| 中文摘要: |
| N80钢在硫化氢和酸性介质中的腐蚀是非常严重的，为了提高它的抗腐蚀性，采用表面处理的方法。在本研究中，主要利用氧．乙炔火焰喷涂技术，在基体材料表面喷涂N120合金粉末制备涂层，然后通过液相腐蚀试验的方法，在相同的试验条件下，比较低碳钢N80和Ni20火焰喷涂层的耐酸性和硫化氢腐蚀性能，利用扫描电镜分析涂层的横断面组织结构，利用X射线衍射分析涂层的腐蚀产物。腐蚀试验的结果表明：氧一乙炔火焰喷涂Ni20合金涂层的耐腐蚀性能优于低碳钢N80，但是这种涂层孔隙率高，防腐蚀效果差。 |
| 英文摘要: |
| N80 steel is eroded very seriously in the solution of hydrogen sulfide and acid. The surface treatment technology was used to improve its anticorrosion. Ni20 alloys coating was prepared on the N80 steel substrate by utilize oxygen acetylene flare sprayed, then use the way of solution corrosion, the anticorrosion of N80 mild steel and oxygen acetylene flare sprayed Ni20 alloy coating were compared under the same experiment condition. The structure of alloy coating was observed by scanning electron microscopy ( SEM) and the effect of corrosion process was assessed by X-ray diffraction technique. The experiment result shows that the anticorrosion of coating is better than that of N80 mild steel, but Ni20 coatings anticorrosion effect is bad because of rate of core. |
