    Abstract: A method generates an abrasive wear-resistant layer on a substrate. The layer is formed of particles of a ductile material, in particular Zn, wherein the parameters of the cold spraying process are set such that a comparatively loose laminate having pores is formed by the spray particles. The laminate advantageously and surprisingly exhibits high resistance to abrasive wear (for example by a particle) because the layer can avoid the attack by the particle by plastic deformation and closure of the pores, whereby abrasive removal of the layer is advantageously low. The cold gas-sprayed layer is used as a protective layer against abrasive wear.

  • Patent number: 8216635
    Abstract: Disclosed are a method of forming metal wiring and metal wiring formed using the same. The method includes printing wiring using an ink composition including metallic nanoparticles and dispersants maintaining dispersion of the metallic nanoparticles, performing a first firing process of firing the wiring under vacuum or in an inert atmosphere to suppress grain growth, and performing a second firing process of firing the wiring with the vacuum or inert atmosphere released, to accelerate grain growth. The method of forming metal wiring induces abnormal grain growth by rapidly removing dispersants, capable of inducing the growth of metallic nanoparticles, at a temperature at which the growth force of the metallic nanoparticles is high, in the process of firing the metallic nanoparticles. Accordingly, the metal wiring has a coarse-grained structure containing metallic particles with a large average particle size, and the electrical and mechanical characteristics thereof can be enhanced.

  • Patent number: 8114474
    Abstract: A metallic glass particle layer is applied to aluminum alloy armor and friction stir mixed into the surface in order to embed the material into the armor and to take advantage of its exceptional hardness. An advantage of the invention is that the hard material is an integral part of the armor, included within the body of the armor plate and not merely a surface coating. The advantage of the friction stir process is that it generates relatively low levels of heat and magnetic measurements show that the amorphous phase condition of the metallic glass is not deteriorated. The armor may be tempered to improve properties.
