Nickel alloy hydrogen embrittlement during zinc plating?

Are nickel alloys sensitive to hydrogen embrittlement during zinc plating?

It depends on what you mean by sensitive. Compared to hardened 4340 steel, it is not. Most companies will ask for a timely post plate bake if the hardness of the part is Rc 39 or more, or if it has a very complex geometry or if it is a critical part like part of a jet engine.
