Ask The Expert: Corrosion Under Powder Coating
Q. We’re powder coating on sheets of cold-rolled closed annealed parts. We found that, after some days, the color is peeling off, and we have found corrosion beneath that. Is there a solution, or should we switch to another process?Mechanical Finishing

Flipping the Switch on Anodizing
The idea of using square pulse anodizing is to have a higher average current density for the total process and thereby reduce the process time. When pulsating between two values of current density, a high period and a low period give the aluminum surface time to recover during the low-current-density period.Powder Coating
How Fabricators and Finishers Can Finish the Job—Fast
Fabricators and finishers can work together to reduce lead-time. Sheet metal fabricators and custom coaters—so alike in some ways, unlike in others—sometimes clash. Both juggle myriad orders of varying quantities and due dates, and both measure success on throughput: the more work they ship during a given period, the more revenue they can expect.Liquid Coating
Is Lean and Green Possible in the Finishing World?
Is it possible to be both lean and green in the finishing world? Lean manufacturing says that money spent on resources for any goal other than the creation of value is wasteful and should be eliminated.

Product Quality Means Better Cleaning
Choosing an Aqueous Parts Washing System: As machining technology has advanced, expectations for product quality have increased as well. But better finishes and tighter tolerances are not the only goals. The need for meeting more stringent cleaning standards has gained the attention of many shops.

Ripple Effect: Researchers say leveling of electrodeposits can be achieved by applying a small forcing voltage
Seeking smoother plating deposits? It may be all in the waves. This story looks at studies that have shown that superimposition of a small sinusoidal potential wave (smooth, repetitive oscillation) onto a potentiostatic bias can lead to more level electrodeposits in finishing.Liquid Coating
