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.

A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.
