Effect of impingement angle and impact velocity on slurry erosive wear behaviour of particulate reinforced aluminium composites
http://www.inderscience.com/link.php?id=136661
The influence of impact velocity (10, 20, and 30 m/s) and impact angle (45°, 60°, 75°, and 90°) on the slurry erosive wear behaviour of SiC-reinforced Al 2124 matrix composite was determined. The composite was synthesised by powder metallurgy route and the optical microscopic image confirmed the uniform distribution of SiC particles in the Al 2124 matrix. The microstructural analysis of the eroded surfaces showed that micro-cutting, ploughing, craters, and particle pull-out were the primary material removal mechanisms. The mass loss was observed to increase by increasing the impact velocity and the maximum mass loss was reported at 45°-60° impact angles with 30 m/s impact velocity. The XRD analysis revealed that there was no quartz inclusion on the eroded surface. The inconsistent microhardness values resulted because of the exposed SiC particles on the surface and the crater formation. The variation in average roughness significantly increased by increasing the flow velocity.

Ultraprecision error compensation turning for high-gradient aspheric surface based on B-axis platform
http://www.inderscience.com/link.php?id=136662
High-gradient aspheric elements need to meet the requirements of both high-gradient aspheric characteristics and a streamlined shape in aerodynamics. The shape characteristics of high-gradient aspheric surfaces bring great challenges to machining. Aiming at hard machinability of single-point diamond turning high-gradient optical opponents, an ultraprecision <i>XZB</i> axes single-point diamond turning technique was presented based on rotation <i>B</i>-axis platform. Through analysing the traditional <i>XZ</i> axes turning method, the new <i>XZB</i> axes turning process was proposed to fabricate a high-gradient aspheric surface. The influences of setting errors and cutting edge of arc lathe tool in <i>Y</i>-direction and <i>X</i>-direction on profile accuracy were analysed for correcting the new tool position. The compensation turning method of axisymmetric surface was presented. An error compensation turning experiment of copper was proposed and carried out to obtain a high-gradient aspheric surface. After three time cycles, the profile accuracy was improved from <i>PV</i> 590 nm to <i>PV</i> 103 nm.

Effect of ceramic particles on the mechanical and tribological properties of short carbon fibre reinforced epoxy composites
http://www.inderscience.com/link.php?id=136663
In this investigation, an effort has been made to develop the short carbon fibre stiffened epoxy composites (CFSEC) mixed with multi-walled carbon nano-tubes (MWCNT) and silicon carbide particles (SiCp) using a compression moulding process. The content of MWCNT varied as 0.5%, 1%, and 1.5%, and SiCp content was maintained at 10% by weight of the composite. The impact of the ceramic particles on mechanical characteristics such as hardness, tensile, flexural, and wear behaviour of CFSEC was investigated. For all the mechanical characteristics, the rise in the proportion of MWCNT in the composite has shown a significant improvement. The specific wear rate (SWR) and coefficient of friction (COF) of the composite were studied using the pin-on-disc tester. The wear parameters yielding the lowest SWR and COF were identified from the wear testing process parameters. The fractography analysis of tensile specimens was carried out using a scanning electron microscope (SEM).

Nanofibre composite PCL/HA coating by spray method on metallic implant materials for medical applications: a study on the different spraying distances and pressures
http://www.inderscience.com/link.php?id=136668
Surface modifications and implant coatings are implemented to control the contact between an implant material and a corrosive medium, which can delay the onset of damage and improve the implant performance, such as osseointegration acceleration. There are several limitations associated with surface modification, including low porosity, slow fibre production rate, high production cost, and complexity in the production process. Therefore, this study concentrated on modifying the surface of metal implant materials using a spray method to overcome those limitations and to obtain the porous nanofibre morphology with high coating adhesion property. A spray method was used to form a nanofibre polycaprolactone (PCL) /hydroxyapatite (HA) composite coating. The composite solution was sprayed onto the substrate surface with variations in air pressure of 350 and 450 kPa, with a distance between the nozzle and the substrate from 10, 15, 20, 25, 30, to 35 cm.

Tribological characteristics of carbon fibre reinforced epoxy composite filled with ceramic particles: influence of multi-walled carbon nanotubes
http://www.inderscience.com/link.php?id=136678
In this experimentation, an endeavour has been taken to develop the short carbon fibre (SCF) reinforced epoxy composites mixed with multi-walled carbon nano-tubes (MWCNT) and silicon carbide particles (SiCp) using a compression moulding machine. The quantity of MWCNT was modified by 0.5%, 1%, and 1.5%, and SiCp quantity has been taken as 15% by weight of the composite. The influence of the ceramic particles on the wear characteristics of SCF stiffened epoxy was explored. The wear testing variables, namely normal load, sliding speed, and sliding distance, were considered for the dry sliding wear test. As per the ASTM standards, the wear test was executed utilising the pin-on-disc apparatus, and the composite's rate of wear and friction coefficient were studied. The worn-out area on the wear test specimen was examined utilising a scanning electron microscope (SEM) to recognise the wear mechanism of the composites.
