摘      要：The tribological properties of the in-situ dendrite-reinforced metallic glass matrix composite（Ti42Zr22V14-Cu5Be17）prepared by copper mould casting were analyzed at different normal loads under the dry condition and *** results showed that the average value of the frictional coefficients and micro-hardness ascended with increasing the normal load,while the wear rate showed a trend of decline under the dry *** electrochemical test results showed that the surface of samples was pitting corroded in the *** matrices were corroded *** the dendrites were exposed,leading to the damage of the *** the frictional coefficients and wear rate of the composite in the rainwater were larger than those under the dry condition,primarily owing to the corrosion of chloride ions on the worn *** wear mechanisms of composites were mainly adhesive wear,accompanied by the abrasive wear under the dry condition and corrosive wear in the *** composites have higher wear resistance both under the dry condition and rainwater due to the lower wear rate.
