STICTION Meaning and
Definition
-
Stiction is a term commonly used in engineering and refers to the condition where two surfaces or objects in contact exhibit a static friction that is greater than the kinetic friction between them. It is a combination of the words "static" and "friction." Stiction occurs when there is a resistance to motion when one tries to move an object that has come to rest, typically due to the microscopic imperfections, adhesion forces, or the presence of lubricants.
In practical terms, stiction can often be observed in mechanical systems, such as in the movement of mechanical parts or in the operation of switches and relays. When stiction occurs, an initial force must be applied to overcome the resistance and start the motion. Once the motion is initiated, the friction reduces to kinetic friction, which is generally lower.
Stiction can pose challenges in various applications and industries. For instance, in manufacturing, it can affect the precision and accuracy of machining processes, leading to errors or malfunctions. In nanotechnology, stiction can be a significant concern due to the extremely small scales involved, requiring specialized techniques to control and mitigate its effects.
Overall, stiction refers to the static friction that needs to be overcome to start the motion of surfaces or objects in contact. Understanding and managing stiction is crucial for ensuring smooth operation and functionality in a wide range of mechanical systems and applications.
