The John Deere Des Moines Works in Ankeny, IA is thriving, thanks to a combination of state-of-the-art technology and an inventive management philosophy…
Hi-Tech Metal Finishing started as a captive plating shop in 1993, but demand for its high quality, on-time, precision plating of aerospace parts has transformed it from a captive shop to a plating shop where more than 50% of its revenue is generated from outside customers' work...
Hard chromium replacements have been actively sought for decades. In this, the Final Report for the AESF Foundation’s first Research Project since the formation of the NASF, the authors present the results of their extensive research into novel plating processes.
Many industries that require innovative solutions in cost reduction and weight savings are turning to aluminum as a substitute for stainless steel and other carbon steel alloys for parts and components.
How to use it for planning, preventive maintenance and troubleshooting.
This paper will discuss recent research work on the development of a functional trivalent chromium plating process from a single, simple-to-control trivalent-based electrolyte to replace hexavalent chromium plating. Hexavalent chromium plating has been used for many years to provide hard, durable coatings with excellent wear and corrosion resistance properties. However, hexavalent chromium baths have come under increasing scrutiny due to the toxic nature of the bath, effects on the environment and worker health. In this work, we are updating accomplishments to achieve properties comparable to existing hexavalent chromium plating for functional applications. Work on achieving desirable thickness, uniformity, adhesion, porosity and corrosion resistance, as well as other material properties, will be discussed.
