THE MECHANISM OF THE WHITE LAYER FORMATION IN THE CASE OF THE WEAR OF TOOLS DURING THE FORMING OF STEEL STRUCTURAL PARTS
Journal Title: Tribologia - Year 2011, Vol 238, Issue 4
Abstract
Hot or warm forging of steel structural parts favors the formation of the white layer on the surface of steel tools. The formation of the white layer is the result of tribological processes, and phase transformations in the surface of the tools often plays the main role in the wear mechanisms in these tools. The morphology of the white layer forming on the surface of tools during the extrusion of steel parts of a railway bumper is presented in this work. The research enabled the analysis of the microstructure of the white layer as well as discussions and proposals of a detailed description of the white layer formation mechanisms.<br/><br/>
