Title: Method for electrochemical regeneration of surfaces of mechanisms friction couples
Inventor: TURCHYNSKYI PAVLO YEVHENOVYCH
Filed: 2001-02-16
Abstract: A method for electrochemical regeneration of the surfaces of mechanisms friction couples comprises filling the areas of the friction couple – the cathode and electrically insulated anode-insertion – with conductive fluid, with application of electric current to the cathode and the anode-insertion. At that the anode-insertion is made of metal, and installed outside the friction couple; and the process of regeneration is implemented at minimal rate or rotation of the mechanism. Conductive fluid is used, this is made on water base, with following composition mass %: polyethylene-glycol 1.0 – 6.0, metal salt 0.1 – 0.3, sulphuric acid 0.01 – 0.1, water – the rest. This method makes it possible to carry out regeneration of the worn surface of the mechanism, for instance a combustion engine, without dismounting it.
