Diffusion Coatings with the Participation of Titanium, Alumi¬nium and Silicon on Surface of the Steel 12X18H10T

Patterns of forming a multilayered diffusion coatings after complex saturation of titanium, aluminum and silicon to steel to improve heat resistance 12Cr18Ni10Ti were obtained and studied. The possibility of obtaining titanium-aluminum-silicon layers on steel 12Cr18Ni10Ti powder in containers with a gate in unpressurized conditions at temperature 1050 C and with duration 4 hours was studied. As initial components powders of titanium, aluminum, silicon, aluminum oxide, ammonium chloride were used.
