查询词典 against corrosion

Nano titanium dioxide is of favorable biological and chemical inertness, strong oxidizability, low cost and long-term stability against photocorrosion and chemical corrosion. Nano TiO_2 and TiO_2/SiO_2 thin films are used photocatalysis degradation materials and self-cleaing materials, and can kill bacteria and virus.At present it is the hot spot in the research of photocatalysis, and it is of great value in the practical applications.

由于纳米TiO_2具有良好的生物和化学惰性、较强的氧化性能、低成本、以及对光腐蚀和化学腐蚀的稳定性等，故其薄膜不仅能用作光催化降解和自洁净材料，还能杀死细菌及病毒，是目前光催化材料的研究重点，具有广阔的应用前景。

Using modified conventional powder metallurgy process for sintered Nd-Fe-B magnets , including annealing of ingot alloy, hydrogen decrepitating, modified jet mill and adding additive during jet milling, we have mass-produced high performance and high corrosion resistance sintered Nd-Fe-B magnets from a conventional ingot alloy without strict protections against oxidation.

利用改进的传统粉末冶金工艺(铸锭热处理、氢爆、改进型气流磨设备以及在气流磨中掺入添加剂等)，在无严格的防氧保护情况下，从传统合金铸锭出发，工业化生产出具有高耐蚀性的N48～50档烧结Nd-Fe-B 磁体。

The results show that the addition of accelerators to the treating bath will accelerate the coating formation, and the added ammonium salt and chloride will change the Ce content in the coating from 5.93% to 4.15% and 9.27%, respectively. The added accelerators of ammonium salt and chloride could also increase the coating anti-corrosion performance to 2.6 times and 6.6 times against that treated without accelerator, respectively, and increases the micro-hardness of the Al surface from HV68.8 to HV389 and HV450, respectively.

结果表明：处理液中添加成膜促进剂可提高转化膜的生长速度，并且添加铵盐、氯化物后转化膜的铈含量从5.93%改变为4.15%和9.27%；还发现添加成膜促进剂铵盐、氯化物后转化膜耐腐蚀性提高为原来的2.6和5.6倍，其中后者的耐点滴腐蚀能力优于传统铬酸盐转化膜，并且还可将铝合金表面的显微硬度从HV68.8增大至HV389和HV450。
