Abstract
The irregularity profiles of steel samples after vapour blasting were measured. A correlation analysis of profile
parameters was then carried out. As the result, the following parameters were selected: Pq, Pt, PDq, Pp/Pt and
Pku. Surface profiles after vapour blasting were modeled. The modeled surfaces were correctly matched to
measured surfaces in 78% of all analyzed cases. The vapour blasting experiment was then carried out using an
orthogonal selective research plan. The distance between the nozzle and sample d and the pressure of feed
system p were input parameters; selected surface texture coefficients were output parameters. As the result of the
experiment, regression equations connecting vapour blasting process parameters p and d with selected profile
parameters were obtained. Finally, 2D profiles of steel samples were forecasted for various values of vapour
blasting parameters. Proper matching accuracy of modeled to measured profiles was assured in 75% of analyzed
cases.
