摘 要：By means of the engine shelf test, the gas escape amount of bent axle box was measured before and after adding hydroxyl silicate mineral powder lubrication oil additives, and discovered that gas escape amount after self-repaired is obviously smaller than before, the average gas escape amount of each rotate speed descend 6.5 %. Watching friction surface with SEM, discovered that the part of net veins in the cylinder inner surface are smoothly patched. Analysis with energy spectroscopy, discovered that there are some changing of atom component. Proofed that through rub chemical reaction, hydroxyl silicate mineral powder lubrication oil additives can generate new substance layer on friction surface, and can increase cylinder inner surface bulk, thereby get the repaired effects.
