The traditional Taguchi method is widely used for optimizing the process parameters of a single response problem. Optimization of a single response results the non-optimum values for remaining. But, the performance of a machining process is often evaluated by several quality responses. Under such circumstances, multi-characteristics response optimization may be the solution to optimize multi-re...

Surface characteristics play a very important role in medical implants and among surface features, roughness is effective some applications. Among the various methods used to improve roughness, magnetic abrasive finishing (MAF) process has been widely engineering. In this study, effect of particle morphology along with four other parameters, including type work metal, time, speed operation, pow...

The mixing of Newtonian and non-Newtonian fluids in a magnetic micro-mixer was studied numerically using  ferrofluid. The mixing process was performed in a three-dimensional steady-state micro-mixer. A magnetic source was mounted at the entrance of the micro-channel to oscillate the magnetic particles. The effects of electric current, inlet velocity, size of magnetic particles, and non-Newtonia...

in this research controlled coating of magnetite (fe3o4) nanoparticles with sio2 was investigated. the fe3o4 nanoparticles were synthesized via chemical co-precipitation and then coated by silica according to stober method. effects of tetra ethyl ortho silicate (teos) concentration and ethanol to teos on the coating thickness were investigated. x-ray powder diffraction, fourier transform infrar...

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 titanium. CoBlast is a novel coating technology used mainly in the deposition of ceramics onto this metal. This is achieved by simultaneously blasting a ceramic particulate (the...

Original scientific paper Recycling of all materials should be supported by modern society. Material recycling is one of the most important ways of dealing with waste. One of material recycling possibilities is an inclusion of waste into primary matrices. A suitable ratio and a combination of waste particles influence in a positive way mechanical properties of the material in which they are dis...

The Ice abrasive water jet technology uses cryogenically cooled ice particles instead of the mineral used in Abrasive technology. aim is to avoid contamination workpieces with abrasives and reduce environmental impact this are sucked into a high-speed speeds up 600 mxs-1 using Venturi effect. Direct observation process very difficult due extreme operating conditions. We have clearly shown that ...

Titanium alloys are widely used in aerospace, the military industry, electronics, automotive fields, etc., due to their excellent properties such as low density, high strength, high-temperature resistance, and corrosion resistance. Many components need be finished precisely after being cut these applications. In order achieve high-quality high-efficiency finishing of titanium alloys, ultrasonic...
