Electroless and electroplated nickel
I would like to ask why electroless nickel is more corrosion resistant than electroplated nickel?

Electroless Nickel uniformly plates / covers all the intricate portions of the component that is being plated. In a way it covers/closes all pores of the underneath substrate. Once the entire area is covered, the plating rate goes slow.
Since the entire area is plated/covered, it is corrosion resistant. In electroplating, there is no uniformity on the plating surface. This depends on the plating current density etc.,
Hope I answered your question.

The difference in corrosion protection is that Electroless Nickel is in reality an alloy deposit, mainly phosphorus. In order for the Electroless Nickel to achieve its potential as a better corrosion protection you need at least 25 microns.
I hope this helps,
