We were asked about EN resistance in a media with next components: Ozone- N dioxide - N trioxide- N tetraoxide, demineralized water - gamma rays . We would be very pleased to anybody being able to give us information about this.

What is the substrate and how thick is the Electroless nickel? What is the temperature of the equipment, what are the temperature fluctuations, and how fast does the temperature change?

Probably a bad idea. NOx and water equals nitric acid which attacks EN quite well. As the concentration increases or temperature increases or as time increases, you will lose the EN.
