1.	Which of the following is/are the preventions of corrosion fatigue?(a) Use of high tensile strength metals(b) Perform shot penning to induce compressive stresses(c) Use coatings such as electrodeposited zinc, nickel(d) Use of high tensile strength metals, perform shot penning to induce compressive stresses and use of coatings such as electrodeposited zinc, nickelThis question was posed to me in semester exam.My enquiry is from Eight Forms in division Eight Forms of Corrosion of Corrosion Engineering
Answer» Right answer is (d) Use of high tensile strength metals, perform shot penning to INDUCE COMPRESSIVE stresses and use of COATINGS such as electrodeposited zinc, nickel For explanation I would say: Methods to prevent corrosion FATIGUE: • Use of high tensile strength metals • Perform shot penning to induce compressive stresses • Use coatings such as electrodeposited zinc, nickel, chromium, COPPER and nitride coatings.
