TOPIC:
Optimization of the Determination of Vapor Pressure of Vacuum Grade Lubricants Utilizing the Knudsen Method


ABSTRACT:
In the semiconductor and aerospace industries, the use of materials which exhibit low outgassing properties is absolutely essential to the success of components and systems in high vacuum (very low atmospheric pressure) environments. All components, including the lubricants used in these environments, must possess exceptionally low outgassing properties, as to not contaminate any of the systems in the environment. Simply put, outgassing is when a material is placed into a high vacuum environment, with the addition of heat, and various components of the material are volatized out of the material and into the surrounding environment. This volatilization or evaporation into the surrounding environment can create enormous issues not only in the environment, but on any surfaces on which the evaporated materials may condense on. Understanding how a lubricant will behave in moderate to high vacuum conditions is critical to the success of components used in these environments. Although there are various methods for determining the vapor pressure of various materials, some methods have documented issues with being unstable and difficult to reproduce. The purpose of this study is to develop and optimize a Knudsen method for determining the vapor pressure of various lubricants. Determining the testing variables which produce fluctuations in results along with refining the testing method will lead to the most efficient method for performing these tests. Design of experiments methodology combined with optimization theory is used to design and validate a test method which will produce accurate and repeatable results.
