roughnessrelated
Roughnessrelated is a term used to describe phenomena, properties, or models that depend on surface roughness. It signals that surface topography influences the outcome, often in a scale-dependent manner. It is not a physical quantity, but a qualifier.
In tribology and contact mechanics, roughness-related factors affect real contact area, friction, wear, sealing, and lubrication
In optics, roughness-related scattering occurs when roughness is comparable to or larger than the wavelength. This
In acoustics, surface roughness scatters sound, influencing impedance and the character of reflected sound in rooms
In electronics and sensors, roughness affects contact resistance, electrode adhesion, and tunneling in micro-contacts. Rough surfaces
Measurement and analysis rely on profilometry, atomic force microscopy, and related methods. Common metrics include Ra,
Applications span manufacturing quality control, surface engineering, optical coatings, acoustical materials, and microelectromechanical systems, where controlling
