Scotland, the birthplace of British textile industry, witnessed a fast development of shoe-making industry in the late 18th century. In the 19th century when aristocratism still prevailed in Britain, FloydTill , the founder of FSL and famous shoe-maker took a bold action and saluted a selection of simple but colorful new shoes. FSL featured casual, simple and relaxing style with a touch of elegant in it, brazing news trails in the traditional shoe-making industry, which was dominated by gentleman shoes of dull color.

苏格兰是英国针织业的诞生地，18世纪后期，苏格兰的制鞋业迅猛发展。19世纪的大不列颠还是贵族绅士风格盛行的地带，创始人FloydTill，著名的制鞋师大胆地启用了简单线条勾勒以及多样色调设计出了一系列新款式样，FSL设计风格休闲、洗练、轻松，且遗留淡淡的贵族气息，打破当时绅士鞋传统、严肃、色调单一的模式，在19世纪英国制鞋业掀起了轩然大波。

The results showed that the three kinds of prealloy powder have excellent low temperature sintering characteristics and good wear resistance. They have excellent physical and mechanical characteristics close to ultrafine cobalt and imported prealloy powder, good retention to diamond and excellent bonding momental for high frequency brazing. At one time, they have lower cost and reduced dosage.

结果表明：三种预合金粉末有着优良的低温烧结性能和耐磨性，表现出接近于超细钴和相当于国外代钴粉末的优良的物理、机械性能，对金刚石把持力高；具有高的高频钎焊结合力矩；粉末成本较低，用粉量可降低。

In this article, three kinds of prealloy powder were developed by water atomization method. The base attribute, pattern, phase composition, differential thermal analysis of powder were researched. Sintered density, hardness, bend strength, Young's modulus were researched as hot pressed sintering temperature changing. By using abrasive wearing equipment upbuilt by the authors, the wear resistance were determined. Green-pressing density, simulated green-pressing strength and bonding momental of high frequency brazing were assayed. SEM corrosion structure and SEM appearance of fracture were observed.

本文采用水雾化法开发了三种预合金代钴粉末：对粉末的基本属性、形貌，粉末的相组成，粉末的差热性进行了分析研究；测定了它们的烧结密度、硬度、抗弯强度、弹性模量随热压烧结温度变化的规律；采用作者自行建立的磨料磨损试验方法，测定了它们的质量磨损百分率；测定了它们的冷压生坯密度、模拟生坯强度以及高频钎焊的结合力矩；观察了热压烧结SEM腐蚀组织和SEM断口形貌。

In the interfacial layer near to SiC, elements Pd and Ni preferentially diffused to SiC and resulted in the reaction products of Pd-Si phase, Ni-Si phase and graphite. In the reaction zone further away from the SiC, mainly elements Cr and V in the brazing filler participated in the interface reaction, and formed Cr-C, Cr-Si, Cr5Si3C. In the central part of the joint, the matrix was composed of Pd-Si, Ni-Si and V-Si phases, on which some blocky carbides V2C, Cr23C6 distributed scatteringly.

MPa。微观分析表明，在靠近SiC的界面反应层中，主要是Pd和Ni优先与SiC反应生成相应的Pd-Si相，Ni-Si相和石墨；接头中在离SiC稍远的区域，主要是Cr和V与母材扩散进入钎缝且未与Pd和Ni反应的C和Si发生反应，生成Cr-C， Cr-Si， Cr5Si3C 等相；钎缝中心区的基体由Pd-Si，Ni-Si和V-Si相组成，其上弥散分布着块状碳化物V2C和Cr23C6。

The differences in the diffusion ability of Si in the common and rapid solidifiable Al-Si brazing metal were preliminarily investigated and discussed.

实验结果表明，普通钎料和快冷钎料中Si元素在母材基体中的扩散过程基本相同。
