Pythian layer for mechanical seal applications

The properties of various physical and chemical films and layers on the outer surface and the inner surface are different. Below the surface is a kind of processing deformation layer, including Beilby layer and deformation layer. The Pythagorean layer is an amorphous layer, which is formed during the polishing process, which not only deforms the metal but also produces oxidized molecules, and is about 70-100A thick. Depending on the processing method, the thickness of the deformed layer is also different. Due to the plastic deformation of the material, the structure of the surface of the machined part will change, and the grain will be refined. The surface grain refinement layer and the change layer of the material structure are as deep as tens of microns. Rough machining extends this layer deeper, even hundreds of microns.　　356.html,
