| 利用多功能摩擦磨损Plint TE-92试验机对镍基高温合金GH4169、F6NM和A不锈钢以不同配副方式组成的4组摩擦副在不同载荷和转速下的摩擦系数进行研究。研究结果表明，F6NM/F6NM、F6NM/A不锈钢摩擦副的摩擦系数随载荷增加而减小，随转速增加先减小后增大；GH4169/F6NM摩擦副的摩擦系数随载荷、转速增加先减小后增大；GH4169/A不锈钢摩擦副的摩擦系数随载荷增加先增大后减小，随转速增加缓慢减小。随着载荷速度（PV）值的增加， GH4169/F6NM，F6NM/F6NM两组摩擦副的摩擦系数呈先减小后增大趋势，GH4169/A不锈钢和F6NM/A不锈钢两组摩擦副的摩擦系数呈逐渐减小趋势。 |

| Abstract: |
| The coefficient of friction (COF)of four friction pairs composed of nickel-based superalloys GH4169, F6NM and a stainless steel with different matching modes was studied by using the multi-function friction and wear test machine Plint TE-92 under different loads and rotational speeds.Research result indicates that the COF of F6NM/F6NM and F6NM/A stainless steel friction pairs decreases with the increase of the load, and decreases first and then increases with the increase of the speed.The COF of GH4169/F6NM friction pair decreases first and then increases with the increase of load and speed.The COF of GH4169/A stainless steel friction pair increases first and then decreases with the increase of load, and decreases slowly with the increase of rotational speed.With the increase of PV value, the COF of GH4169/F6NM and F6NM/F6NM friction pairs decreases first and then increases. While, the COF of GH4169/A stainless steel and F6NM/A stainless steel friction pairs decreases gradually. |
