The aim of the present study was to evaluate the influence of multidirectional brushing on the surface roughness, morphology, and bonding interface of resin-repaired CAD-CAM ceramic and composite restorations. Twelve (N = 12) blocks (4 mm × 4 mm × 2 mm for parallel axis; 5 mm × 4 mm × 2 mm for perpendicular axis) of lithium disilicate glass-ceramic...

Abstract A study on the effect of bond coating (BC) surface modifications prior to ceramic deposition is presented. Grit blasting and polishing were used to modify the BC surface finish. Thermal barrier coating (TBC) systems were made of a commercial yttria-stabilized zirconia (YSZ) deposited by electron beam physical vapor deposition on a β -(Ni,P...

This research studies the influence of high-peak loads on local relaxation of residual stress and fatigue damage in highstrength steel welded joints treated by high-frequency mechanical impact (HFMI) treatment. The joint behavior is simulated with elastic–plastic finite element analyses that account for the combined effect of geometry, residual str...

The drive towards decarbonising the electricity grid and the high global warming potential (GWP) of sulphur hexafluoride (SF6), 24,300 times greater than CO2 and with an atmospheric lifetime of 3,200 years, has led to an increasing level of research activity to find a suitable alternative candidate with a significantly lower GWP. This thesis invest...

Dans l’industrie moderne, l'usinage demeure un processus essentiel pour la réalisation de pièces mécaniques complexes. En particulier, l'industrie aérospatiale utilise largement des stratégies d'usinage à grande avance pour réaliser des géométries complexes à partir de bruts en superalliages à base de nickel. Lors d’une étude préalable, un modèle g...

The interactions between soil-structure are largely governed by the shear strength at the soil-structure interface, particularly in situations involving large displacements, known as shear residual strength. This latter can be influenced by a range of factors, including normal stress, physical properties, surface roughness, wall friction. The main ...

In this study, a near-dry electrical discharge machining (NDEDM) process has been conducted using compressed air mixed with a low quantity of biodegradable refined sunflower oil (called oil-mist) to investigate the machining characteristics. The Box-Behnken method looks at how oil flow rate (OR), air pressure (AR), spark current (SC), and pulse wid...

In modern manufacturing, machining remains a vital process for complex mechanical components. In particular, the aerospace industry extensively employs high-feed milling techniques to machine complex geometries from nickel-based superalloys. This study focuses on the analysis and modeling of high-feed milling for Inconel 718 in 2.5-axis machining. ...
