英文摘要：

The mechanical properties of three kinds of coatings manufactured by chemical plating on the titanium materi- al were investigated by nanoindentation technique. Firstly, its mechanical responses （hardness and modulus） were obtained by changing the peak load. And the effect of peak load on nanoindentation measurement was discussed. It was found that, the caculated modulus and hardness of the coatings responds were more sensitively to the peak load; the results gradually decreased as the peak load increases, and the reducing trend is non-linear; the wear-resistant coating with nanoparticles has the best ability to resist deformation, and it can be used as an anti-fretting coating. This investigation established the founda- tion to scientificly evaluate the mechanical properties of coating materials.
