What type of wear occurs due to micromotion between two surfaces?

The correct answer relates to wear caused by micromotion between two surfaces, which is known as Reibkorrosion or fretting corrosion. This type of wear occurs when there is slight relative movement—micromotion—between two materials that are in close contact but not fully sliding past each other. Such micromovements lead to the repeated abrasion of the surfaces, resulting in wear and possibly the formation of corrosion products due to localized stress and wear.

Understanding Reibkorrosion is crucial, especially in mechanical and structural applications where parts may experience consistent vibration or oscillation, leading to this kind of wear. Proper material selection and surface treatments can help mitigate the effects of Reibkorrosion, thereby prolonging the lifespan of mechanical components.

The other options do not accurately describe this phenomenon. Verzerrung refers to distortion, which may involve changes in shape under stress rather than wear due to micromotion. Entsorgen means disposal and is unrelated to wear mechanisms. Abflachung denotes flattening or reduction in thickness, which doesn't specifically address the wear associated with micromotions. Each of these terms pertains to different concepts within material science and engineering, which distinguishes Reibkorrosion as the correct choice.
