Problems solved by technology

Among them, hot-dip galvanizing is one of the commonly used hot-dip galvanizing technologies at present, but molten zinc itself has a strong corrosive effect on hot-dip galvanizing equipment, which leads to problems such as increased cost, poor coating quality, low heating efficiency, and large energy consumption.

Abstract

The invention relates to the technical field of functional materials and discloses an anticorrosion treating method for an agricultural machinery metal part. The anticorrosion mechanism is researched,a rare earth metal compound is added into an anticorrosion coating, cleavage brittleness is prevented, and a coating material with the excellent corrosion resistance and friction resistance is obtained; a plasma spraying technology is selected to prepare the coating, the coating has the excellent anticorrosion property, and is resistant to thermal fatigue and thermal shock and more superior in mechanical property, the spraying efficiency is high, power consumption is small, and the coating quality is high; the prepared anticorrosion coating material enables the anticorrosion property of agricultural machinery to be excellent, corrosion resistance is improved, the application range is wider, the using function of the agricultural machinery metal part is improved greatly, and the life of the agricultural machinery metal part is prolonged greatly; and the specific working environment is met, the fault rate and the maintenance cost caused by corrosion friction and the like are lowered, the realistic significance in agricultural production efficiency improving can be achieved, and the anticorrosion treating method is extremely worthy of being used and popularized.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to an anti-corrosion treatment method for metal parts of agricultural machinery. Background technique [0002] Agricultural machinery refers to various machinery used in the production process of crop planting and animal husbandry, as well as in the initial processing and processing of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. Agricultural machinery in a broad sense also includes forestry machinery, fishing machinery, and rural sideline machinery such as sericulture, beekeeping, and edible fungus cu...
