Friction testing, along with wear resistance testing, measures the friction properties of a product, and the result is usually calculated using the coefficient of friction. Friction occurs between moving parts. For example, the power transmission system in cars and trains uses many parts, including clutches, gearboxes, and drive shafts, which are called contact parts. Friction causes heat generation and wear in these parts. Heat generation and wear due to friction are responsible for most mechanical system failures, and the economic losses resulting from such failures are significant. To reduce these losses, tribological tests are performed to evaluate the properties of parts and the materials used for these parts through friction, wear, and wear resistance tests.
In friction, wear and abrasion resistance tests, a test piece and an interface surface are interacted in relative motion to measure the coefficient of friction and wear volume. The friction coefficient is a value that shows the effect of the contact surface on the friction force. Classified as dynamic friction coefficient and static friction coefficient, this value varies depending on the material and surface treatment. In industries where contact fittings are used, there are many instances of evaluating changes in material through friction, wear and abrasion resistance testing as part of product quality assessment, commissioned analysis, and research and development of new products. Such cases are seen as essential tests for quality assurance in a wide variety of industries involving contact fittings such as lubricant and grease manufacturers, suppliers of bearings, pulleys and other parts, and engine manufacturers.
The friction test, along with the wear resistance test, measures the friction properties, and the result is usually calculated using the coefficient of friction. A wear test, on the other hand, measures changes in conditions caused by friction and results from deformation, scratches, and indentations in interacting surfaces.
The coefficient of friction is found by measuring the friction force with a gauge, measuring the load power of the driving motor, calculating from the friction and vibration damping behavior, or calculating the maximum static value.
