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 lubrication system provides a constant flow of filtered oil to all moving parts of the engine.the system consists of an oil pan to store the oil,a pump to circulate it,a filter to remove solid abrasive particles,and an oil gauge or light in the driver's compartment for checking purposes.

As the most suitable. In the notation of this grease, we should be careful not to melt into the heat, it can not be used to add other lubricating grease in ways to reduce their consistency, the correct way is to inject oil gun, scraper or wipe your fingers into the bearing cavity.

在加注这种润滑脂时，要注意不能加热熔化注入，也不能采用向润滑脂内加其它润滑油的办法来降低其稠度，正确的注入方法是用油枪、刮刀或用手指抹入轴承腔内。
