Surface Characterization after Blasting

Blasting modifies the surface state of materials in terms of surface irregularities too. Bearing in mind that the roughness characteristics affect the components functionality, it is essential to study and evaluation the surface state of pretreated materials. The chapter deals with evaluation of relation between individual surface roughness parameters of the blasted surfaces based on the measured values on the surfaces, which were blasted by various types of blasting materials. Based on the analysis of the results were also proposed sets of surface roughness parameters, which can be used in the assessment of the blasted surfaces. These allow you to effectively distinguish differences in roughness of blasted surfaces from the point of view of other follow-up technologies. It also lists the main factors that affect surface roughness.
