The effects of surface modification was evaluated by using the methods of corrosion tests, interfacial contact resistance measurement and XPS analysis.

05 mol/L H2SO4 +2 ×10-6 F- at 25 ℃ and 70 ℃ by electrochemical method, and interfacial contact resistances before and after electrochemical corrosion were evaluated.

Corrosion behavior of an austenitic stainless steel was investigated in H2SO4 + 2 mg/L F- solution simulated aggressive PEMFC environment by using electrochemical method, and the interfacial contact resistance was measured between passive film and carbon paper after polarization.

A DC surface contacted resistance measurement system was developed according to the characteristic of DC surface contacted resistance of metal material.

Study on Au-CdZnTe contact interface deposited by different process;

When the incidence wave is strong enough, the contact interface will separate or slide on local area, which is harmful to the safety of the structure.

Reflection and refraction of an elastic pulse at a frictional contact interface between two anisotropic media is studied theoretically in this paper.

A simplified potential model of contact surfaces,which is based on the strong volume-dependent characteristic of metal,is established to calculate the static friction force and the coefficient of two flat surfaces made of the same metal and to explain the origin of static friction force.
