METHOD FOR APPLICATION OF MULTILAYER WEAR-RESISTANT COATING TO ARTICLES FROM IRON AND TITANIUM ALLOYS Russian patent published in 1998 - IPC

FIELD: power and transport engineering for increasing the wear-resistance of turbine and pump blades, engine components and other equipment whose process of operation is characterized by concurrent effect of various types of wear. SUBSTANCE: method includes polishing of the surface to be coated to cleanness of R_a≤ 0,08 0.08 with subsequent cleaning with octadecylamine. Then a layer of transition metal of groups IV-VI of the Mendeleev Periodic Table is applied to the surface and a layer of oxide of the same metal and a layer of nitride or carbide of transition metal of groups IV-VI of the Mendeleev Periodic Table are applied. EFFECT: higher efficiency. 3 cl, 1 dwg
