Ceramic metallographic chemical corrosion method
The invention discloses a metallographic chemical corrosion method for ceramics. The metallographic chemical corrosion method comprises the following steps: performing mirror polishing on the ceramics; and immersing the polished ceramic into a sodium hydroxide solution for corrosion, taking out the ceramic after corrosion is completed, placing the ceramic in air for oxidation, then immersing the ceramic into the sodium hydroxide solution again for corrosion, and taking out and cleaning the ceramic after corrosion is completed. The ceramic metallographic chemical corrosion method has the beneficial effects that the temperature and the time of the sodium hydroxide corrosion solution are controlled, and the temperature and the time supplement each other, so that the optimal corrosion effect is achieved. And moreover, the operation is simple, the effect is outstanding, and the metallographic structure corroded by the corrosion method disclosed by the invention is clearer and more visible than metallographic structures corroded by other electrolytic metallographic corrosion methods or other chemical methods.
本发明公开了一种陶瓷金相化学腐蚀方法，包括以下步骤：将陶瓷进行镜面抛光；将抛光后的陶瓷浸入氢氧化钠溶液中腐蚀，待腐蚀完毕，取出置于空气中氧化，然后再次浸入氢氧化钠溶液中腐蚀，待腐蚀完毕，取出、清理。本发明的有益效果为：本发明所述陶瓷金相化学腐蚀方法通过对氢氧化钠腐蚀溶液的温度和时间的把控，温度和时间相辅相成使腐蚀达到最佳效果。且操作简单，效果突出，采用本发明所述的腐蚀方法腐蚀的金相组织比其它的电解金相腐蚀或其它的化学方法金相腐蚀更清晰可见。
