When tungsten arc was used to melt an aluminum plate placed on a niobium block, the niobium surface was also melted and a melt pool of an Al-Nb binary alloy was formed on the niobium block. The melt pool solidified into niobium aluminides on the surface of the niobium block, forming a thick NbAl3 layer on the top surface of the coating layer. When an Al-Si alloy plate was used instead of the aluminum plate, a niobium aluminosilicide layer was formed on the niobium block.日本金属学会2004-09jpnjournal articleVoRhttp://hdl.handle.net/2115/75804https://doi.org/10.2320/jinstmet.68.7640021-4876AN00062446日本金属学会誌Journal of the Japan Institute of Metals689764768https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/75804/1/J.%20Jpn%20Inst.%20Metal%2068%289%29%20764.pdfapplication/pdf936.49 KB2004-09
