ABSTRACT:
A method for diagnosing friction systems involves the partial transfer of metallic microparticles dispersed in lubricant into a solution to be analyzed. The sample is turned alkaline, and after introduction of an electrode system, the dependence of current on an applied voltage in a given range of potentials is recorded. A determined amount of triethanolamine is added to the analyzed 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 of the used lubricant is estimated. The detection electrode in electrolysis is a droplet of mercury having an optimum radius between 0.05 and 0.4 mm, a renewed mercury meniscus electrode or a film mercury electrode. An exemplary apparatus for performing the method is disclosed.
