Comparative research on abrasive blasting of 145Cr6 steel for various working media

Abstract

This paper deals with the influence of testing elements made of 145Cr6 steel after heat treatment. The elements have been machined with various abrasive materials using abrasive blasting. The abrasive materials were: quartz sand, two corundum sizes and two sizes of Brown Fused Alumina. The treatment of all types of abrasives took place at the same working pressure of 0.55 MPa. 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.
