Corrosion is a destructive phenomenon that all materials in nature have to face.It will not only cause huge losses and resource consumption,but also endanger human health and safety.The effective anti-corrosion can not only beautify the appearance of the product,but also prolong the service life of the equipment.For enterprises,reducing process costs means creating economic benefits.On the premise of ensuring the anti-corrosion quality of products,this paper effectively reduces the corrosion protection cost of steel structural parts by controlling surface roughness,coating matching,spraying equipment,film thickness,repair rate and packaging protection.
