Purpose: Purpose of this paper is investigation of influence of the surface processing by laser method on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds were tested for three cases: without additional pr...

Cavitation-induced wear, also known as cavitation erosion, can be found in many fluid power components, especially water hydraulics. Cavitation erosion leads to component damage and might even cause system failure. The resistance of various materials when using conventional manufacturing processes has already been investigated the past. In this work, effects additively manufactured on are compa...
