| 中文摘要: |
| 太阳能热发电中,熔融铝硅合金储能材料会对换热管造成一定的腐蚀,为了延长换热管的使用寿命,在其表面制备了C1,C2和C3三种涂层,并对三种涂层的抗热震性能、附着力和耐熔融铝硅合金腐蚀性能进行了研究。结果发现:三种涂层具有较好的抗热震性能和附着力,在经过1080h熔融铝硅合金腐蚀试验后发现,C3涂层具有最好的耐腐蚀能力,涂覆C3涂层的20G钢基体的腐蚀层厚度,相对于无涂层20G钢基体降低了93.69%。 |

| Molten Al-Si alloy phase change material would produce a certain corrosion to the heat exchange tube in solar thermal power generation integration system. C1, C2 and C3 protective coatings were prepared to enhance the life of 20G heat exchange tube. The properties of thermal shock resistance, adhesion and anti-corrosion of coatings were also studied. Results show that three coatings have good thermal shock resistant and adhesion properties, and C3 coating has the best capability of anti-corrosion after 1080h corrosion test. Compared with 20G steel substrate, the thickness of corrosion layer of 20G steel sprayed C3 coating drops 93.69%. |
