Parameter....

Parameter

Parameter: A measurable factor relating to several variables, loosely used to mean a thermal spraying variable, spraying condition, spray rate, spray distance, angle, gas pressure, gas flow etc.

Particle size

Particle size: The average diameter of a given powder or grit granule

Particle size distribution

Particle size distribution: Classification of thermal spray powder materials as determined by various testing methods defining the particle sizes and quantities in a given sample

Particle size range

See Particle size distribution

Pass

Pass: A single progression of the Thermal Spray Gun across the surface of the substrate

Plasma

See Arc Plasma

Plasma Spraying

Plasma Spraying: A thermal spray process in which a non-transferred arc is produced by ionizing an inert gas that then forms the heat source in to which thermal spray materials are injected which are then subsequently propelled to the substrate to form a thermal spray coating.

Porosity

Porosity: Cavity type discontinuities within a thermal sprayed coating

Powder

Powder: Thermal spray material manufactured in to finely divided particles. When explicitly blended for thermal spraying these powders generally fall between an upper limit of 125 microns and 5 microns.

Powder Alloy

Powder Alloy: Powder prepared from a homogenous molten mixture of elements. All of the subsequent particles have approx the same composition

Powder Blend

Powder Blend: A mixture of two or more alloy powders.

Powder Composite

Powder Composite: Two or more independent materials combined to form a single integrated unit.

Powder Feeder

Powder Feeder: A device for transporting powdered materials to the thermal spraying equipment.

Powder Feed Rate

Powder feed rate: The quantity of powder introduced in to the thermal spray process gases per unit of time.

Preheat

Preheat: The heat applied to the substrate immediately before depositing a thermal sprayed coating

Primary Gas

Primary Gas: The major gas used within the Plasma Spray process usually Argon or Nitrogen
