The main aim of the project is experimental research related to friction, energy efficiency, corrosion and wear, sealing, heat generation and heat transfer in fluid power components.
The project concentrates on finding optimal coating materials as well as appropriate surface finishing techniques for components operating in unfavorable operating conditions.
The impact of my work on machining processes of new coated corrosion and wear resistant surfaces will be evaluated; factors considered are: machining costs, surface texture/roughness, impact on fatigue etc.
The outcome will be a comparison between a based material and coated materials such as fatigue testing and measuring parameters of surface integrity.
Surface integrity comprises parameters such as roughness, hardness, residual stresses and structure. Round specimens were produced by turning with two values of surface roughness (Ra 1,6 μm, Ra 3,2 μm). The procedure was carried out in the same way as on the real components in the industry.
The same process was performed on production coated specimens then these specimens were coated through HVOF method. The final roughness was Ra 0,3 μm by grinding. At the end I created the S-N curves for all materials.
The main idea was identifying the influence of surface finish (before coating) on the fatigue life.
Main target: Proposition for good new coating and sealing solutions to upgrade present-day hydraulic products and to increase their competitiveness on markets involving products for demanding corrosive environments.
