摘要
采用磁控溅射技术在淬火态Cr12MoV表面制备SiC/TiN、SiC/TiB2-TiN薄膜(SiC为中间层),研究TiN、TiB2-TiN薄膜的组织结构和摩擦磨损性能。结果表明,SiC薄膜与基材和TiN、TiB2-TiN薄膜间都具有明显的且呈梯度的元素扩散,界面结合良好。在水润滑条件下与钢球对摩时(载荷0.5 N,时间0.5 h),TiN薄膜、TiB2-TiN薄膜具有良好摩擦磨损性能,其平均摩擦因数分别为0.33、0.31,低于淬火态Cr12MoV的0.45,磨损速率分别为2.0×10-8和1.5×10-8mm3/(N.m),低于淬火态Cr12MoV的8.66×10-7mm3/(N.m),其中在水润滑条件下TiB2-TiN薄膜比TiN薄膜具有更好的摩擦磨损性能。
Both SiC/TiN bilayer films and SiC/TiB2-TiN bilayer films(SiC film as interlayer)were deposited on quenched Cr12MoV steel substrate through magnetron sputtering technology,and the microstructure and the friction and wear properties of TiN film and TiB2-TiN film were investigated.The results show that all the interface among substrates,SiC films and TiB2-TiN(TiN)films show good bonding,with large and gradual element diffusions.TiN film and TiB2-TiN film have good friction and wear properties,when sliding against steel ball under water lubrication condition at 0.5 N load for 0.5 h wear duration,the mean friction coefficients of TiN films and TiB2-TiN films are 0.33 and 0.31,respectively,while the specific wear rate are 2.0×10-8 and 1.5×10-8 mm3/(N·m),respectively,which are lower than these of quenched Cr12MoV steel(0.45 and 8.66×10-7 mm3/(N·m),respectively).The friction and wear properties of TiB2-TiN films are better than those of TiN films.
