Zhonghuan Electric Furnace Proudly Launches the High-Temperature, High-Speed Water-Oxygen Environment Corrosion Tester
2025-03-10
Tianjin Zhonghuan has launched a new product: a high-temperature water–oxygen environment corrosion tester (static type) with a high degree of integration, capable of operating at temperatures up to 1600°C. The flow rates of both gas and water vapor are stable and precisely controllable, with current options ranging from 30–300 mL/min to 100–1000 mL/min. By employing experimental testing methods, this instrument accurately simulates the extreme service environments experienced by alloys and coatings in turbine engines and gas turbines, conducting cyclic tests for thermal corrosion and steam oxidation to reliably evaluate the thermochemical stability of materials.
The high-temperature water–oxygen corrosion testing system employs laboratory-based test methods to accurately simulate the high-temperature, high water-vapor partial-pressure, and high water-vapor velocity conditions found in turbine-engine operating environments. It conducts cyclic tests on materials to evaluate their thermal corrosion and steam oxidation corrosion, thereby providing a reliable assessment of their thermochemical stability. The system is capable of independently controlling steam flow rate, vaporization temperature, and gas preheating and mixing, enabling the generation of gases with constant humidity and integration with high-temperature thermal reactors. The equipment comprises an air-inlet control unit, a liquid-delivery unit for precise control of liquid feed rate, a heated evaporator for uniform water vaporization and gas mixing, heat-traced piping, and a heated reactor, among other components. It is primarily used in the evaluation of various functional ceramics, structural ceramics and ceramic-matrix composites, ultra-high-temperature alloy materials, and high-temperature thermal-barrier coatings.
