TEMPORARY AGING WEAR OF COBALT BASED ALLOY

Abstract

The study of the properties of amorphous metallic magnetic alloys is one of the most important areas of modern physics. Despite the fact that a large number of scientific research works on the properties of metallic alloys with an amorphous structure have been carried out, many problems related to their properties still remain unsolved. From a practical point of view, this is due to the fact that they have very rare and wide physical properties. Changes in the structure of amorphous alloys leading to their complete crystallization also occur at room temperature, but thermal processing high temperatures requires more time. Therefore, in addition to the selection of the optimal thermal treatment mode for the (CoFe)75Si15B10 alloy, changes in the characteristics and distribution of the magnetization of the amorphous tape occurred in the structure during wear. As a result of the research, it was determined that there were significant changes in the maximum magnetic permeability after heat processing with an optimal isothermal storage time at a temperature of 420 °C in air.
