Paper Title:
Application of Multi-Layer Composite Membrane in Tricone Bit Bearing
  Abstract

Composite membranes of TiN, WC/C and TiAlN+WC are successfully prepared by means of magnetron sputtering. An analysis of the membranes’ hardness, surface topography and chemical composition indicates that the composite membrane have a greater hardness, and are compact in structure and uniform in texture. A abrasion test is conducted by applying the three membranes respectively to tricone bit bearings, and then a comparison made between them and non-membrane tricone bit bearing leads to the finding that tricone bit bearing with TiAlN+WC/C composite membrane has the highest abrasion resistance, with a dramatic increase of 30%~40%.
