Abstract:
The high efficiency of the polymer coating is achieved only by the proper choice of thermal and other conditions during the formation of its structure. The aim the work is to study only the initial stage of physical and chemical processes by the formation of the structure of polymer coating, namely, the creation of a primer adhesive layer after the application of monomer paint solution on the steel sheet before to the polymerization.

Abstract:
Cathodic protection is applied especially to protection of coating fault on a buried pipe line in a soil. According to some authors, the mechanism of cathodic protection of carbon steel is a shift of open circuit potential into the immunity region or reducing of anodic reaction rate in the active state.

Abstract:
CoNiCrAlY bond coats manufactured by the high-velocity oxygen-fuel spraying (HVOF) and cold gas dynamic spraying (CGDS) deposition technique have been investigated and comparison of phase modification is presented in the paper. Even though both techniques accelerate powder particles with high kinetic energy, the resulting coatings differ considerably in their microstructures. [..]

Abstract:
Laser technologies are among the unconventional methods of heat treatment and machining. Among the biggest advantages of laser quenching (hardening), it can be included high speed and process efficiency, a narrow thermally affected area and the possibility of processing complicated parts in shape that could not be workable with common conventional methods.
