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...

TiO2 nano-particles were used in electroless plating bath to obtain Ni/P/nano-composite coatings. The coatings were heat treated at 200, 400, 600 and 700 oC and their chemical and physical properties were investigated and it was found that 400 oC was the optimum temperature for the heat treatment of the coatings. The micro-hardness test of coatings showed that t...

Artificial neural networks have emerged as a good candidate to mathematical wear models, due to their capabilities of handling nonlinear behavior, learning from experimental data and generalization. In the present work the potential of using neural networks for the prediction of abrasive wear properties of unfilled and graphite filled carbon fabric reinforced epoxy composite under various testi...

abstract this work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (dss). dss sintered composites of different volume percent (% vol) of partially stabilized zirconia (psz) was developed using powder metallurgy (pm) technique. electrochemical behaviour was studied at room temperature, using open circuit potential and potentiodynamic ...

In this study, the synergistic effects of abrasion and corrosion on UNS S30403, S31603 and S32760 stainless steels have been investigated using micro-abrasion test rig. The stainless steel samples have been studied under both pure abrasion (PA) and abrasion–corrosion (AC) conditions imulated by using silicon carbide based slurries in either distilled water or 3.5% sodium chloride solutions. Tes...

As the turbine industries need to manufacture turbine blades made of martensitic stainless steel AISI 420 with high toughness and wear resistance, local laser hardening has become more and more important. In this research, surface of the samples was initially hardened by high-power pulsed laser beam; then, optimum parameters of hardening were calculated and wear resistance of surface hardened s...

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral indus...

The behavior of different materials under macrotribological and nanotribological conditions has been compared. The materials, hydrogenated amorphous diamondlike carbon, highly ordered pyrolitic graphite, and mica, were submitted to a fretting test ~macrotribological behavior! and a combined atomic force microscopy/lateral force microscopy ~AFM/LFM! ~nanotribological behavior!. The coefficient o...
