Air filter
Mechanism for cleaning air of contaminants such as water, oil and solid matter.
Atomization
Production of a fine spray of liquid particles.
Dew point
The temperature at which air becomes saturated with water, that is, when the air is at 100 percent relative humidity. Below this temperature, moisture will condense and produce dew or fog. As air cools, the amount of water vapor it can hold decreases.Fatigue failure
The fracture of a material due to cyclic stresses or loads.Fretting
A type of wear that occurs between tight-fitting surfaces subjected to cyclic relative motion of extremely small amplitude.
Galling
A condition caused by excessive friction between high spots in a material resulting in localized welding with subsequent spalling.High efficiency particulate air (HEPA) filter
An air filter that removes 99.97 percent of all particles larger than 0.3 microns.
Plastic deformation
Deformation that remains permanent after removal of the load that caused it.Shadow mask
A protective device that partially shields the area of work, thus permitting some overspray to produce a feathering at the coating edge.
