Molten salts are widely used to extract oxides and particulate phases from molten Al and protect Al from oxidization during molten aluminum alloys processing. It was reported that TiCN showed a reasonable stability in molten aluminum during solidification nanoprocessing of aluminum matrix nanocomposites. To further verify the TiCN stability in molten aluminum in molten salt, EDX and TEM were us...

In this work, TiN/TiCN & PN/TiCN multilayer films were deposited by plasma- assisted chemical vapour deposition (PACVD). Plasma nitriding (PN) and TiN intermediate layer prior to coating leads to appropriate hardness gradient and it can greatly improve the mechanical properties of the coating. The composition, crystalline structure and phase of the films were investigated by X-ray d...

Thin films of titanium carbonitride (TiCN) were fabricated by DC magnetron sputtering on medical grade steel. The biocompatibility of the coating was further enhanced by growing hydroxyapatite crystals over the TiCN-coated substrates using biologically activated ammonia from synthetic urine. The coatings were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, scanning elec...

Alumina (Al2O3) composite ceramics with different composition ratio and particle-size distribution were fabricated by the material extrusion photo-polymerization combined process (MEX-PPM) based on additive-manufacturing (AM) technology in our previous work. These particles nanosized Al2O3 (n-Al2O3), micron-sized TiCN (μ-TiCN) Al2O3. Effects of n-Al2O3 μ-TiCN investigated characterizing volume ...

With the increase of elderly population and the health problems arising nowadays, such as cancer, knee and hip joint prostheses are widely used worldwide. It is estimated that 20% of hip replacement surgeries simply fail after 5years, due to wear loosening, instability and infection. In this paper it is reported the study of advanced materials with the ability to overcome some of these drawback...

Characteristics of a design process of a launch lock (LL) mechanism are described. This process began with generation of data that proved a previous design would not perform its function reliably. The redesign was then accomplished through the use of fault tree analysis, which helped make a better connection between requirements and actual failure scenarios. FEA modeling techniques for proper s...

This paper presents an approach for modeling and prediction of both surface roughness and cutting zone temperature in turning of AISI304 austenitic stainless steel using multi-layer coated (TiCN+TiC+TiCN+TiN) tungsten carbide tools. The proposed approach is based on an adaptive neuro-fuzzy inference system (ANFIS) with particle swarm optimization (PSO) learning. AISI304 stainless steel bars are...
