In this study, a Ti50Al40V10 single alloying target is used to deposit TiAlVN coatings by direct current (dc) magnetron sputtering technique. The structural, mechanical, and frictional properties of final deposited at various N2 content are investigated. It reveals that coating transforms from single-phase (cubic phase) dual-phase structure hexagonal phases) with the increase content. highest h...

The effect of reducing the thinning rate when flow forming AZ31B magnesium alloy barrels on microstructure, crystal orientation, micro-, nano- and macro-mechanical properties was investigated. results demonstrate that undergoes different degrees plastic deformation after forming, grain size dislocation density inside change greatly, evolution pattern organization has a significant mechanical ma...

Indentation hardness and scratch tests are common techniques used in industries laboratories to determine the mechanical properties of thin films. Here, we propose a relative value elastic modulus films composed mixture polydimethylsiloxane polymeric silica with self-healing effects. For this study, homemade nano-indenter nano tester have been designed microscope scanning stage allowing carryin...

Introduction: Resin composites are an important part of restorative treatment in modern dentistry. There are many trademarks available in Iran market and physico-chemical properties of many of these resin composites are not evaluated yet. This study was carried out to evaluate the physico-chemical properties of four available resin composites and also to assess the effect of aging on their prop...

The purpose of this experiment was to determine the hardness values of the hybrid layer and its surroundings through the continuous use of a microhardness measuring device. Black's Class V cavities were prepared in nine dog teeth. The cavities were divided into four groups according to the dentin adhesive system applied. The adhesive systems were: "Bond One System", "Liner Bond II sigma System"...

We present an approach for producing complex nanoscale patterns by integrating computer-aided design (CAD) geometry processing with an atomic force microscope (AFM) based nanoindentation process. Surface modification is achieved by successive nano-indentation using a vibrating tip. By incorporating CAD geometry, this approach provides enhanced design and patterning capability for producing geom...

This paper reports on electrophoretic deposition of hydroxyapatite coatings 316L stainless steel and Ti6Al4V alloy. Coatings were carried out at 60 sec. time voltage values 40, 80, 120, 160 Voltage. Suspension: It was prepared by using Ethanol, Hydroxyapatite, Polyvinyl Alcohol, Sodium dodecyl sulfate, N-N-Dimethylformamide chemicals. The findings results acquired the end study have been presen...
