| 摘 要： | 为探讨压气机叶片损伤修复新工艺,采用CO2激光熔覆技术,在钛合金表面进行了激光熔覆Ti/Cr2O3复合涂层试验。通过分析各工艺参数对熔覆层质量的影响规律,优化参数组合。结果表明,激光功率为1.8 kW、扫描速度6 mm/s时,稀释率达到最小,为3.95%,得到连续、均匀、无裂纹和气孔的高质量熔覆层,实现了良好的冶金结合。显微硬度明显提高,最高可达1050 HV,平均约为基材的3倍。

| Abstract: | To research and development new technologies of compressor blade damage remanufacturing,an experiment of laser cladding Ti/Cr2O3 on titanium alloy surface by CO2 had been carried out.The effects of processing parameters on the cladding layer height,dilution rate and penetration into the substrate had been examined.It is found that the dilution rate reachs the lowest value(3.95 %) at the laser power of 1.8 kV and the scanning speed of 6 mm/s.A white narrow metallurgical bonding zone is formatted at interface... |
