摘要：

The effects of post-coating processing by means of flame, laser and vacuum furnace heating on the structure and erosive wear characteristics of flame and plasma spray coatings were studied. The results show that post-coating processing can modify the microstructure, reduce its porosity, increase its plasticity and toughness and improve the metallurgical bonding to the substrate. Therefore, the erosion resistence of these deposits is increased substantially and is even more significant when the erodent impact angle and impact velocity are higher. The mechanism of erosive wear has obviously changed from brittle to plastic erosion. The application of different spray methods and post-coating processing in terms of erosive wear was analysed and compared.
