구형 금속 분말 GH5188 코발트 기반 고온 합금 분말

제품 캐릭터 GH5188 is a solid solution strengthened cobalt based high-temperature alloy, which is strengthened by adding 14% tungsten to give the alloy excellent high-temperature thermal strength. At the same time, adding a high content of chromium and trace amounts of La gives the alloy good high-temperature oxidation resistance. Compared to nickel based high-temperature alloys, GH5188 has more good creep resistance, thermal corrosion resistance, fatigue resistance, and high temperature strength. GH5188 has excellent formability, welding and other process properties, making it suitable for manufacturing parts for aircraft engines that require high strength below 980 ℃ and anti-oxidation below 1000 ℃. In the 1980s, GH5188 alloy was applied to components such as vortex plates and flame deflectors in turboshaft eight aircraft engines. Currently, some aircraft engines use GH5188 alloy sheets to prepare high-temperature components such as combustion chamber walls, outer walls, and sealing plates.   2.사양 GH5188 powder
