Ce Alloy | New aluminum alloy is more heat-resistant

The castability of ce alloy is comparable to that of aluminum-silicon alloys, which is very easy to process, and the stability of intermetallic compounds eliminates many heat treatment links. The heat resistance of aluminum-cerium alloys is more suitable for internal combustion engines. Measurements show that the new alloys remain stable at 300°C (572°F), the temperature at which traditional alloys have begun to melt. Additionally, the stability of the new alloy reduces the need for heat treatment. Aluminum-cerium alloys can not only directly improve the fuel efficiency of the engine through operating temperature, but also through the use of small aluminum base components or the use of aluminum alloys instead of cast iron in light engines such as cylinder blocks, transmissions and cylinder heads.

Cerium aluminum

It mainly includes cerium-based pure aluminum coating and epoxy vinyl ester paint coating. The cerium-based pure aluminum coating is a thermal spray coating with aluminum as raw material and cerium element added. The epoxy vinyl ester paint coating is cerium Sealing layer and functional coating of Ce aluminum thermal spray coating. The weight percentage of cerium-based pure aluminum coating is 0.05-0.50%, other impurities iron + copper + silicon ≤ 0.30%, the balance is aluminum, and magnesium can also be added as an auxiliary. The production method of pure aluminum coating is as follows: It is processed into wire or powder to make a Ce aluminum spray coating on the steel surface by thermal spraying technology. The epoxy vinyl ester paint coating is made of epoxy vinyl ester resin as raw material, and carbonized silicon and aluminum powder or aluminum powder slurry are added. Epoxy vinyl ester paint is used as the sealing layer, intermediate layer and surface layer of Ce series aluminum coating, and other paints can also replace one or all of them.

ce alloy | fusion method

Aluminum rare earth alloy has excellent properties such as small specific gravity, high strength, high temperature resistance, corrosion resistance, etc. It has wide application prospects and great development breadth and depth. Cerium has always been a "bad" by-product in rare earth mining, with a relatively high added value However, the development and application of aluminum-cerium alloys in the fields of aero-engines and vehicle internal combustion engines has made the demand for cerium and aluminum-cerium alloys increasingly strong. Therefore, the research on the preparation process and properties of aluminum-cerium alloys is important for It is of great significance to improve the value of cerium products and promote the balanced and healthy development of the rare earth industry. At present, the main production method of aluminum alloys is fusion method.

Cerium metal

Cerium is also used as an excellent environmental protection material, and the most representative application at present is the catalyst for automobile exhaust purification. Adding cerium to the commonly used three-way catalysts of precious metals (platinum, rhodium, palladium, etc.) can improve catalyst performance and reduce the amount of precious metals. The main pollutants in automobile exhaust are carbon monoxide, hydrocarbons and nitrogen oxides, which will affect human hematopoiesis. function, form photochemical toxic fumes and produce carcinogens, causing damage to humans, animals and plants. The three-way purification catalytic technology can fully oxidize hydrocarbons and carbon monoxide to generate carbon dioxide and water, and decompose nitrogen oxides into nitrogen and oxygen (hence the name three-way catalysis). Precious metals such as platinum, rhodium and palladium are excellent catalytic materials for exhaust gas purification. However, they are expensive and have high requirements on engines and gasoline, which limit their wide application. Adding cerium to the catalyst can significantly reduce the amount of precious metals and improve the catalytic performance, which greatly reduces the price of the catalyst. In the United States, automobile exhaust purification catalysts have become the largest user of rare earth consumption. Cerium oxide can also be used as a photocatalyst with nano-titanium oxide, which is used in antibacterial ceramics and oxygen-rich ion environmental protection coatings.
