Air Forces of Nature: Corrosion control office helps prolong life of aircraft
The Air Force Corrosion Prevention and Control Office at Robins Air Force Base in Georgia employs only 17 people, but its small staff plays a big role in keeping aircraft and ground equipment operating throughout the Air Force. The specialists in the office, which is a unit of the Air Force Research Laboratory at Wright-Patterson Air Force Base in Ohio, serve as the corrosion control experts for the entire Air Force.

Tumbling to the Finish
The Flow-Clad system of coating smaller parts at higher production rates uses a tumbling method not usually found in many custom coaters. “I just don’t think too many people even know that this process exists,” says president Bob Zimmerli. “It will definitely save them money. It’s just getting the customer to understand what we can do for them.”

Corrosion Resistance Mechanism of a Chromium-Free Zinc-Flake Coating Film on Scratched Areas -
Chromium-free zinc flake coatings (zinc-rich paint) are used for automotive parts and construction parts, etc. that require a high degree of corrosion protection. The demand for this process is extremely high due in part to its being an environmentally-friendly, chromium-free process. Currently, the automotive industry and others are looking for this type of coating which exhibits superior performance. In 2008, we studied the high corrosion resistance mechanism of the chromium-free zinc flake coating film using polarization curves. Currently, we are working on studying this mechanism in greater detail, focusing on how corrosion is controlled, even on areas that are scratched.

Cobalt-Free Technology for Trivalent Chromates on Zinc Plating
Corrosion and appearance requirements for plated steel parts continue to increase, while at the same time ever more restrictive environmental regulations are being put into place. As if these hurdles are not challenging enough for both process suppliers and applicators, there exists the compelling directive to reduce costs. Much of this is initially introduced by the European automotive industry, but then quickly spreads to automakers worldwide and to most other industries. In the field of zinc plating, the focus is on the protective conversion coatings and top coats that are applied to the zinc deposit. This paper examines the advantages of new cobalt-free technology as well as what is on the horizon regarding future requirements and regulations for zinc plating.

Rent an E-Coat System? Now You Can
Imagine turning space usually set aside for storing parts needing to be shipped out for e-coating into an actual e-coat assembly, one that a plant could lease for a specific job and then turn it back in when the job is finished.

PCX PREVIEW: Precision Cleaning
In the finishing world, there are four common precision cleaning processes: hydrocarbon, aqueous, semi-aqueous, and vapor degreasing. Each has its strengths and disadvantages, but one of the biggest problems with aqueous and semi-aqueous cleaning is the quantity of electricity they take.

Painting on Oil ... Rigs that is
When part-time oilman Terry McIver went to Brady, TX in 2004 to buy a used drilling rig, he was surprised to find the company he was visiting was going bankrupt and had just two employees left from over 200 it had a year earlier. Brady left with the oil rig, but a few months later he went back and bought the company.
