Abstract:

Article Preview

Electroless plating technology used to alleviate fretting damage of titanium alloy was studied, Ni-Tl-B coatings were prepared, process optimization was worked out by the orthogonal table, deposition rate and solution consumption per hour and the initial friction coefficient and the bearing cycles under a low friction coefficient were chose as the index to calculate the range according to the economical efficiency and the application of coating under the surface morphology analysis and the fretting friction coefficient test, optimum process was finally worked out. Surface morphology was analyzed by TM-1000 scanning electron microscope and the fretting friction coefficient was tested by the DELTALAB-NENE fretting wear tester. The results shows that the surface morphology of the Ni-Tl-B coating are all typical cell structure which will be slightly different when the process changes and the optimum Ni-Tl-B coating has outstanding fretting damage resistance.
