Ti10Fe5Si5Cr3Nb composite coatings were fabricated using laser cladding technique. Laser power was varied from 800W to 1200W while the scanning speed kept constant at 1.5 m/min. The microstructural analysis of samples conducted by optical microscope, X-ray diffractometer and electron microscope coupled with energy dispersive spectroscopy. Potentiodynamic polarization diamond indenter used study...

The cladding of a modern building is a critical, and expensive, specialist subsystem of the total building. This paper is concerned with modelling the supply chain processes within the building cladding sector of the UK construction industry. The modelling was conducted within the context of CIMclad, a research project involving a consortia of universities and industry that is seeking to move t...

In this Article dispersion characteristic of conventional optical waveguide with helical winding at core – cladding interface has been obtained. The model dispersion characteristics of optical waveguide with helical winding at core-cladding interface have been obtained for five different pitch angles. This paper includes dispersion characteristics of optical waveguide with helical winding, and ...

IN 625 is one of the most widely used nickel-based high-temperature alloys. However, unstable mechanical properties IN625 and difficulty processing complex parts have limited its wider application. This work fabricated coatings with Co/TiAl (1.25, 1.55, 1.85) on 304SS using laser melting deposition technology, excellent properties. The effects microstructure laser-cladded resulting been careful...

Steel, also known as iron alloy, is found 35% of the whole mass Earth. It in many applications due to its unique properties. Alloying elements provide backbone support for iron, improving mechanical, physical, chemical, and structural Failure steel chemical reaction i.e., corrosion, it unavoidable, but can be prolonged. Applications such marine have a salt corrosive environment. High-temperatur...

Corrosion is one of the important factors in equipment failures. Wall thinning can be used to evaluate corrosion conditions. However, most of equipments are coated with insulations in order to elevate the energy efficiency. Pulsed eddy current (PEC) testing technique can be used to measure wall thinning through insulation. But when the insulation outside is wrapped with galvanized steel, PEC si...

Zirconium-based alloys are widely used in the field of nuclear industry as cladding for nuclear fuel in power plants. In a pressurized water reactor (PWR), boric acid is added in the coolant for reactivity control. Lithium hydroxide is added to render the coolant slightly alkaline, which helps to inhibit corrosion product deposition on the fuel cladding and reduces the corrosion rate of structu...

Ni-based alloy powders with different contents of cobalt (Co) have been deposited on a 42CrMo steel substrate surface using a fiber laser. The effects of Co content on the microstructure, composition, hardness, and wear properties of the claddings were studied by scanning electron microscopy (SEM), an electron probe microanalyzer (EPMA), X-ray diffraction (XRD), a hardness tester, and a wear te...

Missing pellet surface (MPS) defects are local geometric defects in nuclear fuel pellets that result from pellet mishandling or manufacturing. The presence of MPS defects can cause clad stress concentrations that are substantial enough to produce through-wall cladding failure for certain combinations of fuel burnup, and reactor power level or power change. Consequently, the impact of potential ...

To improve the tribocorrosion performance of 316L stainless steel (SS), multi-layer (1, 2 and 3 layers) Fe-based alloy coatings were manufactured by laser cladding amorphous powder on SS, corrosive wear behavior was investigated against Alumina ball in Ringer's solution. With increase layer number, content body-centered cubic (BCC) phase increases, hardness also improved. The volume loss rate S...
