Last night I plated some parts and they came out the best I've ever seem. The only changes made were the temp of alodine droped from 70 to 60. I did add enough alodine to bring it up 1 point. I also did a bucket test (with fresh alodine and water) and found some material that will not mix...
Thanks,
The acid is 2 to 1 and is hard to get off. The hot stray does help but I was told that the parts should be rinsed in cool water for the best results. The main problem I'm having is parts turn out to light. 2024 doesn't seem to color at all but if you get the part wet it shows up gold...
The water is well water (Hard water). Any idea where to get a ph test to go that low? What is added to incread ph? I recently increased the temp to 70deg for the alodine and parts have come out lighter. Would the temp increase have anything to do with it? Should I be aciding the parts...
Sorry for the lack of info pretty new to this. 6061-t6 and 2024-t3 for mat. mostly thru holes. The alodine is 600 series. The alodine strength is at it's max. I haven't been able to find a ph tester that goes under 4 but it is under 4. What do you meen by DI water?
Thanks,
Chris
I recently started alodining parts so any advice would be apreciated. My process now is as follows:
1. clean parts with diswasher.
2. acid dip 3-4 min.
3. spray with hot water.
4. soak parts in room temp water 3-4 min
5. dip parts in alodine for 3.5-6 min
6. let parts air dry 30 sec...
