Summary for dichromate dip after en Discussion
The thread asks whether a sodium dichromate dip after EN plating improves wettability, and why. The original poster says parts dipped in a sodium dichromate tank seem to have better wettability after electroless nickel (EN) plating. Marlon L. Cordez asks for a clearer definition of wettability before offering more specific comments. Based on the excerpt, the discussion does not provide a technical explanation or a confirmed mechanism; it mainly shows that the effect was observed by the questioner and that the term itself needs clarification. The practical takeaway is that the apparent improvement in wettability was noted on EN-plated parts, but the thread excerpt does not establish whether sodium dichromate is truly responsible or under what conditions it would help.
Q. Does Sodium Dichromate help in wettability? Why, if yes? Background: I am dipping the parts into a tank containing the above chemical and it has better wettability. The part was coated with EN plating.

Q. I am using sodium dichromate too on EN plated items. Please define wettability further so that I could give some points.
Thanx
