进一步发展了摩擦系统品质因数的定义，与已知的定义不同，该定义不仅考虑了摩擦系统的几何尺寸、摩擦元件材料的热扩散率、润滑介质和材料表面层中的变形传播速率，而且还具有在磨合期间改变材料表面层的流变性能以及在磨合期间增加它们的功能。理论研究表明，三个参数对品质因数的影响最大：滑动速度、摩擦表面粗糙度和润滑介质。实验研究建立了摩擦系统稳态运行时品质因数、磨损率和摩擦系数之间的关系。结果表明，品质因数的增加使上述参数减小，而Qmax准则本身是摩擦系统适应工作条件的潜力的量度。
The definition of the quality factor of the tribosystem has been further developed, which, unlike the known one, takes into account not only the geometric dimensions of the tribosystem, thermal diffusivity of triboelement materials, lubricating medium and deformation propagation rate in the surface layers of the material, but also the function of changing the rheological properties of the surface layers of materials during running-in and their increase during running-in. Theoretical studies have established that three parameters have the maximum effect on the quality factor: sliding speed, roughness of friction surfaces and lubricating medium. Experimental studies have established the relationship between the value of the quality factor, wear rate and coefficient of friction during steady-state operation of tribosystems. It has been shown that an increase in the figure of quality factor reduces the above parameters, and the criterion itself Qmax is a measure of the potential of the tribosystem adapt to the operating conditions.
