Abstract: Rotating bending fatigue tests have been performed using smooth specimens of a rolled AZ31 magnesium alloy in laboratory air at ambient temperature. Fatigue strength and characteristic was evaluated and fracture mechanism was discussed on the basis fracture surface analysis. Electrical polishing (EP) as well as deep rolling (ball burnishing (BB)) U-notched specimens were performed on ...

• Fused Deposition Modeling has the potential to create customized embedded sensor systems if hybridized with InkJet methods. The as-printed surface finish of printed components results in poor conductivity or continuity breaks tracks. Three finishing methods are investigated: nozzle ironing, subtractive machining and burnishing. Burnishing yielded most desirable results, increasing reducing is...

This study analysed the condition of surface layer valve stems made 317Ti steel after polishing and burnishing. Surface roughness, microhardness, residual stress tests were carried out. The out to determine effect (especially non-standard parameters roughness) on durability valves possibility obtaining a favourable state by means sliding Significant differences observed in values roughness that...
