氧化铁

In order to improve the reaction rate of pyrotechnical reagent, transition metal oxides, Fe2O3 and CuO, were added into potassium perchlorate and potassium nitrate respectively by mixing and crystallization methods. Accelerating rate calorimeter was used to study the catalytic behavior of TMO.

为了提高含高氯酸钾和硝酸钾烟火药剂的反应速率，应用混合法和结晶法将过渡金属氧化物氧化铁添加到含高氯酸钾的烟火药剂中，将氧化铜添加到含硝酸钾的烟火药剂中。

The maximal reaction rate of pyrotechnical reagent with potassium perchlorate added with Fe2O3 by crystallization method is 8.10 min-1, which is 4.09 times of that without catalyst. The time to maximal rate is 8.52 min, which is lower than that without catalyst by 92.8%. It was also found that CuO can catalyze pyrotechnical reagent with potassium nitrate, and the addition is better with mixing method.

结果表明，氧化铁对含高氯酸钾的烟火药剂具有催化作用，以结晶添加法催化效果最佳；此药剂的最大反应速率为8.10 min-1，是不含催化剂药剂的4.09倍；到达最大反应速率时间为8.52 min，比不含催化剂的药剂降低了92.8%。

The second step is that the needle-like β-FeOOH particles dissolve and recrystallize to form α-Fe2O3 particles.

第一步是氢氧化铁转化为针状的β-FeOOH粒子；第二步是针状的β-FeOOH粒子溶解再结晶形成α-Fe2O3微粒。

Result shows that the oxidation resistance can only be improved a little by this modification, and some copper was oxidized into cuprous oxide At last, fine copper powder was treated by potassium rhodanate solution andβ-CuSCN coating layer was produced.

实验尝试了用氧化铁包覆铜粉以对其改性的方法，结果表明改性后铜粉的抗氧化性能有一定的提高，但在处理过程中部分铜粉被氧化生成了氧化亚铜。

Selecting water-borne styrene/acrylic anti-rust latex of soapless polymerization technology as binder,iron oxide red and aluminum triphosphate as anti-rust system and nano SiO_2 paste,we prepared water-borne nano-modified styrene/acrylic anti-rust primer,properties of which reached the level of solvent-borne alkyd antirust coatings.

本试验选用无皂聚合工艺制备的水性苯丙防锈乳液为基料，氧化铁红与三聚磷酸铝组成防锈体系，添加纳米SiO_2浆料，制备的水性纳米改性苯丙防锈底漆性能达到溶剂型醇酸防锈涂料的水平，并分析了乳液、防锈颜料、纳米SiO_2对水性苯丙防锈底漆性能的影响。

The squamaceous ferric oxide has been homo-dispersed in the film, to form the good shielding interface, and reducing permeability of water and the breathing property of the film.

鳞片状的云母氧化铁均匀分散在涂层中，形成良好的屏蔽介面，降低了涂层的透水性、透气性，具有优异的防腐蚀能力。

The inhibition mechanism of MoO42- was that MoO42- transformed the hydrate ferrous oxide deposition film from anions selective to cations selective,and the cathodic process of underscale local corrosion was suppressed when it migrated into OCC.Meanwhile, the migrated MoO42- resulted in increasing the impedance of the film on the substrate metal and so inhibited the anodic process of the corrosion reaction inside the OCC.

MoO42-的作用机制在于使水合氧化铁腐蚀膜由阴离子选择性变为阳离子选择性，H+可以从膜下扩散出去，而Cl-难以扩散到膜下富集，抑制了腐蚀反应的阴极过程；同时MoO42-迁入闭塞区后增大了电极表面膜层阻抗，抑制了腐蚀反应的阳极过程。

Wear experimental results showed that the wear rate of Ta+C-implanted steelwas increased and the friction coefficient dropped significantly compared with that of unimplanted H13 steel.

但当模具温度超过400 ℃时，工件铝材表面就会形成坚硬的Al2O3，而模具氮化表面将形成疏松而容易发生点腐蚀的氧化铁，从而导致模具在预热阶段就开始腐蚀，加上Al2O3引起的严重磨损，模具承载表面会过早和突然破损。
