(SPONSORED CONTENT)Low Pressure Vacuum Carburizing of Gears
Solar Atmospheres provides low pressure vacuum carburizing (LPVC) that significantly increases the surface hardness/strength of steel parts for improved friction and wear. Performing LPVC in a vacuum furnace eliminates oxygen and prevents IGO (intergranular oxidation) that is inherent in atmospheric carburizing, resulting in clean parts with less distortion reducing post process finishing operations, and costs.

Many techniques have been developed over the years to control heat treatment distortion, including the use of different quenching medias, optimization of heat treatment cycles, altering the material chemical composition and even press quenching. Now, learn about Quenching in the 4th Dimension! SECO/VACUUM's Tom Hart presented a webinar about 4D Quenching technology, a safe and simple hands-off heat treatment process, minus the challenges of press quenching. Article Courtesy of Seco/Vacuum

Heat treat alternative offers advantages over conventional methods.
ALD-Holcroft Vacuum Technologies Co. will host a two-day technical symposium at the Henry Ford Museum in Dearborn, Michigan September 23â€“ 24, 2008.
The October 2011 issue of Gear Technology featured the article â€śLow-Distortion Heat Treatment of Transmission Components,â€ť which covered the combination of low-pressure carburizing and high pressure gas quenching in an automotive environment. Here, heat treating expert Dan Herring explains why oil quenching is an appropriate choice for many applications.
This paper introduces new process developments in low-pressure carburizing and carbonitriding using either high-pressure gas quenching or interrupted gas quenching.
The complete Events section from January/February 2005, including coverage of a vacuum carburizing conference.
Acetylene with DMF solvent enables benefits of low-pressure vacuum carburizing.
What gear material is suitable for high-temperature (350 â€“ 550 degree C), high-vacuum, clean-environment use?
High demands for cost-effectiveness and improved product quality can be achieved via a new low pressure carburizing process with high pressure gas quenching. Up to 50% of the heat treatment time can be saved. Furthermore, the distortion of the gear parts could be reduced because of gas quenching, and grinding costs could be saved. This article gives an overview of the principles of the process technology and the required furnace technology. Also, some examples of practical applications are presented.

News from around the Gear Industry
The latest technology on display in Columbus, OH. October 24-26.
Suppliers are working hard to make sure their heat treating equipment is controllable, repeatable and efficient, and manufacturers continue to incorporate technology that gives heat treaters and their customers more information about what's going on inside the magic box.
Open any heat treating journal today and youâ€™re certain to find multiple references (articles, technical papers and/or advertisements) promoting low-pressure carburizing (LPC). The uninformed might breeze by these references thinking itâ€™s the next flash-in-the-pan, but unlike in the past, this time the process has legs.
The proper control of distortion after thermal treatment of powertrain components in the automotive industry is an important measure in ensuring high-quality parts and minimizing subsequent hard machining processes in order to reduce overall production costs.
In recent years, improvements in the reliability of the vacuum carburizing process have allowed its benefits to be realized in high-volume, critical component manufacturing operations. The result: parts with enhanced hardness and mechanical properties.
QuesTek Innovations LLC is applying its Materials by Design computational design technology to develop a new class of high-strength, secondary hardening gear steels that are optimized for high-temperature, low-pressure (i.e., vacuum) carburization. The new alloys offer three different levels of case hardness (with the ability to â€śdial-inâ€ť hardness profiles, including exceptionally high case hardness), and their high core strength, toughness and other properties offer the potential to reduce drivetrain weight or increase power density relative to incumbent alloys such as AISI 9310 or Pyrowear Alloy 53.
The data discussed in this article was taken from an upright vacuum cleaner. This was a prototype cleaner that was self-propelled by a geared transmission. It was the first time that the manufacturer had used a geared transmission in this application.
The heat treatment processing of powder metal (PM) materials like Astaloy requires four steps -- de-waxing, HT sintering, carburizing and surface hardening -- which are usually achieved in dedicated, atmospheric furnaces for sintering and heat treat, respectively, leading to intermediate handling operations and repeated heating and cooling cycles. This paper presents the concept of the multi-purpose batch vacuum furnace, one that is able to realize all of these steps in one unique cycle. The multiple benefits brought by this technology are summarized here, the main goal being to use this technology to manufacture high-load transmission gears in PM materials.
