【Abstract】 The dry friction and wear behavior of the flame spray coating of nylon 1010/ graphite composite were studied by means of uniform design method, wear-test machine and SEM. The statistics of regression analysis of the test results were made by using software SPSS 11.0, resulted in a numeral model of the relationship of the dry friction coefficient and wear mass loss with the PV volume. The results showed when the test velocity was 0.39～0.90 m/s, test loading 100～350 N, the friction coefficient was 0.395～0.419; when the test time was within 20 min, the wear mass loss was 3.0～14.5 mg, both of them were better than those of pure nylon. The wear mechanisms of the coating wear explained in terms of fatigue tearing and adhesive abrasion.更多还原
