与chromium相关的网络例句 [注：此内容来源于网络，仅供参考]

To restore the ability of chromium can be dissolved in sulfuric acid, hydrochloric acid and High-FE acid and release hydrogen, but also of pure chromium with aqua regia does not work, when there is the presence of halogen ions in the acid can not be long-term stability, high temperature with alkali, hydrogen sulfide, sulfur steam, phosphorus, ammonia, such as carbon monoxide and water vapor reaction of the corresponding compounds, in the high temperature reaction of silicon into the silicide also chromium, chromium alloys with many metals generate a wide range of industrial applications, such as chromium-manganese stainless steel is used extensively for chemical plants.

铬的还原能力强，能溶于硫酸、盐酸和高FE氯酸而放出氢气，但纯铬连王水也不起作用，当有卤素离子存在时，在酸中不能长期稳定，高温时能与强碱、硫化氢、硫蒸汽、磷、氨、一氧化碳和水蒸汽等反应生成对应的化合物，在高温下还能与硅反应成硅化铬，铬能与许多金属生成合金广泛在工业上应用，如铬锰不锈钢大量用于化工设备。

The results show that the addition of certain manganese in high chromium cast iron leads to a re-partitioning of alloy elements between austenite and carbide and a dropping in equilibrium phase transformation temperature although it's inappreciable for the influence of manganese on mass fractions of every phase in this cast iron. There is about 87 percent ledeburite under thermodynamic equilibrium condition and 23 to 32 percent M7C3 type carbide under thermodynamic non-equilibrium condition in the microstructure of 3C-l5Cr-4Mn-0.75Si system high chromium cast iron. Furthermore, the improvement of austenite stability and hardenability of manganese alloyed high chromium cast iron may been expected because there is a substitution between manganese and chromium that has been suggested by thermodynamic calculations.

结果表明，锰虽然对高铬铸铁中的各相数量影响不大，但一定数量的锰存在促使合金元素在奥氏体和碳化物两相中的重新分配，并降低平衡相的转变温度；在平衡条件下3C-15Cr-4Mn-0.75Si系高铬铸铁中菜氏体数量约占87%，而非平衡条件下M7C3型碳化物数量在23%-32%之间，且奥氏体中锰铬互替现象保证了奥氏体的稳定性和加锰高铬铸铁的淬透性。
