1.	Which of the following is/are the basic requirements for the occurrence of fretting corrosion?(a) The interface must be under load(b) Vibration or repeated relative motion between the two surfaces(c) The interface must be under load and vibration or repeated relative motion between the two surfaces(d) The relative motion should be highI got this question during an online interview.This question is from Eight Forms in portion Eight Forms of Corrosion of Corrosion Engineering
Answer» The correct option is (c) The interface must be under load and VIBRATION or repeated relative MOTION between the two surfaces For explanation: The basic requirements for the occurrence of FRETTING corrosion are: i. The interface must be under load ii. Vibration or repeated relative motion between the two surfaces iii. The load and the relative motion of the interface must be sufficient to PRODUCE deformation.
