Effect of grain size and density of abrasive on surface roughness, material removal rate and acoustic emission signal in rough honing processes
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-08-01)
Article
Open AccessHoning processes provide a special cross-hatch pattern to the internal surface of cylinders that favors oil flow. However, along honing operation the abrasive grains wear out and lose their ability to cut material. The ... -
Laser surface texturing of alumina/zirconia composite ceramics for potential use in hip joint prosthesis
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-06)
Article
Open AccessThe use of metal shell to fix an acetabular cup to bone in hip joint prosthesis carries some limitations, including restrictions in prosthetic femur ball diameter and in patient’s range of motion. These drawbacks could be ... -
Low temperature processing of solution-derived ceria deposits on flat surfaces of 3D-printed polyamide
(2019-06-01)
Article
Restricted access - publisher's policyDoped ceria deposits have been prepared on 3D-printed polyamide-12 components starting from inkjet-compatible solutions in an attempt to functionalize the surface of the plastic part, followed by a low temperature decomposition ... -
Wear and MnS layer adhesion in uncoated cutting tools when dry and wet turning free-cutting steels
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-05-08)
Article
Open AccessFree-cutting steels are developed to produce large quantities of parts with low mechanical behavior, mainly for automotive sector. These alloys contain phosphorous, lead, sulfur, and manganese that help to improve the ... -
On the microstructure effects when using electropulsing versus furnace treatments while drawing inox 308L
(Elsevier, 2019-05-07)
Article
Restricted access - publisher's policyIn the present work, microstructure and texture evolution in a commercial 308L stainless steel wire is assessed by comparing several electropulsing configurations and thermal annealing treatments performed during and after ... -
Joining metrics enhancement when combining FSW and ball-burnishing in a 2050 aluminium alloy
(Elsevier, 2019-06-15)
Article
Open AccessThis report describes the effect of the ball-burnishing process on the mechanical properties of 2050 aluminium alloy that was previously friction stir welded. This process is a fast, environmentally-friendly and cost-effective ... -
Optimal machining strategy selection in ball-end milling of hardened steels for injection molds
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-03-01)
Article
Open AccessIn the present study, the groups of cutting conditions that minimize surface roughness and its variability are determined, in ball-end milling operations. Design of experiments is used to define experimental tests performed. ... -
Friction capabilities of graphite-based lubricants at room and over 1400 K temperatures
(2019-01-02)
Article
Restricted access - publisher's policyThe present work investigates the lubricant capabilities at room and hot-forging temperatures (>1400 K) of three types of lubricants with two different graphite concentrations (8% and 12%). These lubricants are distinguished ... -

Model based on an effective material-removal rate to evaluate specific energy consumption in grinding
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-03-21)
Article
Open AccessGrinding energy efficiency depends on the appropriate selection of cutting conditions, grinding wheel, and workpiece material. Additionally, the estimation of specific energy consumption is a good indicator to control the ... -
Development of a patients-specific 3D-printed preoperative planning and training tool, with functionalized internal surfaces, for complex oncologic cases
(2019)
Article
Restricted access - publisher's policyThe use of physical 3D models has been used in the industry for a while, fulfilling the function of prototypes in the majority of cases where the designers, engineers and manufacturers optimize their designs before taking ... -
Current-induced ductility enhancement of a Magnesium alloy AZ31 in uniaxial micro-tension below 373 K
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-12-31)
Article
Open AccessThe size effects in metal forming have been found to be crucial in micro-scale plastic deformation or micro-forming processes, which lead to attenuation of the material’s formability due to the increasing heterogeneity of ...
