将超细钼粉同烧结坯打磨抛光,采用2.3g NaOH+2.6g K3[Fe (CN)6]+20ml蒸馏水混合制备的金相腐蚀液并对抛光后的钼试样进行腐蚀,腐蚀时间为90s,随后在Mx6Rt型金相显微镜下观测其金相组织。
Polish the ultrafine molybdenum powder with the sintered billet, and use a metallographic etching solution prepared by mixing 2.3g NaOH+2.6g K3[Fe (CN)6]+20ml distilled water to corrode the polished molybdenum sample. The corrosion time is 90s, and then observe its metallographic structure under the Mx6Rt type metallographic microscope.
