Introduction Adhesion is the tendency of dissimilar surfaces to stick to one another. It can be measured in terms of work of adhesion in J/m2. It is the energy needed to separate 1m² of joined […]

Introduction Surface roughness measurement is the measurement of the small-scale variations in the height of a physical surface. This contrasts with larger-scale variations such as form and waviness which are typically part of the geometry […]

Introduction: Wear Particle analysis (WPA) is important to identify the wear mechanism in a system. For complex systems where it’s unusual and highly difficult to perform analysis under a microscope or to check for weight […]

Introduction: In the entire world there are no smooth surfaces ideally. Asperities, shape, and height variations all allow us to identify surfaces. Depending on the scale used, even surfaces that appear to be well polished […]

Introduction: Metal surfaces, particularly those of steels, require unique surface treatments to achieve the appropriate properties. Although there are several surface treatment procedures, surface coating techniques are the most popular. Coatings can provide a wide variety of qualities, […]

Definition Surface roughness is defined as the irregularities which are inherent in the production process (e.g., cutting tool or abrasive grit). It may be the result of vibrations, chatter, or work deflections and strains in […]

Introduction The surfaces that undergo friction wear and are lubricated in the mechanical components are called tribological surfaces. These surfaces have different surface topography depending on the type of applications. Most commonly tribological surfaces are […]

Introduction The lubrication regime that occurs due to the elastic deformation of the lubricated contacts is the elastohydrodynamic lubrication regime. This lubrication regime is important for all lubrication regimes to understand because of its application […]
