提出了定量评价堆焊层抗剥离性能的指标“开裂氢浓度C_(dc)”。研究结果表明,在不同试验条件下,对同一批堆焊试块的剥离性能进行评价,所得到的C_(dc)值基本上为一常量。因此,可将C_(dc)作为定量评价的参量。这种评价方法还能将堆焊试块的试验结果与在役反应器堆焊层的剥离问题联系起来。
The quantitative index of crack resistance hydrogen densities (C_ (dc)) was proposed. The results show that under different test conditions, the same batch of welding test block peeling performance evaluation, the obtained C_ (dc) value is basically a constant. Therefore, C_ (dc) can be used as a parameter for quantitative evaluation. This method of evaluation also relates the test results of the build-up test block to the peel-off of the overlay in service.
