  • Theoretical justification of increase of productivity of galvanic sedimentation of coverings on the restored surfaces of details of cars

    Increase of productivity of processes of sedimentation of coverings on the restored surfaces of details of cars without decline in quality of the received deposit is a main objective on the way of improvement of galvanic processes. Productivity of galvanic sedimentation depends on the size of potential of the cathode and the anode; from concentration of components of electrolyte about a surface of sedimentation (cathode); from uniformity of delivery and dispersal of ions of metal on a sedimentation surface; from quantity of active sites of the cathode; from nature of passivation of the cathode; from temperature of electrolyte and from the speed of the movement of electrolyte in prikatodny space. Very strongly passivating of a cathodic surface limits the possible growth of productivity of galvanic sedimentation. Passivating consists in education on a surface of the cathode of the continuous passive film consisting of hydrogen, products of reaction of metal with electrolyte components, oxygen of air and foreign inclusions. The passive film is almost insoluble and disturbs electrocrystallization process, shielding a cathodic surface. And cathode covering speed a passive film directly depends on density of cathodic current. It is possible to assume that at achievement of some value of density of cathodic current the speed of formation of a passive film will exceed, the speed of delivery of ions of metal to a cathodic surface and origin of crystals of the besieged metal will become impossible. And on the remained active sites of the cathode where the passive film is absent or has the smallest thickness and growth rate, there will be centers of growth of crystals of metal (dendrites) on which there will be a concentration of the main processes of electrocrystallization. That is the cathodic surface of the restored detail will become covered by the local centers of sedimentation of metal – dendrites. The passive film interferes with growth of limit density of cathodic current at which receiving qualitative electroplated coating is possible. Mechanical elimination of a passive film during sedimentation of a covering considerably facilitates process of electrocrystallization and formation of a layer of metal on the processed detail surface, provides increase of uniformity of the received layer of metal and its microhardness, and also will prevent active formation of local sites of growth of dendrites at the high density of current.

  • The device for restoration of internal cylindrical surfaces of details of mobile equipment galvanomekhanichesky sedimentation of coverings

    Carry to the main advantages of galvanic ways of restoration: possibility of formation of a layer from several micrometers thick to 1-2 mm. metal or a combination of metals with the set properties, restoration "in the size", that is without the subsequent machining, simultaneous restoration of several surfaces and use of a small amount of electrolyte. A number of the devices allowing to provide the demanded conditions is developed for implementation of galvanomekhanichesky sedimentation of coverings. As the activating elements in these devices generally apply abrasive materials which working surface, in the course of work, "is salted", that is it is hammered with cutting products. It considerably reduces efficiency of activation of the cathode and uniformity of the received deposit in view of introduction in the formed layer the activating elements of products of activation. The offered device developed by Zakharov Yu.A. and Spitsyn I.A. it is deprived of such shortcoming in view of application of the activating elements in the form of leaders and the conducted abrasive rollers connected by a belt drive. For elimination of this lack of the existing devices by Zakharov Yu.A. and Spitsyn I.A. (patent No. 2503753) the device was developed for galvanomekhanichesky sedimentation of coverings on internal cylindrical surfaces of details. Difference of the offered device is that at sedimentation of an electrodeposit, the conducting and conducted rollers, being rolled on the activated cathode surface, rotate with various district speed because of their various diameter. As pulleys of leaders and the conducted rollers are connected by a belt drive, to the transfer relation no more than 0,8-0,9, on shaft of rollers there is various district force forcing the conducted rollers to slip rather cathodic surface. It provides better removal of the passivating film and continuous change of the surface of the activating roller contacting to the activated cathodic surface. Thus, the free surface of the activating roller is washed by a channel of electrolyte, being cleared of activation products that interferes with formation of so-called "zasalivaniye" of a wor1king surface of the activating elements (rollers).

  • Experimental installation for laboratory researches of galvanomekhanichesky sedimentation of zinc from flowing electrolyte on the restored surfaces of details of mobile equipment

    Improvement of technological process of galvanizing in flowing electrolyte without decrease in its reliability and quality of the received deposit can be carried out by carrying out anode etching of the processed surface directly in the main electrolyte of sedimentation. And, providing such conditions of anode etching at which, the details which are formed on a surface products of reactions easily are removed a channel of electrolyte is possible. For the purpose of identification of extent of influence of technology factors on anode dissolution of the processed surface it is necessary to conduct elektrokhikmichesky researches. The installation including electric was for this purpose developed and made and gidravklichesky speak rapidly. The Elektkrichesky part contains power-supply circuits of an electrolytic cell to the asymmetric variables odnopoluperiodno straightened, dvukhkpoluperiodno straightened by current and straightened by current with the lowered pulsation, and also a chain of heating of working electrolyte. The hydraulic scheme of experimental installation includes: the kisloktostoyky electric pump, pipelines, filters, the device for an electrolytic precipitation of coverings and a bathtub with electrolyte. Electrolyte in a cell moved by means of the electric pump. Giving changed in steps, due to change of diameter of the section through passage of the giving pipeline by means of replaceable inserts. Authors of the device for electrolytic drawing coverings are Zakharov Yu.A. and Spitsyn I.A. (patent No. 2155827). The design allows: to increase the speed of a channel of electrolyte; to carry out activation of the cathode, using energy of a channel of electrolyte; to increase the accuracy of copying of the cathode the activating elements; to use higher density of current and to reduce power consumption of the device. Electrolyte, in the course of sedimentation, was constantly filtered. As filtering material used fiber glass. The filter if necessary it is possible to dismantle and wash out quickly. Such filtering element slightly interferes with a channel of electrolyte, is simple in service, is cheap and quite sufficient. Thus, the offered design of experimental installation allows to conduct necessary researches of process of sedimentation of a zinc electrodeposit for its improvement.
