Linden Black of Phoenix Electroform Products challenged us for blackening nickel.
We did not have an answer for him so we provided a sample for him to conduct blackening tests to try on his nickel substrate. Lindy liked what he saw visually and now he had to test it with a spectrophotometer to confirm his visual results. He found a value of 0.73-0.75 using the spectrophotometer. Attached is his graph that he developed and placed into the pdf above. Click on the pdf to view graph! To learn more about Ultra Blak 465 click on the underlined area. If you review the previous blogs last April we also used Ultra Blak 465 to blacken Kovar!
