Definitions

  • the surface of the metal alloys are generally subjected to multiple surface treatment processes, followed by deposition of a putty and the exterior coat
  • the multiple surface treatment processes make the overall process of treating the surface and applying the exterior coat complex, time and resource consuming.
  • an alloy substrate of a die-casted metal alloy is received.
  • the die- casted metal alloy is obtained through casting or molding of molten metal alloy in a die or a mold, and then cooling and solidifying are performed to obtain the alloy substrate.
  • the surface of the alloy substrate is porous having multiple pores on the surface.
  • an electrically conductive layer is deposited on the surface of the alloy substrate.
  • the electrically conductive layer is deposited on the surface to cover the surface entirely.
  • the electrically conductive layer may be deposited through a spraying technique or may be deposited manually.
  • the electrically conductive layer may be composed of metal particles and electrically conductive polymers.
  • the die-casted metal alloy 100 has an electrically conductive layer 104 deposited over tine alloy substrate 102.
  • the electrically conductive layer 104 is composed of single or multiple layers of metal particles and electrically conductive polymers.
  • the metal particles include one of aluminum particles, magnesium particles, and titanium particles and the electrically conductive polymers can be one of polylactene, polyphenylenevinylene, poiythienylenevinyiene, polythiophene, poly-3-alkylthiopene, poiypyrrole, polyaniline, polyphenylene, polyphenylene sulfide and polyfuran, and po)y-3,4-ethylenedioxythiopene polystyrene sulfonate (PEDOT).
  • the electrically conductive layer 104 reduces porosity of the surface by allowing the metal particles of the electrically conductive layer 104 to fill the pores and cavities of the surface of the alloy substrate 102.
  • Fig. 3 illustrates the method 300 for treating surface of an alloy substrate, according to an example implementation of the present subject matter.
  • the surface of the alloy substrate generally has large number of pores and cavities that makes the surface uneven and resistant for coating with different materials. Further, the surface is also reactive with gases of the atmosphere and is unstable for holding exterior coats applied on the surface. Therefore, to reduce porosity and reactivity of the surface and make the surface stable for adhesion with exterior coats, a surface treatment process is performed.
  • the exterior coat may be a single layer or multiple layers of paint material or a metallic coat deposited on the alloy substrate for providing smooth and lustrous appearance to the alloy substrate.

Abstract

Des exemples se rapportant au revêtement d'un substrat en alliage sont décrits. Par exemple, des techniques, visant à traiter une surface du substrat en alliage afin d'appliquer sur le substrat en alliage une couche extérieure, consistent à produire un substrat dans un alliage métallique coulé, le substrat en alliage comportant une surface pourvue de multiples pores, et appliquer une couche électroconductrice sur la surface du substrat en alliage. La surface électroconductrice est composée de particules métalliques et de polymères électroconducteurs, et la couche électroconductrice est appliquée de sorte que les particules métalliques remplissent les multiples pores sur la surface du substrat en alliage. Ensuite, un processus d'oxydation est effectué sur la surface pour former une couche d'oxydation sur celle-ci. La couche d'oxydation assure l'adhérence de la surface avec la couche extérieure.
