Re: [Vo]:Superelastic metals LENR cathode material prospects?
In reply to Horace Heffner's message of Fri, 29 May 2009 01:43:54 -0800: Hi, [snip] Superelastic metals, like CuSn, InTi, TiNi, and MnCu, may be LENR cathode prospects because they have a resistance to cracking, as well as the possible ability to reconstitute after degassing. http://en.wikipedia.org/wiki/Nitinol Nitinol, a TiNi alloy, is rumored to have links back to Roswell material discussed earlier here. It is easy to speculate it has energy related applications. Unfortunately, Nitinol is subject to hydrogen embrittlement. Here is an interesting solution: http://www.finishing.com/381/17.shtml It was found some years ago that hydrogen embrittlement could be alleviated by ion implanting the surface with platinum. The embrittlement comes from atomic hydrogen diffusing into the surface, not molecular hydrogen. Platinum acts as a catalyst, accelerating the recombination of atomic hydrogen into molecular hydrogen. Implantation works well because the whole surface gets covered, and the amount of platinum needed is negligible. If you try it with a coating, the coating can't have any pinholes. Either way you'll have problems if the parts have internal surfaces. Interesting the material lattice can apparently handle hydrogen in molecular form in the interior without cracking. Unfortunately, hydrogen in molecular form has little prospect for fusion. But, who knows what the prospects for superelastic metals are for LENR, or hydrino formation, until they are investigated? Superelastic metals may provide an excellent matrix for support of implanted hydrino catalysts for use in a hydrogen diffusing environment. The best diffusion rate is likely obtained using a thin film, which coincidentally is exactly what was found at Roswell.

Atomic hydrogen has a much larger radius than molecular hydrogen. Molecular hydrogen plus atomic hydrogen may catalyze hydrinos, so ionic hydrogen driven through such a layer could constitute a hydrino factory. Once formed, hydrinos should diffuse through the lattice rapidly. Other catalysts (than Pd) might be of similar use as well, but with improved characteristics. It has already been shown that driving hydrogen through layers of material (e.g. CaO) within Pd causes transmutation. The point of my post is merely that it is reasonable to investigate other than pure elemental lattices, like Pd, Ni, Al, and Ti, for supporting transmutation layers, and superelastic metals provide a sensible place to begin a search due to their favorable characteristics. The subject also handily relates to the Roswell Debris Confirmed thread.

If I recall it was so thin it could be wadded up into a ball so small it could disappear, and some reports said it was so thin and light it could float in air. Of course I make no assertion of reliability regarding either my memory or any sources of information regarding Roswell or UFOs in general. I would guess the notion the foil was used as the skin of the object relates more to the balloon explanation. Best regards, Horace Heffner http://www.mtaonline.net/~hheffner/

I guess I just didn't expect you to first propose the platinum treatment as a solution to embrittlement only to then point out the flaw in the process. I would also note that adsorbed hydrogen is in an *ionic* state, not an atomic state. ... nuclei leaving the lattice can grab a free electron on the way out. The diffusing hydrogen nuclei are principally ionically bound to conduction band electrons. Is this a description of metallic Hydrogen (since the same can be said of metal atoms in a metal)? Molecular hydrogen plus atomic hydrogen may catalyze hydrinos, I don't think so. The Hydrogen molecule isn't a Mills catalyst AFAIK. However the Hydrogen atom itself may be/is (at least when there are two them acting together, i.e. three individual atoms in all [not two of them combined in a molecule]). so ionic hydrogen driven through such a layer could constitute a hydrino factory. Once formed, hydrinos should diffuse through the lattice rapidly. Other catalysts (than Pd) might be of similar use as well, but with improved characteristics.
