Anticorrosion property Study on the hard Chrome plating Layer of hydraulic Cylinder Rod

摘要

The hydraulic cylinder is the essential component in the construction machinery, and the quality and safety of construction machinery products depends on its performance. As the main part of the hydraulic cylinder rod, the quality and reliability are the key indicators of the hydraulic cylinder. In this paper, the hard chrome plating layer of hydraulic cylinder rod was tested by metallographic analysis, surface morphology observation, hardness test, corrosion resistance experiment, in order to evaluate the anticorrosion, economy and technology of the electroplating technology, and discuss the anticorrosion mechanism, so the experimental and theoretical basis will be provided in the field of production. The contribution will be made by improving the corrosion resistance and wear resistance, increasing the operational reliability, extendeding service life of the hydraulic cylinder rod.
