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

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

Vacuum pumps have been called the heart of a vacuum system. Let’s look at how we can reach low vacuum levels using diffusion pumps. And we need to know how all pumps should be maintained to keep the vacuum system running trouble free. by Daniel H. Herring

In order to create a vacuum within a closed container, or vessel, we need to remove the molecules of air and other gases that reside inside by means of a pump. The vacuum vessel and pumps (mechanical, booster, diffusion, holding) together with the associated piping manifolds valves, gages and traps comprise a typical vacuum system. by Daniel H. Herring

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

As of late, it seems everyone is seeking change. Change can certainly be a good thing, but there are times when change – for change sake – is not good. Research for our recent editorials on global warming and China have provoked thought in this area. by Reed Miller

Be careful what you ask for … you just might get it. Just ask the coalition of Industrial Energy Users in Ohio. In the late 1990s, they lobbied hard for electricity deregulation. As a result, Ohio Senate Bill 3 was passed in 1999, which established a framework to “deregulate” energy pricing by allowing the market to set the price for energy through supplier competition. by Nick Zingale
