New paper offers guidance for operating a vacuum furnace under humid conditions

October 5, 2011

Solar Atmospheres and Solar Manufacturing have jointly released a new technical paper on operating a vacuum furnace in humid conditions.  This educational resource offers an insight and practical solutions based on their vacuum heat treating knowledge and experience.

Humidity, especially paired with high temperatures in summer months, poses a significant challenge to the vacuum heat treating process, states the report. Water vapour contained in humid or wet air can accumulate inside the furnace chamber and hot zone causing production metal parts to discolour or oxidize.  The outcome is unacceptable, especially for critical components like aerospace, electronic, and medical implant materials.

The document explains how the amount of water vapour contained in a specific volume of air is a function of relative humidity, air temperature and other factors.  In addition to an in-depth understanding of the topic, readers can obtain suggestions on how to improve final product appearance and minimize possibility of contamination when faced with high humidity.
