1.	Which of the following is/are the causes of catastrophic failures of corrosion?(a) Incomplete weld penetration(b) Extremely porous casting(c) Improper heat treatment(d) Incomplete weld penetration, extremely porous casting and improper heat treatmentI had been asked this question during a job interview.The doubt is from Eight Forms in section Eight Forms of Corrosion of Corrosion Engineering
Answer» Right choice is (d) INCOMPLETE weld penetration, EXTREMELY POROUS casting and improper heat treatment The best I can EXPLAIN: Corrosion is an electrochemical reaction that results in the degradation of a material. Corrosion failures are usually catastrophic in nature. And the CAUSES are incomplete weld penetration, extremely porous casting, and improper heat treatment.
