Friction behavior of laser cladding magnesium alloy against AISI 52100 steel [PDF]

, 2012
The use of magnesium alloys in engineering applications is becoming increasingly important as a relatively low density allows savings in energy consumption and therefore reduction in air pollution.

Electron Microscopy Characterization of Ni-Cr-B-Si-C Laser Deposited Coatings [PDF]

, 2013
During laser deposition of Ni-Cr-B-Si-C alloys with high amounts of Cr and B, various microstructures and phases can be generated from the same chemical composition that results in heterogeneous properties in the clad layer.

Laser-powder-material interactions in the laser cladding process [PDF]

Le Journal de Physique IV, 1994
In this paper we present briefly two possible approaches for modelling the laser cladding process. The first approach is 2D and consists in finding the shape of the molten pool given the fraction of the laser power which is available at the surface of the workpiece and given the amount of powder sticking to the molten pool.

Compact high-energy Q-switched cladding-pumped fiber laser with a tuning range over 40nm [PDF]

, 1999
We describe a compact Q-switched diode pumped double-clad ytterbium-doped fiber laser. The fiber laser was bidirectionally pumped by two laser diodes (2W of output power each) via two side-injecting pump-couplers.

Influence of laser shock peening on the joint surface strength of laser cladding repair of GH4169 superalloy component [PDF]

MATEC Web of Conferences
Laser cladding is an effective method to repair damaged aeroengine blades. However, the heat affected zone of laser cladding reduces the strength of the repaired component.

Numerical Simulations of the Influence on the Temperature Fields of Large-Sized Nd-Glass Slab with Designed Edge-Cladding Materials, Methods, and Structures

Photonics, 2022
The good cladding of a large-sized Nd-doped phosphate glass slab as a laser amplifier requires not only the amplified spontaneous emission and parasitic oscillation to be fully absorbed, to hold up the small signal gain coefficient of the Nd ions, but ...

Effects of Process Parameters on Microstructure and Properties of In-situ synthesized WC-reinforced Ni-based Cladding Layer

Materials Research
A novel tungsten carbide (WC)-reinforced nickel (Ni)-based laser cladding layer was prepared through an in-situ synthesis process. The mechanism of the effect of scanning rates and laser power on the microstructures, wear and corrosion resistance of in ...
