Abstract: The technique of aluminising on brass by powder plating method has been studied.The optimum technological conditions obtained were:temperature 600℃,time 3h and the constitute of coating agent aluminium powder 40%,NH₄Cl 2% and alumina powder 58%.After aluminising,The corrosion resistance of brass increases 1.8 times,the hardness increases 25.6% and the coating thickness is 50μm.The structure of coating layer of aluminium on brass from surface to interior obtained by X-ray diffraction analysis was:Cu_0.6108Al_0.3892→γ₂-Cu₉Al₄→α-CuZn(Al)→α-CuZn.
