Abstract
The invention discloses a novel rustless casting piece. The novel rustless casting piece comprises a casting piece body and an anti-rusting layer, wherein the casting piece body is packaged inside the anti-rusting treatment layer; the casting piece body is prepared from the following raw materials in parts by weight: 3-4.5 parts of carbon, 2-3 parts of silicon, 1-1.5 parts of manganese, 0.05-0.15 part of phosphor, 0.05-0.1 part of sulfur, 1.2-2.5 parts of copper, 1-1.8 parts of tin, 0.5-1.5 parts of chromium, 0.6-1.2 parts of zinc, 0.15-0.35 part of titanium, 0.5-1.5 parts of nickel, 1-2 parts of aluminum and the balance of iron, wherein the anti-rusting layer is a phosphatecoating. According to the novel rustless casting piece disclosed by the invention, composite elements are added into the material, so that each element inside the cast iron is unlikely to corrode and rust; meanwhile, the anti-rusting layer is combined to guarantee that the casting piece does not get rusty or has rusting amount lower than 1%, so that the problem that the casting piece is easy to rust is effectively solved, and therefore, the service life of the casting piece is prolonged.
Description
[0001] technical field [0002] The invention relates to the field of casting materials, in particular to a novel rust-free casting. Background technique [0003] With the rapid development of my country's machinery manufacturing and processing industry, China has become an important base for international mechanical processing. Therefore, higher requirements are put forward for the materials, functions, anti-corrosion and even decoration of various components that make up mechanical equipment. . [0004] Due to the particularity of the manufacturing process of castings, the surface of castings is prone to corrosion. If no corresponding measures are taken, the scope of use and service life of castings will be greatly reduced. Contents of the invention [0005] The technical problem mainly solved by the present invention is to provide a new type of non-rusting casting, adding compound elements to the material itself, so that the elements inside the cast iron are not easy to...
