ELECTRODEPOSITION OF COPPER-TIN ALLOY USING VIBRATION AND A MAGNETIC FIELD
Background. The object of research is an electrolyte for deposition of coatings with a copper-tin alloy; the subject of research is the processes of electrodeposition of coatings with a copper-tin alloy at stationary and non-stationary modes of electrodeposition, such as cathode vibration and electrolyte conversion to a magnet. The research is aimed at discovering technological and kinetic regularities of copper-tin alloy electrodeposition in conditions of cathode vibration and a magnetic field. Materials and methods. In the course of experiments the authors used the following methods: classification, analogues for application of adjacent fields of science and technology; technologies of galvanic coating with alloys; standard methods of determination of the composition of the obtained coatings. Results. The authors revealed technological and kinetic regularities of electrodeposition of coatings made of a copper-tin alloy allowing to choose preferable modes of electrolysis in conditions of cathode vibration and in a magnetic field. In order to obtain an alloy of a certain composition the authors developed a multifunctional regression equation that shows the correlation of the content of tin in the alloy and the input parameters influencing the process. Conclusions. The authors discovered that the cathode vibration and magnetic field superimposition on the electrolyte increase current output, operating current density 4 times and 1, 5 times respectively and improve the outlook of coatings with a copper-tin alloy.
