ADVANCED SURFACE SUBSTRATE ANALYSIS AFTER ABRASIVE BLAST-CLEANING

Popis výsledku v původním jazyce

Blast-cleaning is one of the often-used technologies of surface pre-treatment. Its main use is in the area of anticorrosive protection of materials, as the last technological operation prior to the creation of protective coating. The basic principle of abrasive blast-cleaning is the hurling with high kinetic energy of blast-cleaning abrasive against the surface of a material. The results are the cleaning of the surface of a material from drosses, rust and other impurities, the creation of a characteristic microgeometry of the surface and also the significant effect on the surface layer of a material. All these parameters have a significant impact on the resulting adhesiveness of protective coating of a material to the base material. The following paper presents a complex analysis and evaluation of the surface of a material after abrasive blast-cleaning. A cylindrical intermediate product was blasted with four different types of media. The analysis of individual surfaces included, for instance: the assessment of purity of a surface according to EN ISO 8501-1, Surface tension measurement of the substrate using test inks, a metallographic analysis, assessment of surface roughness, assessment of microhardness and the analysis of residual stress using the magnetoelastic method. On the basis of these analyses, it is possible to clearly set the optimal parameters of surface abrasive blast-cleaning prior to the creation of protective coating.
