摘要
用ＩＡＳ－ ４ 图像分析系统定量地测定了高温合金激光表面熔铸Ｃｏ 基合金涂层添加不同稀土含量的组织中二次枝晶间距变化，并对其影响规律作了定性分析。
With IAS 4 Image Analysis System,the distances between secondary dendrites in the structures of Co based alloy coatings,laser surface melt cast on the high temperature alloys with different contents of rare earth,were determined.Qualitative analysis of the effect regularities was made.
