采用座滴法研究了Nd 2Fe 14 B与富Nd相的润湿性。制备的富钕合金锭成分为Nd 72.0Fe 26.1B 1.9（三元）和Nd 72 Fe 22.4Cu 3.7B 1.9（加铜）。将富Nd锭切割并置于抛光的Nd 2Fe 14 B板上并在炉中加热。在控制温度下，测量了Nd 2Fe 14 B板与富Nd锭之间的接触角作为润湿性的参数。对于添加Cu的样品，在所有温度范围内的接触角和接触角开始变化的温度都低于三元样品。这些结果表明Cu取代产生润湿性的改善。对两种富Nd铸锭的DTA测试表明，在低于熔点的温度下，接触角开始发生变化，这可能是由于Nd_2Fe_（14）B/富Nd界面的存在所致。
The wettability between Nd2Fe14B and Nd-rich phases has been investigated through the sessile drop method. The compositions of prepared Nd-rich ingots were Nd72.0Fe26.1B1.9 (ternary) and Nd72Fe22.4Cu3.7B1.9(Cu-added). Nd-rich ingots were cut and put on a polished Nd2Fe14B plate and heated in a furnace. Contact angles between Nd2Fe14B plate and Nd-rich ingots were measured as a parameter of wettability under controlled temperature. For the Cu added sample, both contact angles in all temperature range and temperatures when contact angle starts to change were lower than those for ternary sample. These results indicate Cu substitution yields improvement of wettability. DTA measurements for two Nd-rich ingots reveal that their contact angles starts to change at lower temperature than their melting points It is considered that those phenomena are derived from the existence of Nd2Fe14B/Nd-rich interface.
