Laser cladding of Inconel 690 on Inconel 600 superalloy for corrosion protection in nuclear applications

Numerical study on the effect of pressure and nozzle dimension on particle distribution and velocity in laser cladding under vacuum base on CFD

“…It has been widely used in many practical applications such as metallic coating, component repair, and 3D rapid prototyping [1][2][3]. The LC needs orientation in wide range of technological regimes, search of optimal energy characteristics of laser radiation (scanning speed, laser power, impulse duration, and frequency) and parameters of particle flux (powder feed rate, particle concentration and size), physical properties, chemical and fraction composition of powder.…”

Assessment of laser cladding as an option for repairing/enhancing rails

“…Currently laser cladding is used in the oil and gas [3,4], mining [5,6], nuclear [7,8] and security industries. Components in these industries, particularly mining, are subject to very aggressive operating conditions which lead to high wear rates.…”

Potentiostatic Oxide Growth Kinetics on Ni-Cr and Co-Cr Alloys: Potential and pH Dependences

“…Nevertheless, there still exists some controversy over the type of oxide that can be formed, the mechanism of oxide formation and growth, and the effect of the oxide film on corrosion kinetics of these alloys. This may have arisen due to the role of the different aqueous redox environments and mass transport conditions in those studies [13][14][15][16][17][18][19][20][21]. The challenge in fully understanding corrosion kinetics is linked to understanding the roles that elements of the solution environment (pH, temperature, ionic strength and the chemical and redox activities of aqueous species) play in the corrosion process for a given alloy.…”
