The morphological analysis and chemical characterization of the worn surfaces via scanning electron microscopy, laser scanning microscope, and X-ray photoelectron spectroscopy reveal that under titrimetric water lubrication, the hBN in Si3N4-hBN spalled off during the wearing tests and the spalled pits formed on the wearing surface of Si3N4-hBN, and then the debris dropped into the pits to react with water, thus a tribochemical film formed on the wearing surface. The formation of the tribochemical film facilitated smoothing the surfaces of Si3N4-hBN and Si3N4 to create a fine lubrication environment.

在滴定法水润滑条件下，磨屑不易被水带走，当Si3N4-hBN与Si3N4配副摩擦时，由于Si3N4-hBN摩擦面上hBN偏聚区域发生脆性断裂和剥落而形成剥落坑，磨屑在剥落坑中堆积并氧化、水解，反应产物富集于剥落坑中，进而在摩擦表面形成含B2O3和SiO2的摩擦化学反应膜，从而保护了Si3N4-hBN和Si3N4摩擦面，使其变得光滑，为发生流体润滑提供了条件。

The dosage is determined by pH control approach, which does not require a routine jar test. This method can simultaneously determine the optimal pH and economical dosage for oxide-CMP wastewater. The coagulant can be added directly into the raw water without the pH adjusting at first. According to this method, the coagulant acts like a titrant and the pH of the oxide-CMP wastewater is monitored. The optimal dosage is the one that corresponds to a specific pH.

本论文主要以「pH控制法」来决定线上加药剂量值，其与传统瓶杯试验不同的是，其加药逻辑可直接对线上加药进行控制且毋须定期确认参数。pH控制法视混凝剂为酸滴定药剂，直接对进流之氧化层研磨废水进行加药，及至特定pH时，加药停止，此时之加药量即为电性中和去稳之控制点，远较过量加药法经济。
