Machinability of Al 6061 Deposited with Cold Spray Additive Manufacturing
LUPOI, ROCCO; ALDWELL, BARRY (2017) -
A new Approach for experimental evaluation of contact stresses
LUPOI, ROCCO (2005)n metal forming operations, t he intensity and distribution o f stresses at the tool/material interface have great influence on the pattern and mode of deformation. This is due to the effect ... -
Nozzle-internal particle velocity measurements and loading effect on particle acceleration inside a Cold Spray nozzle
LUPOI, ROCCO; Meyer, M.; Caruso, F. (2017)The advantages of the solid state deposition process Cold Spray (CS) over conventional spray technologies go hand in hand with the requirement of high and well-predictable particle velocities. The ... -
Particle Image Velocimetry (PIV) of Cold Spray of particles in supersonic nozzles
LUPOI, ROCCO (Trinity Centre for Bioengineering, 2015) -
Particle speed analysis in CoBlast
LUPOI, ROCCO (2015)The deposition of well-adhered thin type of coatings is of great importance in manufacturing and is used in numerous applications. Of particular interest in the biomedical sector is the deposition of hydroxyapatite onto ... -
Performance characterization of Ni60-WC coating on steel processed with supersonic laser deposition
LUPOI, ROCCO (2015)Ni60-WC particles are used to improve the wear resistance of hard-facing steel due to their high hardness. An emerging technology that combines laser with cold spraying to deposit the hard-facing coatings is known as ... -
Powder stream characteristics in cold spray nozzles
LUPOI, ROCCO (2011)The exponential increase of industrial demand in the past two decades has led scientists to the development of alternative technologies for the fast manufacturing of engineering components, aside from ... -
Revolutionary devices to dissipate energy in mechanical systems
LUPOI, ROCCO (2006) -
Solid-state manufacturing of tungsten deposits onto molybdenum substrates with supersonic laser deposition
LUPOI, ROCCO (2014)Near fully dense tungsten coatings onto molybdenum substrates have been demonstrated using the Supersonic Laser Deposition (SLD) process. This is a characteristic that is not readily achievable with refractory materials. ... -
A STUDY ON INTERNAL DEFECTS IN FRICTION STIR WELDING OF ALUMINIUM ALLOYS
LUPOI, ROCCO; MCFADDEN, SHAUN (2014)Friction Stir Welding (FSW) is a solid state welding process that offers advantages over the conventional techniques. As it is a solid state process, re - solidification defects like porosity ... -
Supersonic Laser Deposition of Tungsten
LUPOI, ROCCO (2014)Near fully dense tungsten coatings onto molybdenum substrates have been demonstrated using the Supersonic Laser Deposition (SLD) process. This is a characteristic that is not readily achievable with ... -

Thermal-hydraulic performance of convective boiling jet array impingement
LUPOI, ROCCO; ROBINSON, ANTHONY (2016) -
Under surface pressure sensing technique for the evaluation of contact stresses
LUPOI, ROCCO (2005)In metal forming operations, the intensity and distribution of stresses at the tool/material interface have great influence on the pattern and mode of deformation. This is due to the effect of frictional forces, being ... -
UREAD impact behaviour using Non-Newtonian materials
LUPOI, ROCCO; LUPOI, ROCCO (2015) -
Use of concealed pressure pins to determinate contact stresses in ring compression
LUPOI, ROCCO (2005)new flexible experimental technique is introduced where a tool base that incorporates sensitive pressure pins is used. An industrial - tool that contains the forging geometry can be placed on top of the ...
