Zygo Corporation
Roughness Measurements - Let’s Take a Closer Look effectiveness in components that need to retain fluids or gases, like valves or seals, which may lead to leaks. Roughness also concentrates stress in certain areas, increasing the likelihood of fatigue failure under repeated use. Beyond functionality, surface roughness affects other factors as well. Rougher surfaces expose a larger area to corrosive elements, which can speed up the corrosion process. This becomes especially critical in environments where parts are exposed to chemicals or moisture... (read more)Browse Surface Profilometers Datasheets for Zygo Corporation -
