A TiN and TiN·Ti2Cu reinforced copper matrix composite layer was cladded onto a T3 copper substrate to improve the anti-wear performance of copper products by means of the nitrogen-shielded gas tungsten arc cladding method (N2-GTAC). Better than the traditional preparation method of TiN, the TiN particles in the cladding layer were in situ generated using N atoms of shielding gas and Ti atoms o...

Stress in laser cladding coating is an important factor affecting the safe operation of remanufacturing components. Ultrasonic testing has become a popular approach in the nondestructive evaluation of stress, because it has the advantages of safety, nondestructiveness, and online detection. This paper provides a review of ultrasonic testing for stress in remanufacturing laser cladding coating. ...

This paper numerically and experimentally investigates and demonstrates the design of an optofluidic in -plane bi-concave lens to perform both light focusing and diverging using the combined effect of pressure driven flow and electroosmosis. The concave lens is formed in a rectangular chamber with liquid core liquid cladding (L) configuration. Under constant flowrates, the performance of the le...

Using the Condon model to describe the dispersive behavior of optically active media, we analyze two different classes of waves in chiral optical fibers: surface and semileaky modes. Only when the cladding is chiral, semileaky modes do exist; accordingly, optical fibers with either chiral or achiral cores, but always with a chiral cladding, are considered. Two fundamental modes, corresponding t...

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 ...

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...
