摘要
以Ar+10%H2(体积分数计)、H2及N2为载气,采用射频PCVD技术在40Cr钢表面制备了BN膜;对沉积BN膜进行了FTIR、TEM和SEM等分析;并对不同载气下膜与基体的结合力、膜层残余应力、硬度及耐磨性进行了比较.结果表明,BN膜中c-BN含量分别为58.1%、27.7%和27.4%,膜厚分别为4.6μm、2.0μm和3.3μm.
Boron nitride (BN) films were deposited by
plasma assisted CVD technique, using nitrogen (N 2), hydrogen (H 2) or vol. 10% H 2 diluted
in argon (Ar) as carrier gas. It was found by FTIR and SEM analyses that of the three carrier
gases, the c BN content was the highest for Ar + 10% H 2. The deposition rate was very low
with H 2 carrier gas. The bonding strength of the film determined by indentation test was the
lowest with N 2 carrier gas. TEM analysis indicates that the films composed were of
amorphous and cubic BN phases, with the size of c BN particles in the range of 20 ̄40 nm.
The residual stress, hardness, and antiwear properties of the films have also been investigated
and compared with eath other.
