Notizen:
The thermal sprayed coatings are widely used in waste incineration boilers and fossil fuel-firedboilers. However, the defects, such as porosity, cracks and unmelted particles, in these coatings aredetrimental to corrosion performance. In this study, the nickel based self fluxing alloy coating was fusedby YAG laser to improve hot corrosion resistance of the coating. Under appropriate laser parameters, thenonporous, crack-free coating was produced. Hot corrosion test, conducted in the presence of a mixed salt ofNa2SO4/NaCl/KCl at 550[removed info]Г[removed info]showed that the modified coating exhibited excellent corrosion resistancecompared with the as sprayed and gas fused coatings
