Surface Engineering Techniques and Applications: Research Advancements
Magnesium and its alloys are a well-explored type of material with a multitude of applications ranging from biomedical prosthetics to non-biological tools such as automotive components. The use of magnesium and its alloys are highly desired for such applications mainly because magnesium is lightweight...
Surface Engineering by Friction Stir Processing and Friction Surfacing
K. Surekha, E.T. Akinlabi.
This chapter is focused on the recent advances in the solid state surface engineering techniques including Friction Stir Processing (FSP) and Friction Surfacing (FS). The effectiveness of FSP and FS in improving the surface properties is explained in detail along with the principles, applications...
Improving Surface Integrity Using Laser Metal Deposition Process
Rasheedat M. Mahamood, Esther T. Akinlabi, Mukul Shukla, Sisa Pityana.
Laser Metal Deposition (LMD), an additive manufacturing process (also known as 3-D printing) and a non-traditional fabrication process used for improving the surface integrity of components is presented in this chapter. In LMD, parts are manufactured directly from the 3-D Computer-Aided Design (CAD)...
Application of Laser Assisted Cold Spraying Process for Materials Deposition
Monnamme Tlotleng, Esther T. Akinlabi, Mukul Shukla, Sisa Pityana.
The Laser-Assisted Cold Spraying (LACS) process is a hybrid technique that uses laser and cold spray mechanism to deposit solid powders on metal substrates. For bonding to occur, the particle velocities must be supersonic. The supersonic effects can be achieved by passing a highly compressed Nitrogen...
Laser Additive Manufacturing in Surface Modification of Metals
Rasheedat M. Mahamood, Mukul Shukla, Sisa Pityana.
Additive Manufacturing (AM) offers lots of advantages when compared to other manufacturing processes, such as high flexibility and ability to produce complex parts directly from the Three Dimensional (3D) Computer-Aided Design (CAD) model. Producing highly complex parts using traditional manufacturing...
Surface Characterization in Fused Deposition Modeling
Alberto Boschetto, Luana Bottini.
Fused deposition modeling is a proven technology, widely diffused in industry, born for the fabrication of aesthetic and functional prototypes. Recently used for small and medium series of parts and for tooling, it received particular attention in order to integrate prototyping systems within...
Large Amplitude Forced Vibration Analysis of Stiffened Plates under Harmonic Excitation
Anirban Mitra, Prasanta Sahoo, Kashinath Saha.
Large amplitude forced vibration behaviour of stiffened plates under harmonic excitation is studied numerically incorporating the effect of geometric non-linearity. The forced vibration analysis is carried out in an indirect way in which the dynamic system is assumed to satisfy the force equilibrium...
Design and Evaluation of Hydro-Pneumatic Friction Damper Suspension System
S.V. Gorabal, S.N. Kurbet, K.K. Appukuttan.
Perceived comfort level and ride stability are the two most important factors in the evaluation of suspension system in a mobile vehicle. It is extremely difficult to simultaneously maintain a high standard of vehicle ride, handling and body control in the vehicle by using conventional passive...
Recycling of Waste Epoxy-Polyester Powders for Foam Production
Carmine Lucignano, Erica Anna Squeo, Alessandro Guglielmotti, Fabrizio Quadrini.
This paper proposes a new foaming technology (solid-state foaming) to produce structural foams from waste thermosetting resins. The proposed technology is easy and does not require specific and expensive equipments. Solid tablets are produced by cold compaction of resin powder, and foam by heating in...
Laser Sub-Micron Patterning of Rough Surfaces by Micro-Particle Lens Arrays
Ashfaq Khan, Zengbo Wang, Mohammad A Sheikh, Lin Li.
Laser surface patterning by Contact Particles Lens Arrays (CPLA) has been widely utilized for patterning of smooth surfaces but there is no technique developed by which CPLA can be deposited on a rough surface. For deposition of CPLA, conventional techniques require the surface to be flat, smooth and...
Micro Machining of Nonconductive Al2O3 Ceramic on Developed TW-ECSM Setup
