- 摘要:
- 为了提高身管钢表面的耐高温氧化性能，采用电弧离子镀层技术在身管钢表面沉积Cr涂层，研究了1 000 ℃时Cr涂层对身管钢的防护能力。利用纳米压痕仪、扫描电镜、X射线衍射仪和能量色散光谱仪对身管钢及Cr涂层的力学性能、微观形貌、物相组织和元素成分进行了表征分析。结果表明，当温度为1 000 ℃，身管钢的氧化物膜发生开裂、剥落、分层现象，Cr涂层表面形成致密的氧化膜，Cr涂层氧化膜的厚度远低于身管钢，Cr涂层的高温防护效果明显优于身管钢。
- Abstract:
- In order to improve the high-temperature oxidation resistance of the barrel steel surface, Cr coating was deposited on the surface of the barrel steel by arc ion plating technology, and the protective ability of the Cr coating on the barrel steel at 1 000 ℃ was investigated. The mechanical properties, micro-morphology, physical phase organization and elemental composition of the barrel steel and Cr coating were characterized and analyzed by using nanoindentation instrument, scanning electron microscope, X-ray diffraction instrument, and energy dispersion spectrometer. The results show that when the temperature is 1 000 ℃, the oxide film of barrel steel occurs cracking, peeling, delamination phenomenon, Cr coating surface to form a dense oxide film, Cr coating oxide film thickness is much lower than that of barrel steel, Cr coating of high temperature protection effect is significantly better than that of barrel steel
