The effect of counterface roughness on tribological properties of 10%nano-SiO2 reinforced polyamide composite was studied under dry friction on MM-200 wear tester.

The dry sliding friction and wear behavior of carbon fiber reinforced polyamide 1010 based composites in sliding against AISI1045 steel counterpart was investigated with a pin on disc test rig, with an emphasis on exploring the effect of the counterpart surface roughness on the tribological behavior of the composites.

Effect factors analysis of surface roughness of bearing ring groove;

Effects of Electromagnetic Field on Surface Roughness of High-activity TiAl Alloys;

The roll grinding and it's quantity of surface include precision,roughness of surface and mechanical capability.

The influences of cutting speed on cutting forces,cutting tempera-ture,roughness of surface,surface microstructure,and tool wear have been studied by the experiments.

The result shows that, due to the roughness of surface, the measured interface stress(f′) is always smaller than the actual one(f).

Research on improving surface roughness degree of metal parts;

With a precision instrument for surface roughness degree, the paper measures the surface roughness degree of the bamboo treated with "hot-in and hot-out" and "cold-in and cold-out" process and the bamboo in the nature condition, analyzes and treats the measuring results with mathematics methods.
