surface roughness
[/ˈsɜːrfɪs ˈrʌfnəs/]
nounpl: surface roughnesses
rugosidade de superfície
1. The measure of the texture of a surface, quantifying deviations from ideal flatness or smoothness
The surface roughness of the metal component was measured at 3.2 micrometers.
A rugosidade de superfície do componente metálico foi medida em 3,2 micrômetros.
2. In manufacturing and engineering, the degree of irregularity or asperity on a finished surface
Proper polishing techniques reduce surface roughness and improve product quality.
Técnicas adequadas de polimento reduzem a rugosidade de superfície e melhoram a qualidade do produto.
3. A characteristic that affects friction, wear, and adhesion properties of materials
Surface roughness plays a crucial role in determining the friction coefficient between two surfaces.
A rugosidade de superfície desempenha um papel crucial na determinação do coeficiente de atrito entre duas superfícies.
This is primarily a technical term used in engineering, manufacturing, and materials science fields. Both in the US and Brazil, it is standardized terminology used in industrial quality control, automotive production, and precision manufacturing. In Brazil, the term 'rugosidade de superfície' is widely adopted in technical documentation and ISO standards.
