High temperature steam oxidation test of metal materials

High-temperature steam oxidation test of metal materials Oxidation test of metal materials under high-temperature steam conditions. Zhongke Testing Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various metal materials, and provides professional high-temperature steam oxidation testing services for metal materials.

Metal materials are usually divided into ferrous metals, non-ferrous metals and special metal materials.
1. Ferrous metals include chromium, manganese and their alloys.
2. Non-ferrous metals refer to all metals and their alloys except iron, chromium and manganese, which are usually divided into light metals, heavy metals, precious metals, semi-metals, rare metals and rare earth metals.
3. Special metal materials include structural metal materials and functional metal materials for different purposes. Among them are amorphous metal materials obtained through rapid condensation processes, as well as quasicrystalline, microcrystalline, and nanocrystalline metal materials; there are also special functional alloys such as stealth, hydrogen resistance, superconductivity, shape memory, wear resistance, vibration reduction and damping, and metal matrix composite materials.

1. The metal material sample undergoes an oxidation reaction in high-temperature steam, and part of the metal is converted into oxides, resulting in metal loss. The resistance to high-temperature steam oxidation of metal materials is evaluated through changes in sample mass or oxide film thickness.
2. The test results should record the changes in mass of the sample and changes in oxide film thickness. The thickness measurement accuracy is not less than 1 μm. When the oxide film peels off on the sample, it should be noted in the report.
3. When collecting weight gain data, the number of samples at each test point should be no less than 3; when measuring the stability of antioxidant rate, the number of test points should be no less than 5.
4. When analyzing the steam oxidation resistance of the sample, a comprehensive analysis can be made from the aspects of oxidation weight gain, oxide film thickening, oxide film morphology and peeling.
