Anodizing Clinic: Measuring Color of Coatings with a Colorimeter
Q. Recently, a company asked us to match its samples so we could do work for them. According to our method, we matched the samples, but they were rejected when they were sent to the company. We were told the samples were out of tolerance. We discovered the company used a different brand colorimeter with a different color scale to measure the color. Is there a set standard in the anodizing industry for measuring and matching colors?
Anodizing Clinic: Anodic Coating Blistering on 7075 Alloy
Q. We have recently run into a surface condition when hard anodizing 7075 machined forgings. It seems to be present primarily on the end of the part, even down into the hole. Both of these areas are machined. The condition does not appear to be evident on other surfaces. I have not seen this condition before, but it appears to me to be rather unique and something recognizable.

Anodizing: Corrosion on Hardcoat Anodized 7000 Series Forging
Q. I sent you photos of two parts that are alloy 7050 forgings. On these parts there are spots that appeared as a result of Type III (hardcoat) anodizing that were not present before anodizing. They look like corrosion of some sort, but the corrosion looks a little different on each part. What causes these spots to appear and what measures can be taken to prevent or eliminate them after they occur?
