Industrial development brings with it the need for new materials every day. When it comes to
obtaining more than one feature together, composite materials are at the forefront of the material
groups. In composite materials, the main matrix and reinforcement element are defined and known
according to the material group and the morphology of the reinforcement elements. Electroless nickel
plating process is the chemical coating of nickel and its alloys on metal surfaces without using electric
current by the immersion method. This process is also preferred in many areas in industrial
applications for improving surface wear resistance of metallic and ceramic powders. These metallic
and ceramic powders are used for reinforcement to production of nickel base composite in this study.
For this purpose Ni coated (1.66% BN ceramic + 31.65% Astaloy-CrM metallic) + %66,67Ni nickel
powders were shaped circularly in uniaxial cold press. These samples are sintered in conventional
furnace with argon atmosphere at the temperature of 1000, 1100, 1200, 1300 and 1400 °C for two
hours. The mechanical properties of Ni based electroless Ni plated ceramic and metallic powders
reinforced composite samples were determined. In addition, the metallographic evaluation was carried
out by XRD analysis and SEM (Scanning Electron Microscope) on the samples. Consequently, the
highest density and hardness is obtained composite made from (1,66%BN + 31,65%Astaloy-CrM) +
66,67%Ni powders, It was sintered at temperature of 1400°C for two hour in tube furnace.
