Sulfide layer was made on the surface of high speed steel (W6Mo5Cr4V2) by means of low temperature ion sulfurization. The tribological properties of the sulfide layer under dry sliding were investigated on an MM 200 friction and wear test rig. An atomic force microscope and a scanning electron microscope equipped with an energy dispersive spectrometer attachment were adopted to analyze the morphologies and compositions of the original and worn surfaces of the sulfide layer. The phase structure of the sulfide layer was determined by X ray diffraction.

In an ultrahigh vacuum chamber with a base pressure of 1 x 10-10 torr, we have used Low Energy Electron Diffraction and Temperature Programmed Auger to study the effect of adsorbates on the surface structure of Nb(111). That is, in O/Nb(111) systems, we observe the structure of the surface with LEED to see if any surface reconstruction occurs after annealing and analyze the structure.
