The Research Of That Mixing Ion Beam Treatment Improved The Tribology Capability Of Oil Allocating Pair Of Hydraulic Pump

The oil allocating pair of hydraulic pump of bar piston is the typical end face rubs pair, its tribology performance directly affect the work status and the service life of the hydraulic pump. Ion beam mixing is made to oil allocating pair movement test sample, convention quenching and tempering nitriding is made on spouse static (25Cr3MoA).The tribology and attritional contrast experiment is carried on under the simulation of industry and mining condition. This article has carried on the experiment and the research from the following several aspects:1st, B+B2O3 steam plates the membrane is carried on the surface of the oil allocating pair-movement test sample, then N~+ recoil pours is carried to the membrane and the substrate with the ion beam, thus so-called ion beam mix processing is implemented.Its goal is that the chemical composition and the organization structure of the membrane level will change, it improves the performance further, on the other hand, it will make the membrane level and the substrate sutures together and enhance the binding force of the membrane level.2nd, under the simulation of industry and mining condition, the tribology and the attrition contrast experiment is carried on.The tribology and attritional contrast experiment is carried on under the simulation of that the test sample which is dealt with the ion beam mix processing and the test sample which is not. It expect that the moving part which is dealt with the ion beam mix processing has the better tribology performance than the moving part which is not dealt with the ion beam mix processing.3rd, the superficial ingredient will be determined by the rests of Auger electron characteristic energy content, then the theoretical analysis of the enhancement of its tribology performance will be given.The elemental composition of the surface of the solid will be determined under the qualitative analysis of Auger electron characteristic energy content. Then it can analyze the enhancement of the friction performance of the test sample which is dealt with the mix processing by the surface chemistry ingredient which is obtained.
