Abstract
The present article deals with the surface topography during high speed grinding of particulate reinforced titanium matrix composites (PTMCs). Scanning electron microscopic images of the ground surface was analyzed. Combining the results presented in this paper, the following results could be summarized: (1) The reinforcing particles of PTMCs are removed by means of voids, pulled-out, fracture or crushed, and micro-cracks, which attributed to the plowing and shearing during high speed grinding. (2) The formation of the fracture pattern of PTMCs is formed due to the wear debris of the abrasion during high speed grinding.
