FilamentsThe tungsten elements in a bulb that glow to produce light. | |
Filiform Corrosion (Spidering)A paint defect caused by moisture ingress between the substrate and the paint film, e.g. via an untreated stone chip, that continues to travel in 'spidery' threads. | |
Filler NeckThe connection into the fuel tank for refuelling. | |
Fillet RadiusA machined curve between two faces of a component. An example is the curve between a crankshaft web and journal. | |
FilmA very thin continuous sheet of material. Paint forms a film on the surface to which it is applied. | |
Film ThicknessThe thickness or depth of a dry paint film is important. Thin films may appear to be the wrong colour due to their lower opacity, and may also have durability issues. Over-thick films are likely to crack in use. The thickness of paint films on iron or steel surfaces is easily determined with a magnetic gauge. | |
Film Thickness GaugeA device used to measure the coating thickness on a substrate. Magnetic devices are used to measure the thickness of ferrous metals; whereas electronic devices are used on non-ferrous substrates. | |
FilterA fine mesh or paper screen used to remove dirt and other contaminants from a liquid or gas (air). | |
Final DriveThe gearing immediately before the driven wheels. It provides a split to each driven wheel with a final gear reduction for the transmission. Can also be used to turn the drive through 90° with the use of bevel gears. | |
