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.

The silica surfaces polished with ion beam of 400ev energy and 100mA density in 35°incident angle for 2hrs was found to have a roughness less than 0.5nm . The SFM was also used to measure the surfaces to be bonded by SAB method and the deformations of the surfaces during contact each other. The micro roughness of the surfaces was found to produce great effect on the SAB strength. The rougher the surfaces are, the weaker the bonding forms.

本文首先将原子力显微镜应用于一种新的超光滑表面离子束抛光的工艺研究，搞清了表面纳米级微观形貌与离子束抛光参数之间的关系，在离子能量为400V、束流密度为100mA和入射角为40°时，经过两个小时以上的抛光，硅（111）表面微观形貌在1μm×1μm的范围内从抛光前的5nm下降到0.4nm。
