| Abstract: |
| Objective To discuss the study on relationships between the process of filler and paints decentralization and the film formation of paints, as well as the thermal protection and environment adaptability of the coating. Methods The applied paint was dispersed with different techniques, and then sprayed on steel, titanium and aluminum alloy substrates. The physical properties,thermal protective performance and environmental adaptability of the coating were compared and analyzed. Results The results showed that the degree of fineness of the effectively dispersed coating could reach 60 ~ 70 滋m. Ablation experiments and air-equipped laboratory test results verified that grinding and dispersion helped reduce stress, increase the coating ' s environmental adaptability, prolong the service life of the coating and improve the thermal protective performance. Conclusion The coating with full dispersion had the best appearance, performance and service life. |
