Šta su legure na bazi galijuma

Legure na bazi galijuma su zasnovane na galijumu, uz dodavanje drugih metala, kao što su volfram, kobalt, titan, gvožđe i drugi metali, da bi se dobile legure na bazi galija.

Ni65WC je legura na bazi nikla, a postoji i nerđajući čelik na bazi nikla, kao što su 304, 316 i drugi nerđajući čelici. Legure na bazi nikla sa dodanim volframom, molibdenom, kobaltom, titanijumom itd. obično imaju visoku tvrdoću, dobru otpornost na habanje i dobru otpornost na visoke temperature. Obično se koriste u posebne svrhe, kao što su legure za rudarstvo, legure otporne na habanje, premazi, legure alata i jak magnetizam.

In addition to bearing abrasive wear, adhesive wear and other types of wear, a class of nickel alloys that also withstand medium corrosion and high temperature oxidation. Therefore, the working conditions of nickel-based are much more complicated than those of general wear-resistant steel and wear-resistant cast iron. The chemical composition of wear-resistant gallium-based alloy is (%): C 0.10～0.20, Mn 0.25, Si 0.60, Cr 14.00～17.00, Mo 4.50～6.00, Al 2.5～3.50, Fe 8.00～12.00, Ti 1.50～2.50, Ni margin. The tensile strength at 820°C was 520 MPa and the elongation was 3%. This material is generally used as wear-resistant parts that work in air or low-lubricating liquids, such as valves, pump parts, pistons, piston rings, seals, brakes, thrusters in petrochemical equipment, atomic energy equipment, and jet aircraft and internal combustion engines. Rods, vanes and blades, etc.
