Abstract

The invention discloses a production process for antirust coating of metal daily necessity. The production process specifically comprises the following steps: step 1, transferring the metal daily necessity to a workbench, and grinding the surface of the metal daily necessity by using abrasive paper; step 2, putting the metal daily necessity ground in the step 1 into an ultrasonic cleaning machine, adding clear water and a sodium hydroxide solution, and quickly cleaning by utilizing ultrasonic waves; step 3, adding the metal daily necessity cleaned in the step 2 into a drying box for drying treatment, quickly blowing-drying in warm air, removing dirt and rust spots on the surface of a base body, and carrying out pretreatment operation; and step 4, spraying Cr and Mo powder to the surface layer of the pretreated metal daily necessity. According to the invention, a CrMo base layer is prepared through heating and curing, the adhesiveness of outer layer nitriding treatment is improved, a layer of nitride is formed on the surface of the nitrided metal daily necessity, high antirust and anticorrosion capacity and high strength are achieved, oxidation and stripping are not likely to happen, durability is achieved, and therefore the service life of the metal daily necessity is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of coating production, and in particular relates to a production process of an antirust coating for metal daily necessities. Background technique [0002] Combined with the development needs of today's global circular economy and low-carbon economy, people's demand for materials tends to be practical, beautiful, economical, and durable. Surface engineering technology stands out from various technologies and has received great attention. The surface of metal daily necessities is easy to stick to oil and rust, and most of them occur in the process of mechanical processing and storage in the factory. Therefore, the use of surface treatment technology to improve the anti-rust performance of the surface of the material will improve the safety and reliability of its use, facilitate cleaning and extend the life of the product. The service life has very important significance and development prospects. The existing ...
