DLC possesses higher hardness with high wear resistance, low friction and chemically inert. Abrasive wear of both coated and uncoated specimen will be compared. In conventional bearings, material is subjected to a high cyclic loading and high levels of abrasion, the fatigue, friction and wear. When a bearing fails, it will affect the machine and reliability of the whole system. Therefore, prolonging the service life and reliability of the bearing by improving the wear resistance would be achieved by DLC coating.

In this paper proposes a benefits of additive manufacturing (AM) within prosthetic device manufacturing, especially for the customization of exoskeleton for Muscular Disorder patients. This work starts with patient’s CT scan data of lower limb in DICOM format is exported into MIMICS software to stack 2D scan data into 3D model. Then 3D models are imported in to 3matic software, to modeling a Top and Bottom braces with suitable scaling factor, and create connecting structural arrangements in proper dimensions. Wall thickness analysis has been carried out in 3matic software, to find out the standard deviation of top and bottom braces is valued as 1.65mm.The clinical gait analysis data’s were evaluated and determined, a 100 kg system, the torque required for knee extension during stair climbing was 140 Nm and 50 Nm during walking. The weight of th...

Design/methodology/approach: Weight reduction of the frame was achieved by topology optimization technique. Initially the load and stresses acting on the frame was studied. Material of the frame was chosen as Aluminium and the frame was geometrically modelled using Autodesk Fusion 360. With the help of ANSYS AIM 18.2, weight of the frame was optimized by the design modifications suggested by the concept of topology optimization, for the corresponding loads and stresses induced on it. It was observed that the stress induced on the modified design was lesser than that of respective permissible yield stress of the frame material. After optimization, the weight of the frame was reduced from 3.0695 kg to 2.215 kg with the weight reduction of 27.84%. The weight reduction shows that the topology optimi...

At lower laser powers, able to achieve higher material removal rate in drilling with reduced taper angle and roughness. Design/methodology/approach: Aluminium alloy is a highly reflective material, while laser drilling it ejects plumes, which makes the drilling unreliable. The plume generated due to this action causes deteriorating effects over the work piece as such affecting surface textures. Removal of plume is the major consideration in laser machining process, especially in laser assisted drilling. The plume is a form of cluster of ions having charges in it. Due to the magnetic field input, the ions line the path along the lines of force of magnets. Thus, the ion cloud can be cleared at the localized plane, where the subsequent laser drilling going to be happens, leads to reduced plume thereby reduces the taper angle and s...

It is a continuous problem, difficult to eliminate completely. The cost of metallic corrosion to the total economy is in billions of rupees per year. The inhibiting action of the banana peel extract as a corrosion inhibitor in controlling corrosion of mild steel in 0.1M HCl solution was studied. Corrosion inhibition was identified by employing weight loss measurements and electrochemical techniques. Five samples of mild steel specimen were taken and they are subjected to varying concentration of banana peel extract solution for analyzing the inhibitory properties. The protective film has been analyzed using FTIR spectroscopic techniques. The results indicated that the corrosion rate is decreasing as the concentration of banana peel increases and simultaneously it enhances the inhibition efficiency of the mild steel.
