The effect of TiCl_3 on the S-N-B process by gas, microstructures and properties was studied. A optimum adding amount of TiCl_3 was screened and better microstructures and properties of S-N-B process in low temperature are obtained.

• 研究了TiCl_3对气体S-N-B共渗动力学过程、组织和性能的影响,筛选出实现低温560℃S-N-B共渗获得较好组织和性能的TiCl_3的最佳加入量;
