Plasma modification of gallium. Ga.

New gallium. Ga.

In the video: At the bottom of the glass Petri dish is a layer of a conventional metallic Ga at T ~ 20 ° C – the usual solid gallium. As usual layer of gallium (in the form of a solid film) is free to move the ball a liquid the “new plasma” of gallium under the same atmospheric conditions. The ball of liquid “new plasma” Ga at T ~ 20 ° C.

T₀ ~ 30 ° C; The new “liquid» Ga: T₁ ~ 15- 20 ° C;

Gallium under normal conditions has a phase transition temperature “metal” < => “liquid» T₀ ~ 30 ° C; Plasma modification of gallium significantly reduces the temperature of the phase transition to T₁ ~ 15- 20 ° C; Gallium new unique properties as a liquid after plasma modification stored for a long time (verification was conducted for 1 year = 365 days) in the open atmosphere.

Materials with new physic – mechanical, thermal properties (gallium and others) obtained from a unique plasma technology – good heat transfer fluids for Magneto – Hydro-Dynamic engine. New materials – Effective cooling (heating) for the cooling circuits of nuclear reactors and high-power power plants.

Plasma-chemical modification of the metal.

Water-repellency treatment. Hydrophobicity Aluminum (Al).

Usually aluminum. Water sliding angle of ~ 30 °. Initial material. Limited angle ~ 30 °

After plasma modification (hydrophobic) Aluminum angle sliding water ~ 10 °. After plasma modification. Limited angle ~ 10° Hydrophobicity.

The technology of plasma modification of metal – protection technology, preservation of metals from water, frost, corrosion.

Nanocomposite structural alloys

with plasma-modified Nano additives

Nanocomposite alloys Al-Mg + FCMWNT (~ 1%)) Alloy 1000g / ~ 10g FCMWNT modifying plasma. Aluminum-magnesium alloy with multi-walled carbon nanotubes modified plasma becomes high hardness, strength, new energy properties.

As a result, plasma modification on metal, on the subject produced thin (N x 10 nm), the volume-stitched, gas-tight, inert, resistant to acid, alkali and biologically active media, invisible, do not change the appearance of the object, resistant to UV radiation coating. The coating can be removed from the surface completely or partially in the right place if necessary for the restoration of a rarity. The properties of the material object and its appearance does not change.

The plasma processing technology, cleaning, sterilization, hydrophobic – a unique technology for the protection and preservation of archival, historical and cultural values of paper, papyrus, bone, stone, ceramics, wood, metal, textiles, paintings, pictures and other materials.
