| Abstract |
The micro-pulse d.c. plasma system has been adopted to the paste boriding of steel to reduce the optimum process temperature. By using pulsed plasma, the most desirable microstructure and hardness are obtained at 700℃ which is about 100℃∼200℃ lower than that of typical gas boriding. The X-ray diffraction analysis shows that the tooth-shaped dendrite in the surface layer is mainly the mixture of FeB and Fe₂B. The composition of paste which determines the chemical potential of dissolved boron greatly influences the optimum process temperature and mechanical properties of boride layer. |
