Al-12.5 wt% Si alloy powder with 15 SiCp was mechanically alloyed (MA) using attrition mill in purified nitrogen atmosphere. The MA processed found to have nano grain size and uniform distribution of the AlSi matrix. This used for atmospheric plasma spraying (APS) varying distances currents densities. coatings obtained were studied by image analyzer, SEM XRD. Microhardness wear rate evaluated Vickers indenter pin on disk type tribometer, respectively. Adhesion strength measured interfacial...
The microstructure and mechanical properties of plasma sprayed nanostructured 2024Al alloy were investigated before after adding SiC particles on weathering steel (Cor-Ten A242) substrate. Mechanical alloying (MA) was used to synthesise the 2024Al–15 wt-%SiC composite powders. X-ray diffraction studies showed p embedment in Al matrix MA nanograins powder coatings. It found that porosity level coating reduced 2% hardness increased 3276 MPa. high adhesion strength coatings observed can be...
Heat transfer enhancement is still needed for the compactness and its smaller temperature difference of evaporator. This paper introducing a mathematical model (Tailor-Chandra Model) energy transport in plasma sprays process droplet. The useful calculate heat through surfaces processed by thermal spraying. describes fluid flow particle droplet during spraying different energies: Thermal Energy (ETh), Surface (ES), Kinetic (EK) lost way radiation (ER) before deposition on substrate. A dynamic...
For the preparation of copper nanoparticles several methods, i.e., thermal reduction, mechanical attrition, chemical reduction metal vapour synthesis, radiation laser ablation and micro emulsion techniques were developed in past. Electrolytic deposition is one most suitable, simplest low cost methods which are used for wide range materials. In present investigations, efforts put to produce nano powder using electrolytic technique. It could be possible obtain near 258 nm size high cathode...
Laser beam machining is presently an widely used technique at the industrial level. Among various operations, drilling with help of laser beams has assumed great significance. In this paper, fundamentals drilling, factors affecting accuracy and reproducibility consequent development suitable techniques have been discussed briefly special reference to high temperature ceramic products. The suitability multipulse (MPT), a considered be most for products, critically reviewed.
An attempt has been made in this paper to improve upon the properties attained cast 2014–based metal matrix composites (MMCs) with SiC dispersoids through extrusion under optimised conditions. The have compared between and extruded MMCs terms of microstructure, physical, mechanical sliding wear properties, improvements attained. Attempts analyse obtained results microscopic investigations on tested samples.
