Abstract:  
This paper difines one concept to be used for reinforcement of propellers surfaces. During construction and assembly of ships in shipyards, this question always is presented. In the most early phase of design and mechanical calculation of propeller and ships diagrams speeds comes the question, to avoide undesirble phenomenon - streaming of water what can cause cavitation. Many investigation and testing of propellers model in Institutes basins are arranged and organized to find optimal shape to have minimal water resistance and adequate trust force for ship moving. Shot peening is one method and concept for increasing of compressive stresses trust furface of propellers blades.
