**4. Conclusions**

The production history of materials leaves characteristic features on the surface that affect their behavior during other technological processes. This chapter is focused on the issue of morphological changes that occur on surfaces after abrasive blasting. These changes in terms of roughness need to be monitored as accurately as possible with the whole set of surface roughness parameters, not only from a 2D but also a 3D perspective. This gives a comprehensive view of the blasted surface. At the same time, the factors that contribute to these changes must be taken into account. These are mainly the technological conditions of blasting and the type of blasting abrasive. By their suitable choice, it is possible to achieve the most suitable surface pretreatment by abrasive blasting with the required morphological, tribological, and other properties.
