化学机械抛光是用化学药品配制成的化学抛光剂,与转动着的磨盘(表面是海军呢)作用下,而得到的金相观察的表面。这种化学抛光剂是用草酸3.5克、30％的双氧水10.5毫升、比重1.84的硫酸5毫升,然后加蒸馏水700毫升而配制成的。用手拿棉花蘸配制后的化学抛光剂,在经砂输和经0、01号砂纸后,进行擦拭1至4分钟,此法经改进后,将要磨的金相样经粒度为60或80的砂轮打平后,便可进行用化学机械抛光法抛光。其方法是:将配制好的化学抛光剂首先倒在一般用来作为最后抛光的抛光盘上,而后进行金相样的磨制,经一段时间后,则可用肉眼观察被磨面的情况,直到不见磨痕时为止。如果在金相样被磨面上出现像电介抛光时出现的波纹,即磨平了。应边磨边
Chemical mechanical polishing is the chemical polishing agent formulated with chemicals, and rotating the surface of the disc (the surface is the Navy it), and the resulting metallographic observation. This chemical polishing agent is prepared with 3.5 grams of oxalic acid, 10.5 ml of 30% hydrogen peroxide, 5 ml of sulfuric acid with a specific gravity of 1.84, and then 700 ml of distilled water. After the preparation of cotton polish by hand, the chemical polishing agent, after the sand is transported and the No. 0,01 sandpaper, wipe 1 to 4 minutes, this method is improved, the metal to be ground through the particle size of 60 or 80 After grinding the wheel flat, you can use chemical mechanical polishing polishing. The method is as follows: the prepared chemical polishing agent is poured onto the polishing disc which is generally used as the last polishing, and then the gold-like grinding is carried out. After a period of time, the polished surface can be visually observed until Not seen when worn. If in the same kind of gold-like was grinding surface appears like dielectric polishing ripple, that is polished. Should be edging
