表面涂层

The silane coupling agent enwrapped in the surface of copper powder was studied by infrared spectral analysis technology. The conductive property of coatings was examined.

用红外光谱分析技术研究硅烷偶联剂在铜粉表面的接枝情况，对涂层的导电性能进行测试，确定了偶联剂的处理工艺。

Smooth microregion,craters and cracks appeared on the surface.The γ′ phase manifolded and there was no visible thermal stress.

原因在于电子束辐照处理的涂层氧化后表面形成了更加完整的Al2O3保护层，同时γ′相的增加也有利于其耐氧化性能的提高。

Desirable Knowledge of surface treatments such as: paint, coat galvanising, metalized coating, etc.

IF2005M, is the basis of the No Residue Technology, is a flux chemistry that completely evaporates during the soldering process eliminating all problems involved with cleaning or rosins IF2005M is one of the first no clean fluxes ever approved according to MIL-F-14256F and has now a real field experience in high sensitive electronic environments for more than 10 years. The performance on pretinned, bare copper and organic coated surface is excellent.

IF2005M免清洗助焊剂，是免清洗技术的经典之作，它是一种在焊接过程中可以完全挥发掉的助焊剂，从而可免除清洗工序，并解决了传统松香型助焊剂所产生的全部问题，IF2005M是首批通过美国军标MIL-F-14256F认证的环保型助焊剂之一，在对环境比较敏感的电子领域已有十几年被应用的历史，实践证明，它在镀锡、裸铜以及有机涂层的表面性能上有极佳的表现

Element Ti segregates at the surface of Al〓O〓 particles after brazing.

焊后涂层中活性组元Ti在Al〓O〓陶瓷表面偏聚。

Finer surface finishes also may be needed to eliminate unnecessary stress concentrations, especially in areas of machined radii or undercuts.

起光滑表面作用的涂层还应当避免不必要的应力集中，尤其是机加工倒角或内切槽。

RESULTS: The surface feature of each sample showed globular granule with caky structure and air pore. The crystal structure of group A, B, C mainly showed characteristic absorption band of Ca102(PO4)6 which degraded while antimicrobial content increased. Except Ca102(PO4)6 and CaZr (PO4)2, Na6CaP2O9 also appeared in group D.

结果：4组涂层材料镜下表面形貌相似，均为球状颗粒中夹杂&饼状&结构及气孔；A、B、C组晶相主要呈现羟基磷灰石主要成分Ca102(PO4)6的特征峰，且随抗菌剂含量上升，峰值降低。D组除主要呈现Ca102(PO4)6的特征峰外，还出现CaZr(PO4)2、Na6CaP2O9等新相。

The properties are also studied, which testified that firm load technology for metallic substrate catalyst has a board foreground in automobile catalyst application.

研究证明本论文研究的以金属表面预处理为主体的涂层牢固负载技术，能够广泛应用于各种类型的机动车尾气催化净化剂中。
