Laser-powder-material interactions in the laser cladding process
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. The powder reaching the workpiece is assumed to melt instantaneously at...
متن کاملCr13Ni5Si2-Based Composite Coating on Copper Deposited Using Pulse Laser Induction Cladding
A Cr13Ni5Si2-based composite coating was successfully deposited on copper by pulse laser induction hybrid cladding (PLIC), and its high-temperature wear behavior was investigated. Temperature evolutions associated with crack behaviors in PLIC were analyzed and compared with pulse laser cladding (PLC) using the finite element method. The microstructure and present phases were analyzed using scan...
متن کاملTiC Reinforcement Composite Coating Produced Using Graphite of the Cast Iron by Laser Cladding
In this study, a TiC-reinforced composite coating was produced to improve the wear resistance of a pearlite matrix grey iron using a pre-placed Ti powder by laser cladding. Results of scanning electron microscopy (SEM), X-ray diffractometer (XRD), and energy dispersive X-ray spectroscopy (EDS) confirmed that the coating was composed of TiC particles and two kinds of α-Fe phase. The fine TiC par...
متن کاملSynthesis oF Fe-TiC Hard Coating From Ilmenite via Laser Cladding
The aim of this work was to synthesize TiC reinforced coating on carbon steel via reduction of ilmenite powder. A mixture of ilmenite and graphite was pre-placed on AISI 1020 steel surface. The effect of the addition of excess graphite amounts on the progress of synthesis of carbide particles was studied. The evolution of phases in different coatings was analysed via X-ray diffraction and scann...
متن کاملClosed Loop Control of 3d Laser Cladding
In this paper, a heat input closed-loop control system based on infrared image sensing for 3D laser cladding is introduced. A high frame-rate (up to 800 frames/s) camera is installed coaxially on the top of the laser-nozzle setup. Complete of the infrared images of the molten pool can be acquired with a short nozzle-substrate distance in different scanning directions, eliminating the noise from...
