Paper Title:
Properties of TiN Coating Prepared on 3Cr2W8V by Electron Beam Surface Alloying Process
  Abstract

TiN coating was deposited on 3Cr2W8V alloy by PVD and then processed with electron beam surface alloying process. The microstructure, microhardness, friction coefficient, amount of wear and corrosion resistance of electron beam treated specimens were investigated. It is shown that the electron beam treated specimens can improve the properties of material. The coating has an average microhardness of approximately HV800, the friction coefficient of electron beam irradiation treated specimens is considerably lower than that of TiN coating. When the electron beam irradiate times is appropriate, the roughness of surface will much lower, and it will achieve polishing effects. The corrosion behavior of the composite coating in 3.5% Nacl solution at room temperature was also determined using a potentiont state system. In comparion with the corrosion potential for 3Cr2W8V alloy, the corrosion potentials of TiN coating and electron beam treated specimen are increased respectively. The electron beam treated specimen has the lowest corrosion current density as well as the highest corrosion potential showing an improved corrosion resistance compared with 3Cr2W8V alloy.
