The effect of laser cladding on the surface microstructure and corrosion properties of coated/uncoated specimens were investigated. Fe-based alloy coating was produced on 35CrMo steel by laser cladding. The phase composition, microstructure, interface element distribution, microhardness and corrosion resistance of the cladding coating were measured. The results show that the cladding layer is m...

The fatigue properties of ultrathin protective coatings on silicon thin films were investigated. The cohesive and delamination fatigue properties of 22 nm-thick atomic-layered-deposited (ALD) titania were characterized and compared to that of 25 nm-thick alumina. Both coatings were deposited at 200 °C. The fatigue rates are comparable at 30 °C, 50% relative humidity (RH) while they are one orde...

This paper reviews research carried out towards the development of a novel conductive coating for reinforced concrete structures in order to enable the application of electrochemical anti-corrosion treatments. The coating is composed of a hardened paste containing graphite powder and cement. The applied techniques were electrochemical chloride extraction (ECE), cathodic protection (CP), and cat...

The aim of the research is to improve composition cold BNR (bitumen-nairite rubber) by improving technical properties, technology anti-filtration and anti-corrosion materials using at repair hydraulic structures, as well development a method for predicting state reliability structures with sealing protective coating.

Hydroxyapatite/tannic acid coating (HA/TA) were prepared on AZ31 magnesium alloys (AZ31) via chemical conversion and biomimetic methods. The characterization and properties of the coating were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), corrosion testing, MC3T3-E1 cell proliferation assay, and MC3T3-E1 cell morphology o...

in this work, polypyrrole/ceo2 nanocomposite (nc) was synthesized in the presence of methylorange as a reactive self-degraded soft template. the field emission scanning electron microscopy(fesem) images indicate that the ceo2 nps have a nucleus effect and cause a homogenous ppycore–shell type morphology with an encapsulation of the ceo2 core by the ppy shell. the effect ofnc on acrylic waterbor...
