摘要: The invention relates to a method for measuring the interfacial shear strength under fully plastic contact between flat plates, which is characterized in that two plates are contacted with each other sliding manner measure strength, surface of one plate coarse and smooth. comprises following steps: A. still smooth slides relative at speed u; B. lubricant be tested supplied zone form fluid hydrodynamic lubrication load applied plates; C. different hardness needed completing one-time measuring, loading carried out on respectively, values coefficient friction respectively measured solved obtain taus0 alphas. device obvious technical effects have advantages large pressure range tested, simple compact structure, easy implementation, low manufacturing cost use cost, measurement higher precision, etc.
