中文摘要	采用正交试验法研究了堆焊工艺对FeA l金属间化合物堆焊层成形质量的影响,通过极差分析和方差分析,评价了堆焊工艺参数对成形质量影响的显著程度,并对堆焊工艺参数进行了优化。结果表明,堆焊电流、堆焊速度与电流之间的交互作用对堆焊层成形的影响最显著,堆焊速度对堆焊层成形质量影响较小,而粉末涂敷厚度的影响程度最小。对于Fe∶A l(原子比)为1∶2的混合粉末而言,本试验条件下能够获得较好成形的堆焊工艺参数是电流130 A、堆焊速度0.9 mm/s、粉末涂敷厚度2 mm。; The influence of overlaying technology on the performance of FeAl intermetallic compound overlaying shaping was studied by orthogonal experiment,the extent of influence on the performance of overlaying shaping was evaluated through the range analysis and variance analysis,and the technologic parameters of the overlaying technology were optimized.The results show that the electric current,the interaction of overlaying velocity and electric current affect the performance of overlaying shaping significantly,while overlaying velocity has less influence on shaping and effect of the thickness of powder overlaying coating is the least.Under the experimental conditions and when Fe∶Al proportion is 1∶2(atom rate),the optimized parameters are as follows∶electric current is 130 A,overlaying velocity is 0.9mm/s,powder thickness is 2 mm.
