Study On Wearbility FeB-Q235 And B₄C-QT500-7 Composition Material

With the development of human society,the development of science and technology brings us more convenient, quick, comfortable life. Since the second industrial revolution, the field after the rapid development of science and technology, and human's energy demand has increased dramatically, loss serious, the earth's environment has been damaged seriously. And the energy shortages and rising prices more scarce, and even serious influence economic serious global economy.As the most development prospects of energy, nuclear power would cost only a small amount of raw material to gain enormous amounts of energy, the advantage is obvious. Radiation material tremendous damage to the human body, and if save operation caused leaks, it will even devastating blow to type survival.As the most development prospects of energy, nuclear power would cost only a small amount of raw material to gain enormous amounts of energy, the advantage is obvious. In fact, it is gradually into the human production and life is increasingly becoming the mainstream of human consume energy. However, at the same time it's potential hazards are generally huge as well as advantages. Radiation material tremendous damage to the human body, and if save operation caused leaks, it will even devastating blow to type survival.In this context, born shielding materials research, in the current study, shielding materials because of its shield effectively BNCT performance of neutron radiation widely attention. China institute of nuclear power was proposed in high impact toughness of high boron content of shielding materials, therefore, experimental design with the way the suspended casting with boron particles, sc, join as steel) material, to obtain high performance and cost is low shielding materials. In the meantime, considering the boron particle high hardness, before joining the characteristics of steel) materials, just after hard particle materials for the composite matrix fortifies soft, working with ba type alloy - soft substrate distribution in the hard particles, such materials - mode the same whether also has good abrasion resistance, and make the material has a variety of functions?In order to explore the particles reinforced steel (iron) composites wear resistance, experimental design QT500-7 materials used as contrast material, to explore the method in suspension casting iron particles reinforced with boron, with Q235 composites and boron carbide particles reinforced QT500-7 composites, and the wear resistance of boron QT500-7 particles reinforced composites made normalizing the wear-resisting experiment, after grain size, discussed how to join the performance, matrix of composite material changes, the influence of abrasion resistance.Tests show that the two composites are much higher than the wear-resisting performance QT500-7 materials; FeB - the wear resistance of Q235 composite significantly better than QT500-7 ductile iron and B4C - QT500-7 composite materials; B4C - to QT500-7 composite study show that, using electroless nickel plating process after the carbonization boron ductile iron particles reinforced the wear-resisting performance is better than the particle matrix not nickel plating material, and the effect is not obvious grain size.
