  2. Thermal spraying - Wikipedia

    en.wikipedia.org/wiki/Thermal_spraying

    Plasma spraying setup – a variant of thermal spraying Particle temperature and velocity for different thermal spraying processes [1] Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The "feedstock" (coating precursor) is heated by electrical (plasma or arc) or chemical means ...

  3. Solution precursor plasma spray - Wikipedia

    en.wikipedia.org/.../Solution_precursor_plasma_spray

    Solution precursor plasma spray (SPPS) is a thermal spray process where a feedstock solution is heated and then deposited onto a substrate. Basic properties of the process are fundamentally similar to other plasma spraying processes. However, instead of injecting a powder into the plasma plume, a liquid precursor is used.

  4. Plasma transferred wire arc thermal spraying - Wikipedia

    en.wikipedia.org/wiki/Plasma_transferred_wire...

    Plasma transferred wire arc (PTWA) thermal spraying is a thermal spraying process that deposits a coating on the internal surface of a cylindrical surface, or external surface of any geometry. It is predominantly known for its use in coating the cylinder bores of an internal combustion engine , enabling the construction of aluminium engine ...

  5. Detonation spraying - Wikipedia

    en.wikipedia.org/wiki/Detonation_spraying

    Plasma spraying: another thermal spraying technique similar to detonation spraying. Detonation spraying is one of the many forms of thermal spraying techniques that are used to apply a protective coating at supersonic velocities to a material in order to change its surface characteristics.

  6. Physical vapor deposition - Wikipedia

    en.wikipedia.org/wiki/Physical_vapor_deposition

    Close-space sublimation, the material, and substrate are placed close to one another and radiatively heated. Pulsed laser deposition: a high-power laser ablates material from the target into a vapor. Thermal laser epitaxy: a continuous-wave laser evaporates individual, free-standing elemental sources which then condense upon a substrate.

  7. Spray foam - Wikipedia

    en.wikipedia.org/wiki/Spray_foam

    Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...

  8. List of insulation materials - Wikipedia

    en.wikipedia.org/wiki/List_of_insulation_materials

    This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

  9. Thermal history coating - Wikipedia

    en.wikipedia.org/wiki/Thermal_history_coating

    THCs are applied by atmospheric plasma spraying, which is a thermal spraying technique. This ensures that the coatings are robust to allow long life-times in harsh environments, such as on jet engine components, which experience temperatures in excess of 1000 °C [2] and angular velocities of up to 10,000rpm [3] (revolutions per minute).
