| Manufacturing of Corrosion Resistant Coatings Using Laser Assisted Thermal Spraying | ||
| Mr. Jyrki Suutala, Prof. Petri Vuoristo and Mr. Jari Tuominen, Material Science/Laser Application Laboratory, Tampere University of Technology, Korkeakoulunkatu 6, Tampere, 33720, Finland In the present study surface engineering related to simultaneously thermally sprayed and laser melted corrosion resistant coatings has been carried out. A 6 kW high power diode laser and a flame spray gun were used to construct the laser assisted thermal spraying system. The main aims of the study were to find out the optimal processing parameters and materials to create dense corrosion resistant coatings on steels and aluminium alloys with high processing speeds. The corrosion resistance of the manufactured coatings was measured and the microstructure characterized using optical and scanning electron microscopy. | ||
