Wrenches that are recommended for use on GTEs should be plated with which of the following elements?

Correct Answer: Option B — Nickel

Nickel-plated tools are preferred for gas turbine maintenance to prevent corrosion and ensure durability. Unlike some other coatings, nickel plating provides a hard, smooth surface that resists wear and prevents the transfer of contaminants to the high-temperature, high-stress alloys used in modern marine gas turbine engine construction.
