Comparative research on an abrasive blasting of C45 steel for various working media

Abstract

This paper deals with the influence of testing elements made of C45 steel after heat treatment. The elements have been machined with various abrasive materials using abrasive blasting: quartz sand, two corundum sizes and two sizes of BrownFused Alumina. The treatment of all types of abrasives took place at the same working pressure. The 2D and 3D roughness parameters obtained after the abrasive blasting were analyzed. Roughness measurements were made using the Talysurf CCI Lite optical profilometer. Microscopic observations were performed on a Nicon Eclipse MA 200 inverted microscope.
