WebMar 20, 2024 · PAD is a form of cardiovascular disease (CVD) because it affects the blood vessels. It's usually caused by a build-up of fatty deposits in the walls of the leg arteries. The fatty deposits (atheroma) are made up of cholesterol and other waste substances. The build-up of fatty deposits on the walls of the arteries makes the arteries narrower and ... WebPhysical vapour deposition (PVD) is a thin-film coating process which produces coatings of pure metals, metallic alloys and ceramics with a thickness usually in the range 1 to 10µm. Physical vapour deposition, as its name implies, involves physically depositing atoms, ions or molecules of a coating species on to a substrate.
