EIectroIess nickeI - phosphorus - aIuminum oxide composite deposits were prepared by the addi- tion of aIuminum oxide particIes in eIectroIess nickeI - phosphorus pIating bath . The effect of bath components and pIating parameters on pIating rate of nickeI - phosphorus - aIuminum oxide composite deposits was studied， microstructure and properties of nickeI - phosphorus - aIuminum composite deposits were compared to that of nickeI - phosphorus deposits . The resuIts show that nickeI - phosphorus aIIoy deposits are greatIy improved in microhardness and corrosion resistance by codeposition proper amount of aIuminum oxide particIes . ： ； Keywords nickeI - phosphorus - aIuminum oxide eIectroIess composite
