Study On Surface Intensify Disposal And Abrasion Performance Of Locomotive Engine Piston Ring Groove

The abrasion between the locomotive engine piston ring groove and piston ring is one of the mostly abrasion in the firebox of locomotive engine. Because of the special position and configuration of the engine piston ring groove, research in intensify the attrition capability for this friction is infrequency. For this reason, attrition of surface engine piston ring groove is overstepping, and become the most important reason for the disabled of the piston. Face the status, the dissertation use surface quenching,salt bath nitriding, cathodic arc deposition build TiN membrane to improve the attrition capability of engine piston ring groove surface; Deal piston ring with the method of hydronium sulfuration, in purpose of choose the most efficiency way to ameliorate the attrition of engine piston ring groove surface. Studied as follows:1 .Add "mosheng" grain additive lubricating oil to the most important frictions in firebox of locomotive engine, experiment prove that this kind of lubricating oil does not exert obvious function for debase the attrition of the frictions.2. Dispose different samples in different surface intensify method, and then do friction experimentation with unsettled piston ring samples. through availability data like: friction factor,attrition quantity etc, confirm cathodic arc deposition build TiN membrane is the best method.3. Deal piston ring with the method of hydronium sulfuration, and then do friction experimentation with different samples of locomotive engine piston ring groove. Contrast in friction factor,attrition quantity, analyze the energy chart of abrasion surface, gain the particular date that the method of hydronium sulfuration to debase attrition.Through texts, cathodic arc deposition build TiN membrane is a availability way to improve the attrition capability of engine piston ring groove, additionally, dispose the piston ring with the method of hydronium sulfuration, could obvious debase the friction factor,attrition quantity, prolong the useful life of the locomotive engine.
