the passivation and the corrosion resistance of metal systems by alloying, i.e. introducing components which directly facilitate passivity (for instance Cr, Si, Mo when added to iron) or introducing components which lower the cathodic polarization (Pt, Pd and other noble metals for stai[translate...
GDXJ has pulled back a bit after testing 7-year resistance while GDX has pulled back after hitting a key pivot point and 50% retracement of the bear market. The metals (gold and silver) have yet to hit resistance at $1800 and $18.50, but we can call it close enough. The chart below...
It is interesting to note in this regard that there is a direct relation between the temperature coefficient of resistivity of metals and the coefficient of expansion of gases . The RTDs of general usage are of platinum, nickel and copper. Platinum sensors Platinum being a noble metal , is ...
In some embodiments, the free layer 502 may include multilayers based on transition metals like cobalt and iron, and noble metals such as platinum, palladium, and gold. Some examples include cobalt/palladium, cobalt/platinum and cobalt/nickel. Reading data from an MTJ 500, in various embodiments...
of a given assembly, it may encounter different kinds of metals, metals with or without zinc coatings, different stack up thicknesses and different numbers of sheets to be welded, for example. The previously known analysis techniques were not adequate to contend with the many variable conditions....
