of metal, and atoms are stripped off. so its either an alloy of a lone metal. they say its an oxide, and that makes sense because metals oxidize in water and at high voltages... and a combination of water and high voltage makes it even easier. at this point it could still be a lot of things... any metal will oxidize if you pump enough energy through it. the one thing that throws me for a loop is the hardness. that shouldnt be possible. titanium oxide is a hardness of 7. tungsten carbide is a hardness of 8 or 9... and keronite is even harder. we're talking like a diamond coating, but its not because diamond is carbon. it would have to be something very close... like corundum (aluminum oxide) on steroids.

actually come to think of it... the resistance to corrosion is a tricky part too. i dont know how long crystals like corundum can stand up to acid and stuff like that.

well, now youve done it. now i HAVE to find out what the hell is going on here. and i have to figure out if i can do something like that. whatever this is... it must have been a HUGE deal for the material chemists when they got it right.

[MitaPi]

So you could pretty much diamond coat something but without the the diamond part of it?? I wonder if the finished product would be heavy or light? If its light just think of the possibilities!

[Slug Toy]

probably about the same weight as any old metal. oxidizing doesnt usually decrease density too much, or increase it either. it DOES allow for a more regular crystal structure, which is why oxides are usually harder than the original metal. but once again... ive never heard of an oxide as strong as keronite.

[MitaPi]

Hey same here... IF it is a legit thing then that would be awesome! I bet the process is a bit tricky or not for just anyone to do though.

did a bit more searching and it seems that hard hard anodizing its not so good for cilinders, it can develop cracks on the edges

found a nice site http://www.keronite.com/

slug i hope you like it :D

[Slug Toy]

oh i already like keronite. its my new goal... forget the lasers, railguns, and all that... now i need to figure out how to reproduce keronite or something similar. i can get the high voltages, and ive got plenty of different metals... so now i just need to start hooking things together to see what happens.

[GT40_GearHead]

me proud

ps do you think we can chat some how

[Slug Toy]

that could be possible... i see you have yahoo. i dont know if yahoo is an instant messaging system but i would expect that it is. i think if you have a .net passport thingy you and i can chat that way... msn to yahoo. ive been able to do that with a few people through their own websites actually.

ive found something interesting. after quite a bit of searching, ive found a lot of between keronite and hard oxides. that leads me to believe that keronite IS a hard oxide.

hard oxides are just metal oxides (Al2O3, Fe2O3, MgO, TiO etc). the trick is their deposition forms very stable crystal matrices and makes the layers very hard. some are harder than others, but i would think that an aluminum hard oxide would be hardest seeming as it makes up corundum, which is second in hardness only to diamond.

hard oxides can still be considered ceramics too. ceramics are usually a metal and a non metal combined in a crystal matrix, or an amorphous solid if there is more than one compound involved. so pure oxides form crystals, but things like BaO****iB (barium oxide, copper nitride, titanium boride) will form a solid with amorphous qualities.

so that gets us one step closer to knowing what keronite actually is. and that gets me one step closer to making it.
