Changes of nickel micromechanical propertiesand tribological characteristics after electrolytic hydrogenation.
Abstract
Electrolytic hydrogenation influence on micromechanical properties and tibological behavior of nickel surface layers was studied. It was established that the treatment causes changes of nickel surface layers which are shown in increase of microhardness and decrease of ductility of the material. Nickel microhardness isincreased and its wear resistance de-creased with rising of hydrogenation current density. Surface destruction of the hydrogenated material takes place dueabrasion effect of hard and brittle wear products and cracks development.References
