Analysis model and experimental research of dilution in laser induction hybrid cladding

  • Based on the analyses of induction heating temperature model and laser induction hybrid cladding energy function, the dilution expression was derived, which quantitatively reflect the relationship between dilution and hybrid cladding process parameters. The expression was proved by the laser induction hybrid cladding experiments. The results show that the dilution increases with the increase of laser power, while the dilution decreases with the increase of powder feeding rate and scanning speed. The dilution increases significantly with the increase of induction energy, when the other processing parameters are not changed. The dilution model is helpful to control the dilution in laser induction hybrid cladding. It can be used for optimizing the process parameters and quality control of cladding coatings.
