研究激光粉末床熔融增材制造(Am)(又称直接金属激光烧结)技术制备的Ti6Al4V合金等离子体电解氧化(PEO)处理及其电化学行为。通过短时间(m合金和传统合金表面制备了3~10μm厚、含Ca和P的涂层。然后在改良的α-mEm溶液中,通过动电位极化曲线和电化学阻抗谱(EIS)评估了合金的电化学行为。与传统合金相比,Am合金中形成了细小的层片状α显微组织和层间小尺寸的β相颗粒,这促使了火花的产生,从而促进了PEO涂层的生长。闪速PEO涂层提高了传统合金和Am合金的耐腐蚀性,最薄的涂层(m)提供了高达3倍的保护。Am Ti6Al4V由于其高的晶界密度,易受局部缝隙腐蚀的影响。而即使短至35 s的闪速PEO处理也足以成功避免这种情况。

重力恢复和气候试验 GRACE（gravity recovery and climate experiment）卫星极大地提高了地球重力场的精度和分辨率，特别是中长波分量，联合卫星测高数据可获得全球海洋表面大尺度洋流循环。另外，新一代地球重力和海洋环流探测卫星 GOCE（gravity field and steady-state ocean circulation explorer）于2009年3月成功发射，采用卫星重力梯度测量原理，对重力场的高频部分非常敏感，使其高分辨率监测全球海洋循环成为可能。本文利用1～7年 GRACE 观测数据确定的重力场模型和18个月 GOCE 观测数据确定的地球重力场模型 GO CONS GCF 2 TIm R3，联合卫星测高确定的平均海面高模型 mSS CNES CLS 11，分别估计全球海洋表面地转流，并且与实测浮标数据结果进行比较。分析表明 GOCE 重力卫星确定的重力场模型具有更高的空间分辨率，能够确定高精度和高空间分辨率的全球海洋地转流，如墨西哥湾暖流的细节和特征，并且与实测浮标结果基本一致。而基于1～4年 GRACE 观测资料的模型不能很好估计全球地转流特征，基于7年 GRACE 观测资料的重力场模型 ITG-Grace2010s 确定的全球地转流的精度仍低于18个月 GOCE 观测数据确定的地球重力场模型 GO CONS GCF 2 TIm R3的结果，估计的全球地转流仍含有较大的噪声，不能很好地反应中小尺度地转流细节特征。并计算 ITG Grace2010s 和 GOCE TIm3的稳态海面地形和全球平均地转流的内符合精度，结果显示，在全球范围内，GOCE TIm3的稳态海面地形和全球平均地转流的精度都比 ITG Grace2010s 结果的精度有着很大的改善，其中 ITG Grace2010s 的稳态海面地形的精度为21．6 cm，而 GOCE TIm3的结果则为7．45 cm，ITG Grace2010s 的全球平均地转流的精度为40．7 cm/s，而 GOCE TIm3的结果则为19．6 cm/s。
