This paper provides an overview of the commonly used processes and equipment for laser cladding, including pre-set powder feeding, simultaneous wire feeding coaxial cladding nozzles. By comparing above related nozzles, coating characteristics are summarized selection appropriate methods in different working environments. Meanwhile, morphology properties clad layers shaft parts processed with pr...

Contact between the outer surface of a fuel pellet and the inner surface of the fuel rod cladding can result in several kinds of undesirable behavior. As the pellet swells outward and the cladding creeps down, large stresses are generated in both the pellet and the cladding. This contact may exacerbate chemical degradation of the cladding and the stress may enable rapid propagation of cracks. B...

High-manganese steel (HMnS) coating was prepared using laser wire feeding cladding technology. Erosion damage behavior and erosion rate of both the HMnS substrate were investigated at room temperature an testing machine. SEM/EDS, XRD, EPMA, microhardness analyses used to characterize cross sections matrix, as well morphology, phase composition, eroded surface. The orientation characteristics, g...

Aiming at the difficulty of temperature control in laser cladding process high-temperature nickel-based alloys, influence parameters on molten pool, and quality layer were explored. Firstly, through analysis finite element method, Inconel718 single-pass model was established surface 45 steel by using parametric language life–death technology, different power scanning speed pool center explored,...
