Abstract

A study is made of the influence of temperature on the rheological properties of electrorheological fluids containing hydrated alumina in the form of pseudoboemite. It is shown experimentally that such electrorheological fluids possess thermal stability, preserving high indices of electrorheological activity (ER activity) up to 120°C. The use of pseudoboemite as a filler of electrorheological fluids will make it possible to ensure efficient operation of electrically controlled hydraulic devices with an extended temperature range of application.
