The not-for-profit Performance Review Institute (PRI) administers Nadcap. By Arshad Hafez

 
What Do We Really Know About Tempering?

Tempering, also known as “drawing,” is one of the most common heat-treatment processes – and one that is all too often taken for granted. We all know it’s important, yet we spend little time focused either on the process or on the equipment in which it is performed. By Daniel H. Herring

 
Operation, Maintenance and Troubleshooting of Oil Diffusion Pumps

Maintenance of oil diffusion pumps is key to optimal vacuum furnace performance. The following describes the workings of oil diffusion pumps and indicates the best investment of limited maintenance resources. A small in-vestment in planned maintenance can yield a high return in the ongoing high-level performance of your vacuum system. by Varian, Inc., Vacuum Technologies

 
It's Time to Clean Up Our Act!
As heat treaters, one of our New Year’s resolutions should be to clean up our act! Cleaning parts before and after heat treatment is a critical part of what we do. Most of us feel we clean parts “good enough” and feel we know what cleaning is, but few actually do. by Daniel H. Herring
 
HVOF Production of Hard Chromium Substitution Coatings for Improved Wear
Wear need not be catastrophic to cause substantial reductions in the operational efficiency of production equipment due to increased power loss, equipment downtime and lubricating-oil consumption subsequently leading to the replacement of equipment components. Thus, component wear necessitates an ongoing need to develop components with improved wear performance. by L.C. Casteletti, A. Lombardi Neto, G.E. Totten
 
The Carbon Age

Carbon-based products – since the invention of synthetic graphite over 100 years ago – are an integral part of our lives. They are somewhat like the BASF commercial. “We don’t make things, we make things better.” by Joseph Labant

 
Nadcap for Aerospace Success
Heat Treatment is one of 15 special-process and product programs operating within Nadcap. The Heat Treatment program has seen significant growth since its launch. In fact, in the last 10 years, the number of audits conducted annually has grown by over 400% from 157 audits in 1996 to 655 audits in 2007 at the time of print. The Heat Treatment program accounts for almost 18% of all Nadcap audits conducted in 2007 throughout the world. by Arshad Hafeez
