摘要：

A mechanism for abrasive wear resulting from slow flows of concentrated hard particle suspensions is described. The key to this mechanism is the development of a dispersive particle-phase pressure which is shown to lead to particle contacts with the surfaces bounding the flow. Analytical descriptions of the development of an abrasive traction are compared to finite element simulations. These analytical descriptions are then used to calculate measures of wear efficiency for the abrasive flow machining (AFM) process. (C) 1998 Elsevier Science S.A. All rights reserved.
