Which statement is NOT a reason to use hardfacing?

• A. Combat wear
• B. Prolong life of an object
• C. Reduce down time
• D. Increase cost of replacement parts

Answer: (D)

Hardfacing adds a wear-resistant layer to surfaces that endure lots of abrasion or impact, so the component lasts longer and sheds less material over time. The main benefits are resisting wear, extending service life, and cutting downtime because components don’t need changing as often. So reasons to use hardfacing include combating wear, prolonging life, and reducing downtime. The idea of increasing the cost of replacement parts isn’t a goal of hardfacing; it would work against its purpose by making components more expensive to swap out. In practice, the upfront effort and materials for hardfacing are justified by lower wear rates and longer intervals between replacements, saving money overall.
