Effect of Compositions of Penetrating Agents on the Microstructure of Tungsten-Chromium Surface Composite

Abstract:

Influence of the composition of cast penetration agents on the microstructure of Tungsten-Chromium surface composite layer was researched by conventional cast penetration process with main cast penetration agents of WC and high carbon ferro-chrome. The result is shown that a certain thickness composite layer metallurgical bonding with matrix is formed on the surface of ZG230-450 cast under the condition of experiment. The relative quantity of chrome carbide and tungsten carbide in surface composite layer changes with the increase of WC and the shape of tungsten carbide changes from discontinuous reticulation into sunflower and then into banding shape with the increase of WC and high carbon ferro-chrome.
