Abstract: In order to increase the hardness,strength and wear resistance of the compound material,based on the in-situ synthesis self-propagation reaction induced by high energy laser,the NiAl composite material was prepared by synthesizing the reinforced metal-ceramic hard particles.Added 0.01,0.015 and 0.02(mass fraction w) of tungsten concentrate powder respectively,combined hypereutectic Ni85Al15 powder was pressed into three kinds of billets.After sintering,the results of the the X-ray diffraction(XRD),secanning electron microscope(SEM),hardness and wear resistance of the sintering alloy were obtained.The results show that when the tungsten concentrate powder is not added,the main product phase of the sintering alloy are NiAl,Ni3Al and Al2O3;while if the tungsten concentrate powder is added,the sintering alloy products will produce Ni4W and WO3 phase on the side.When the mass fraction of tungsten is 0.01,the relative density of the sintering alloy is the biggest,which is 5.84g/cm3;the porosity rate is the lowest,which is 0.13%;the hardness rate of the sintering alloy is the highest,which is 325.2HK;the wear rate is the lowest,which is 0.27mg/mm2.The results show that the powder of tungsten concentrate can increase the hardness and wear resistance of the material,the material has the best hardness and wear resistance when its mass fraction is 0.01.
