Abstract

The invention relates to a preparing process of a nanometer complex alloy co-permeation anticorrosion coating layer, which belongs to the technical field of the metal surface modified or alloying treatment. The preparing process comprises computer analog computation, preliminary treatment of steel members, complex configuration of co-permeation agent, energizing agent, active agent and filling agent, co-permeation processing of steel members and after-treatment of steel members. The preparing process has the advantages that firstly, the computer simulation is adopted to calculate optimal machining conditions, and to reduce the various consumption under the conditions; secondly, partial zinc powder is replaced by aluminum powder as the co-permeation agent, the hardness and the wear resistant property of a co-permeation layer are improved, and the co-permeation cost is reduced; thirdly, nanometer mixed rare earth oxide with low price and good effect is adopted as the energizing agent; fourthly, the co-permeation layer contains no heavy metal cadmium, is environmentally protective and is free from pollution; fifthly, the preparing process has no hydrogen embitterment damage, the processing temperature is low, the time is short, the hydrogen embitterment damage occurring on the co-permeation layer is avoided, and the energy consumption is reduced simultaneously.

Description

technical field [0001] The invention belongs to the technical field of metal surface modification or alloying treatment, and in particular relates to a preparation process of a nano-multiple alloy co-infiltration anti-corrosion coating. Background technique [0002] At present, there are many surface anti-corrosion treatment processes for the existing main metal coatings, such as electro-galvanizing (electroplating, ion plating or ion implantation, etc.), cold galvanizing (mechanical plating, brushing plating, etc.), hot-dip galvanizing (including Hot dip coating, thermal spray coating) and powder zinc coating, etc. [0003] Electrogalvanizing, cold galvanizing and hot-dip galvanizing processes have been gradually eliminated due to the disadvantages of large pollution, high energy consumption and poor performance. The processing temperature of powder galvanizing is high, generally reaching 350-420 ℃, the heating and holding time is long, and the energy consumption is large;...
