通过对单－渗硼、硼－氮共渗．硼－氮复合渗、硼－锆共渗和硼－土共渗等方法所得到的铁－硼金属间化合物分别进行了硬度梯度，脆性和耐磨性试验。试验证明，无论是复合渗还是共渗，其渗层性能都优于单－渗硼层，其中以硼－稀土共渗渗层的性能最佳．在本文试验条件下，与单一渗硼层相比，共渗和复合渗渗层的脆断强度提高３０％～５４％，相对脆性降低４７％～１１６％，相对耐磨性提高３２％～１０９％．
Through the single - boronizing, boron - nitrogen permeation. Boron-nitrogen composite infiltration, boron-zirconia co-infiltration and boron-earth infiltration obtained by the iron-boron intermetallic compounds were hardness gradient, brittleness and wear resistance test. Experiments show that, both the composite seepage or co-permeation, the seepage performance is better than the single - boronized layer, which boron - rare earth infiltration layer performance best. Compared with the single boronizing layer, the brittle fracture strength of the co-infiltration and the composite infiltration layer are increased by 30% -54%, the relative brittleness is reduced by 47% -116% and the relative wear resistance is increased by 32%-109 %.
