In the present study the mild steel (MS) specimens were coated with Nickel-Phosphorus (Ni-P) using acrylic bath. Heat treatment was carried out on specimens under different temperatures and time periods in an inert atmosphere. The various mechanical and tribological tests were performed on specimens. Using weight loss method, the corrosion nature of the samples under different environments was ...

the commonly used nickel-titanium (niti) archwires in orthodontic treatment are often exposed to fluoride-containing mouthwashes. the aim of this in-vitro study was to evaluate and compare the corrosion resistance of three commercially available niti archwires exposed to 0.05 wt% and 0.2 wt% fluoride mouthwashes.three different types of niti archwires, 0.016″ in diameter, from dentaurum, global...

Metal matrix nano composite coatings possess enhanced properties such as corrosion and wear resistance. This paper aims to study the corrosion behavior of pure Co and Co-BN nano composite coatings deposited with different particles concentration (5-20 g L-1) on copper substrates using electroplating technique. Morphology and elemental compositions of the coatings were investigated by means of s...

Composite materials can be defined as a combination of two or more materials that results in better properties than those of the individual components used alone. These materials have high strength and stiffness combined with low density compared to the conventional metals. Polymers are structurally more complex than metals. Polymer – matrix composites are viscoelastic materials and their mecha...

Ni-P Electroless coatings provide appropriate resistance to wear and corrosion. Co-deposition of particles between layers can improve their properties, especially general corrosion and erosion-corrosion behavior by means of nano diamond as reinforcing particles. In this study Ni-P/nano diamond composite deposition were deposited on steel substrate. Structure of the coatings and corrosion r...

The design and necessity of corrosion-resisting nanocarbon nanocomposites have been investigated for cutting-edge aerospace applications. In this regard, nanofillers, especially carbon nanotubes, graphene, nanodiamond, etc. used to fill in various polymeric matrices (thermosets, thermoplastics, conducting polymers) develop anti-rusting space-related nanocomposites. This review fundamentally emp...

Epoxy resin is widely used in high voltage apparatus as insulation. Fillers are often added to epoxy resin to enhance its mechanical, thermal and chemical properties. The addition of fillers can deteriorate electrical performance. With the new development in nanotechnology, it has been widely anticipated that the combination of nanoparticles with traditional resin systems may create nanocomposi...

background: many attempts have been performed and continued for improvement of dental amalgam properties during last decades. the aim of present research was fabrication and characterization of amalgam/titania nano composite and evaluation of its corrosion behavior. materials and methods: in this experimental research, nano particles of titania were added to initial amalgam alloy powder and the...

Mechanical fastening or riveting of metallic doublers is traditionally used for repairing cracked structures, multi-site or wide-spread darnage and any other common flaws detected during inspection of aging aircraft. This method of repair can severely reduce the initiation fatigue lifetime and the darnage tolerance of the structure [ 1]. Several researchers for example [2-6] have demonstrated t...
