The invention discloses a low-wear abrasive capable of improving corrosion resistance capability of the stainless steel surface and a preparation method of the low-wear abrasive and belongs to the technical field of grinding and polishing finish machining for stainless steel surface machining. The low-wear abrasive capable of improving the corrosion resistance capability of the stainless steel surface forms a quasicrystal and approximates and comprises components as follows: Al-(Li,Cu,Fe,Co,Cr,V,Mn,Ru,Re,Os), TiZrNi, (Zn/Cd)-Mg-(Y,Yb,Gd,Tb,Dy,Ho,Er,Sc) and Cd-(Ca,Y,Gd,Tb,Tm,Ho,Dy,Er,Yb), and the content of the quasicrystal and the approximates is larger than 50%. The abrasive is used for grinding and polishing the stainless steel surface and also can realize low-wear polishing and finish machining of stainless steel and rapidly improve the surface corrosion resistance capability.
