The COVID-19 occurrence is causing a global request for effective measures aimed at mitigating the infection spread. Facemasks have been identified as an essential device people to protect themselves well others from aerosol containing virus. provide critical barrier, reducing number of infectious viruses or bacteria in exhaled breath. present review describes most relevant literature studies on materials and processing technologies used facemask development testing. Antibacterial antiviral...
Abstract Composite coatings (CECs) are providing a unique technological advantage for improving mechanical and tribological surface properties. Among different methods, electrodeposition is one of the most exploited to produce composite on metal substrates. However, process parameters affect graphene distribution, coating morphology performance. This paper investigates how deposition conditions influence inclusion large Graphene nanoplates (GnPs) in Nickel matrix Set condition such as...
Laser beam cutting is a non-contact, production-flexible and highly productive technique that allows accurate profiling of wide range sheet materials. To these further benefits, laser machining increasingly being adopted by industry. This paper investigates the effect material type, workpiece thickness, speed assistant gas pressure on cut quality for industrial-relevant applications using CO2 laser. AlMg3 aluminum alloy, St37-2 low-carbon steel AISI 304 stainless were selected to represent...
Mechanical sliding contacts often experience high wear rates due to significant friction. Recently, self-lubricating coatings, particularly metal matrix composites (MMCs), offer promising solutions with adaptable microstructures incorporating solid lubricants. This study investigates the tribological performance of hybrid multilayer Nickel-graphene coatings a PTFE or Nickel top coating. The tests performed reveal superior PTFE-containing attributed enhanced lubrication and load support; in...
Co-cemented tungsten carbides, namely, hard metals are largely used to manufacture high wear resistant components in several manufacturing segments. Coating with superhard materials like diamond is of utmost interest as it can further extend their useful lifespan. The deposition coatings onto WC-Co be extremely complicated a result poor adhesion. This essentially ascribed (i) the mismatch thermal expansion coefficients between and WC-Co, at typical temperatures inside chemical vapour (CVD)...
Metal additive manufacturing is a major concern for advanced industries thanks to its ability manufacture complex-shaped parts in materials that are difficult machine using conventional methods. Nowadays, it increasingly being used the industrial of titanium-alloy components aerospace and medical industries; however, main weakness structural fatigue life, which affected by surface quality, meaning micro-cracking small defects induced process. Laser finishing Abrasive Fluidized Bed proposed...
In this work, the feasibility of laser surface finishing parts obtained by additive manufacturing (AM) was investigated. To end, a 450 W fiber (operating in continuous wave, CW) adopted to treat Ti-6Al-4V samples via electron beam melting (EBM). During tests, different energy densities and scanning speeds were used. order assess quality treatment, either as-built or treated analyzed means three-dimensional (3D) profilometer, digital microscopy, microscopy. Analysis variance (ANOVA) performed...
The present investigation deals with the definition of a new eco-friendly alternative to pretreat Co-cemented tungsten carbide (WC–Co) substrates before diamond deposition by hot filament chemical vapor (HFCVD). In particular, WC-5.8 wt %Co were submitted thermal treatment continuous wave-high power diode laser reduce surface Co concentration and promote reconstruction WC grains. Laser pretreatments performed both in N2 Ar atmosphere prevent substrate oxidation. Diamond coatings deposited...
Metal-matrix composites are of increasing interest in various industrial fields. The graphene reinforcement phase within the metal matrix structures makes it possible to enhance their properties and, thus, performance many contexts use. Nickel is one most widely used materials create such due its mechanical and anti-corrosive qualities. In particular, nickel coatings produced by electrodeposition. Despite being an extremely mature process, production composite not trivial, as morphology film...
Drag finishing of brass (Cu-30 wt.% Zn) rings using fluidized abrasives, which is a new technology, comparatively evaluated with centrifugal disk finishing. The comparison was performed by selecting the same abrasive granulates two different sizes and operating equipment for processing time or at their respective maximum speeds. experimental analysis investigated change in workpiece morphology, material removal during dimensional accuracy. results showed that each types study were capable...
intermediate temperature, i.e. 170°C, seems to give the best results in term of improved mechanical properties and also aesthetical appearance wood surfaces.
The manufacture of open cell metal foams by dissolution and sintering process (DSP) is the matter present work. Aluminum were produced mixing together carbamide particles with different mesh sizes (i.e., space-holder) very fine aluminum powders. Attention was first paid at understanding leading phenomena stages manufacturing gets through: Compaction main constituents, space-holder dissolution, powders sintering. Then, experimental tests performed to analyze influence several parameters,...
