Operating A Vacuum Heat Treat Furnace Under Humid Conditions
A specific concern to a vacuum furnace user is processing critical work during summer months with high temperatures and high humidity. Â This same concern could also be a problem on rainy winter months. Â Under these difficult conditions, it is most important to understand the impact that humid conditions can have on the final surface condition and appearance of the processed parts. Â Work discolored or oxidized by residual water vapor is unacceptable and must be controlled for many critical components like aerospace parts or medical implants and instruments. Â This paper will try to explain factors relating to humidity, air temperature, and methods to improve final product appearance and minimize possibility of contamination.
