| Abstract: | The technique and agent composition of powder rare earth-boronitriding under A1 temperature are re-searched.The structure,depth and the surface hardness of penetrating layer are also investigated. The wear resistanceand corrosion resistance of the layer are compared with the steel matrix.The results show that functional layer can beobtained with rare earth-boronitriding under A1 temperature the layer has very highe hardness ,Wear resistance and cor-rosion resistance. |
