Abstract:
     Method and arrangement for diagnostics of friction systems of motors. The object of the method consists in partial transfer of metallic microparticles dispersed in the lubricant into the solution to be analysed, then the sample is turned alkaline, after introduction of an electrode system the dependence of current on applied voltage in a given range of potentials is recorded, then a determined amount of triethanolamine is added to the analysed solution, the recording of current-voltage curve is repeated and from results of measurement the degree of wear and the technical state of the motor and the used lubricant is estimated. The detection electrode in electrolysis is a droplet of mercury of optimum radius between 0.05 and 0.4 mm, the renewed mercury meniscus electrode or the film mercury electrode. The arrangement and design of the whole tribodiagnostic system is described.
