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

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

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

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
