  2. Tungsten hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Tungsten_hexafluoride

    Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6. It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air). [2] [3] It is the densest known gas under standard ambient temperature and pressure (298 K, 1 atm). [4]

    The reaction of tungsten(VI) oxytetrachloride and hydrogen fluoride will also produce WOF 4. [3] WOCl 4 + 4HF → WOF 4 + 4HCl. WOF 4 can also prepared by the reaction of lead(II) fluoride and tungsten trioxide at 700 °C. [3] 2PbF 2 + WO 3 → WOF 4 + 2PbO. Tungsten(VI) oxytetrafluoride hydrolyzes into tungstic acid. [1] [9] WOF 4 + 2 H 2 O ...

  7. Detonation spraying - Wikipedia

    en.wikipedia.org/wiki/Detonation_spraying

    After a surface has been abrasion blasted and/or machined a thin layer of molybdenum, nickel-chromium alloys or nickel aluminide can be spayed before the final detonation spray coating to improve the bond strength. This is known as a bond coating. Bond coatings are often used when spray coating materials of ceramic composites are being applied.

  8. Thermal spraying - Wikipedia

    en.wikipedia.org/wiki/Thermal_spraying

    Wire arc spray is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then charged and an arc is generated between them. The heat from this arc melts the incoming wire, which is then entrained in an air jet from the gun.

  9. Cold spraying - Wikipedia

    en.wikipedia.org/wiki/Cold_spraying

    The most prevailing bonding theory in cold spraying is attributed to "adiabatic shear instability" which occurs at the particle substrate interface at or beyond a certain velocity called critical velocity. When a spherical particle travelling at critical velocity impacts a substrate, a strong pressure field propagates spherically into the ...
