Multifunctional cluster system for reactive ionized plasma synthesis of compositional compounds PP137
Purpose and areas of usage
The technology for drawing antifriction coatings on lead - based alloys - lead - tin - copper and lead - tin, used in nodes of friction of parts and mechanisms, was developed.
Gist of development
The proposed electrolytes for electrodeposition of alloys consist of mesylate (methanesulfonate) of metals and composition of organic additives of MSA. It includes antioxidants and surfactants, which provide a stable operation of the electrolyte. The fine - crystalline light - gray matte coatings with lead - tin - copper alloy (90/8/2% ) and lead - tin (88/12% ) with a stable composition in a wide range of current densities (1 - 5 A / dm²) were obtained at a temperature of 18 - 25 ° C.
Main advantages of development
The proposed development is more environmentally safe than conventional boron fluoride technologies. Using electrolytes based on methanesulfonate acid instead of boron fluoride solutions can significantly reduce waste disposal costs in galvanic production. The proposed composition of MSA inhibits the oxidation of Sn (II) ions, preventing the loss of an expensive component of the electrolyte, which also increases the economic competitiveness of the proposed technology.
The results of the development can be used at the enterprises of mechanical engineering, ferrous metallurgy, automobile and shipbuilding.
