The making technology comprises 1, heating a high-carbon steel plate to a temperature of 100-200 DEG C, immersing the high-carbon steel plate in a cold hydrochloric acid solution in vacuum for cooling and then cleaning the high-carbon steel plate through deionized water, 2, carrying out shot blasting on the high-carbon steel plate obtained by the step 1, removing ash on the high-carbon steel plate subjected to shot blasting, smearing the high-carbon steel plate with a rosin liquid, putting the high-carbon steel plate with the rosin liquid into a muffle furnace and heating the high-carbon steel plate to a temperature of 200-400 DEG C, 3, putting the high-carbon steel plate obtained by the step 2 into nitrogen at a temperature of 5 to -2 DEG C and carrying out cooling, and 4, carrying out zinc impregnation treatment on the high-carbon steel plate at a temperature of 100-150 DEG C and then cooling the high-carbon steel plate to the room temperature through nitrogen.

Description

technical field [0001] The invention belongs to the field of surface treatment and preparation of alloy materials, in particular to a manufacturing process of antirust backing plates for marine pipeline components. Background technique [0002] In addition to having lighter weight characteristics, marine alloy materials must also meet the working requirements in the marine environment, that is, they should have good acid and salt corrosion resistance, which is the basic feature that distinguishes marine materials from other materials. However, ordinary alloys will corrode under the action of some high temperature and high pressure, which will affect the structural strength. If the existing marine component materials are all made of stainless steel and other materials, not only the cost is high, but also the processing is more difficult than ordinary materials. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome th...
