Graphene was first obtained at the beginning of the 21st century, and since then various methods have been developed for its synthesis. This variety is explained by the natural layered structure of graphite. A large number of methods is based on the idea of separating graphite layers. They are considered relatively cheap, productive and available in almost all laboratories.
The influence of the profile, surfacing on the formation of the weld by automatic submerged arc wire with powder brand CW80Cr20B3Ti. As a result, design of experiments established the relationship between the geometric dimensions of the seam and the depth of penetration of current value and welding speed. The resulting optimal mode of deposition used in forming the roller for extra vibration substrate.
The possibility of electrophoretic deposition of colloid solution based on liquid glass have been studied. Parameters of Na2O-TiO2-SiO2 coating applied over nickel surface have been established.
