查询词典 scanning

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。
