Hi All,
Bit long winded so kindly bear with me.
Bought anodising kit from reputable company and set-up to the letter. Only difference I made was I bought a proper power supply from Amazon.
Ok, piece part area calculated as 0.084 sq ft / 12.09 sq inchs and using 720 calculator I determined 0.5 amps/15v for 120minutes.
Part thoroughly de-greased and etched for 30 secs in Sodium Hydroxide solution, then rinsed in de-ionised water. Part suspended with 3mm aluminium wire and cooked as described, then again rinsed in de-io.
Black dye heated to 40°C and part immersed for 20mins but straight away I can tell the dye is not taking as I'd like. Here my friends lies the problem I just can't get the part as black as night. What am I doing wrong? This is the 5th attempt and I just can't get the parts any darker than a light grey? I also notice there are some lighter patches which I cant explain as I didnt handle this at all between procedures?
Can somebody please advise your help would be invaluable and greatly appreciated. Many thanks in advance
