To prevent carburization, select alloys with a strong surface oxide or sulfide film former such as ________.
A) Silicon
B) Molybdenum
C) Aluminum
D) Both A and C

Question

Quizplus · Accepted Answer

Both silicon and aluminum are strong surface oxide formers and can help prevent carburization. Molybdenum is a good sulfide former but not as effective at forming strong surface oxide films. Therefore, the best choice(s) are A and C.
