Embodiment
[0044] In this embodiment, the first Ni-CeO on the low carbon steel 2 and Ni-Y 2 o 3 Preparation of CeO by Composite Electroplating and Diffusion Chromizing 2 and Y 2 o 3 Modified chromized coating as an example:
[0045] The composition of the chromized coating modified by rare earth oxides: the chromium content of the surface layer is 35-55 parts, and its composition is in a gradually decreasing distribution state from the surface to the inside. Oxide CeO 2 or Y 2 o 3 It is 1-4 parts, and the balance is M (Ni in Ni, Fe or Co), which comes from the composite coating;
[0046] The preparation method is as follows: the M-rare earth oxide composite coating is prepared by conventional composite electroplating technology. M is Ni, Fe or Co, and generally selects the same element as the main component of the matrix material. The matrix material is Fe, Ni, Co, carbon steel, alloy steel with poor oxidation resistance, commonly used sulfate system (MSO 4 ) plating solution....
