Soluble Biodegradable Magnesium Alloys In Oil Extraction And Sewage Treatment Plugging Mouth Processing

A degradable magnesium alloy material, widely used in the field of oil extraction and sewage treatment plugging mouth processing, processing performance can be relatively high parts. Material can be completely degraded, there is no easy card astringent, blocking the channel problem.

Taking advantage of the excellent castability of magnesium alloys, magnesium alloys can be used to manufacture some structural parts in aircraft engines with complex shapes and small bearing forces, such as engine accessory casings, helicopter gearboxes, and the casing of the drive transmission system. ZE41 magnesium alloy castings are used in the manufacture of the AE-3007 engine intermediate casing for the "Global Hawk" UAV, and WE43 magnesium alloy castings are used in the manufacture of the F-110 engine accessory casings for F-16 and F-18 aircraft. The F-119 engine gearbox housing for the F-22 aircraft.

Magnesium alloy has good damping effect, and its vibration reduction effect is better than that of aluminum alloy [6]. In December 2014, my country's first set of civil aviation magnesium alloy seats was successfully trial-manufactured. As the first set of civil aviation magnesium alloy seats independently developed, designed, manufactured and assembled in China, the final assembly work was completed in AVIC Hubei Hangyu Jiatai Aircraft Equipment Co., Ltd., marking the first set of magnesium alloy for civil aircraft in my country The trial production of the seat was successful. The main structure of the same aluminum alloy seat weighs 9.3kg, while the seat set is reduced to 7.18kg, a reduction of 22.8%. In February 2015, a German seat manufacturer also successfully produced a magnesium alloy aviation seat, which maintains the same strength and toughness as the aluminum alloy seat while reducing the weight by 25%, which marks the application of magnesium alloy in the aviation field. new level. It can be predicted that magnesium alloys will become an important measure for the lightweight of aircraft in the near future, and will make a huge contribution to the weight reduction of aerospace materials in the future.

Although the density of magnesium alloy is low, its specific strength and specific stiffness are similar to those of aluminum alloy and steel. It is a lightweight and high-strength material, so it can be used in the manufacture of parts that bear various loads such as impact load, alternating load, vibration load, etc. Such as aircraft skins and cabins, wall panels, engine components, auxiliary power units, helicopter gearboxes and transmission boxes, etc.
Research results show that rare-earth high-strength magnesium alloys can replace some medium-strength aluminum alloys, and some of them have properties that can reach or even exceed high-strength 2XXX series aluminum alloys, and are used in fighter aircraft [5]. With the development of magnesium alloy preparation technology, the specific stiffness, heat resistance and corrosion resistance are further improved, and the application scope is further expanded. missiles and satellites.
