Tribological characteristics of nickel-aluminium bronze CuAl_(10)Ni_5Fe_4 against 30CrMnSiA steel after the prior corrosion treatment

摘要

The tribological characteristics of nickel-aluminium bronze CuAl_(10)Ni_5Fe_4 against 30CrMnSiA steel after the prior corrosion treatment was studied at the M2000A model wear tester. The wear rate of corroded specimen was less than uncorroded specimen at the early stage of prior corrosion treatment, while the wear resistances deteriorated and the average friction coefficient slightly declined with the extension of prior corrosion period. The tests of CuAl_(10)Ni_5Fe_4 sliding bearing at PLS-100 swing tribometer were used to validate the results. The wear resistances of CuAl_(10)Ni_5Fe_4 sliding bearing increased slightly after a short period of prior corrosion, and the average friction coefficient decreased slightly after a long term of prior corrosion. A suitable period of prior corrosion treatment can enhance the wear resistance performance of CuAl_(10)Ni_5Fe_4 bearing. The tribological characteristics of CuAl_(10)Ni_5Fe_4 sliding bearing tested by PLS-100 rack swing tribometer are consistent with the conclusions of the tests at M2000A model wear tester.
