Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] A kind of laser melting three-dimensional molding method of the present invention makes iron-based amorphous sensor probe, comprises the following steps:
[0032] Step 1, preparation of alloy ingot: the chemical formula of iron-based amorphous alloy is Fe 36 co 36 Si 4 B 20 Nb 4 , converted from atomic percentage to mass percentage; use high-purity raw materials Fe, Co, Si, B, Nb, weigh each raw material according to the composition of the iron-based amorphous alloy, and then put each raw material into a high-temperature furnace prepared in advance , in the presence of protective gas, the alloy is repeatedly smelted at high temperature to prepare a master alloy ingot; wherein, the protective gas includes one or a mixture of argon, nitrogen, etc.; the purity of the protective gas requires a volume percentage greater than 98% ;
[0033] Step 2, using gas ato...
