本文介绍了一种新的摩擦学性能测量装置。在此基础上，设计了一种改进的电唱机唱头，使唱头以30 Hz的频率、8-200 μm的振幅作平行于表面的正弦振动。施加的触针负载为0至1 N。当触针被压向表面时，在盒中产生反映表面的摩擦特性的电压信号。随着载荷的增加，对信号的分析产生摩擦系数。当载荷足够高时，基底上的表面或涂层破裂，并且拾取断裂和所得粗糙度的信号。MgO涂覆的玻璃基材的摩擦系数为0.26。在剪切应力下，Ag、Al、MgO和TiN膜在玻璃基底上的粘附力分别为0.7、1.2、1.7和3.3GPa。
A new apparatus is described which enables the tribological properties of a surface to be measured. A modified cartridge of the record player is driven to swing sinusoidally in parallel to the surface at a frequency of 30 Hz with an amplitude of 8–200 μm. The stylus load is applied from 0 to 1 N. As the stylus is pressed to the surface, a voltage signal which reflects the frictional properties of the surface is generated in the cartridge. The analysis of the signal with the increase of the load yields the coefficient of friction. When the load is high enough, the surface or the coating on the substrate is broken and the signal of both the fracture and the resultant roughness is picked up. The coefficient of friction for an MgO coated glass substrate was 0.26. The adhesion forces of Ag, Al, MgO, and TiN films on glass substrates were 0.7, 1.2, 1.7, and 3.3 GPa in shear stress, respectively.
