Study on Erosion Wear Property of Nickel-Chromium Cast Iron

Abstract:

The influences of the impact angle and the corrosive agent acidity on low-chromium and nickel contained cast iron were studied in the behavior of erosion wear. The wear rule was summarized and the mechanics of the erosion wear behavior were analyzed in this thesis. Erosion wear experiments were carried on MCF-30 erosion test machine, and then the structure and surface morphology of the samples were analyzed by Scanning Electron Microscopy (SEM). The results showed that the alloy carbide (Fe, Cr)3C was generated by a kind of reticulate distribution in the matrix after oil quench at 960°C and temper at 250°C. The continuous and homogeneous distribution, just like the skeleton of the material, enhanced the wear resistance. The shape of erosion wear curve was M at different impact angles. The biggest wear rate occurred at a 60-degree impact angle. The erosion wear property was greatly affected by the strong acid, but it can be ignored when pH3.
