Mechanical Characteristics of Steels with a Gas-Phase Nickel Coating

  • 2 Accesses


A promising method of corrosion protection of steel parts in chemical engineering is a gas-phase coating, which has a high density and chemical stability to the influence of fluorine and good adhesion to substrate over entire coating area even for parts of complex shapes. The characteristics of the static and fatigue fracture of BSt.3sp, 40, and E10 steels are considered after coating with gas-phase nickel of different thicknesses (5, 10, 20, 50, and 100 μm) at various substrate temperatures (130, 160, 180, and 200°C). The gas-phase nickel coating 30 μm thick of steel parts can be considered useful due to its high chemical stability and the simplicity of the technological process in spite of some decrease in the mechanical characteristics.
