Abstract:
A layer of matrix powder is deposited within a mold opening. A layer of super-abrasive particles is then deposited over the matrix powder layer. The super-abrasive particles have a non-random distribution, such as being positioned at locations set by a regular and repeating distribution pattern. A layer of matrix powder is then deposited over the super-abrasive particles. The particle and matrix powder layer deposition process steps are repeated to produce a cell having alternating layers of matrix powder and non-randomly distributed super-abrasive particles. The cell is then fused, for example using an infiltration, hot isostatic pressing or sintering process, to produce an impregnated structure. A working surface of the impregnated structure that is oriented non-parallel (and, in particular, perpendicular) to the super-abrasive particle layers is used as an abrading surface for a tool.
