Abstract:
La presente invención propone el uso de un baño electrolítico para electrodepositar recubrimientos compositos metálicos Níquel-Fósforo-nanopartículas de metales con capacidad antibacterial, que inhibe el crecimiento de bacterias como Escherichia coli y Staphylococcus aureus, al menos en 99% sobre su superficie. El método para formular un baño electrolítico que permita obtener recubrimientos antibacteriales contempla los siguientes pasos: a) Adicionar iones P3+ a un baño electrolítico que contenga sales de Ni disueltas, b) adicionar al baño electrolítico nanopartículas de metales con capacidad antibacterial suspendidas en un surfactante catiónico, c) Electrodeposición del recubrimiento composito metálico Ni-P-metal antibacterial aplicando densidad de corriente directa. La oclusión de nanopartículas de metales con capacidad antibacterial en la matriz del recubrimiento le confiere características antibacteriales.
Abstract:
An airfoil is disclosed. The airfoil may comprise a leading edge, a body portion and a trailing edge formed from a high-modulus plating. The body portion of the airfoil may be formed from a material having a lower elastic modulus than the high-modulus plating. The high-modulus plating may improve the stiffness of the trailing edge, allowing for thinner trailing edges with improved fatigue life to be formed.
Abstract:
The invention relates, on the one hand, to a method for producing a medical metallic implant with the properties of antimicrobiality and biocompatibility and, on the other hand, to the metallic implant itself. According to the method, an antimicrobial coating is applied onto a metallic substrate of said metallic implant, the method comprising the steps of arranging said substrate as cathode against a counter electrode in an electrolytic solution containing at least a salt of the metal to be deposited to form the coating, and depositing the coating from the electrolytic solution onto the substrate surface by electrolysis. The essence of the present method is that after an initial pre-treatment of the substrate surface, the electrolysis is performed directly onto the substrate, and said coating is formed as a non-continuous nanostructured coating by pulse current series electrochemical deposition during the electrolysis. The medical metallic implant according to the invention comprises a metallic substrate and an antimicrobial coating, wherein the antimicrobial coating is bound in the form of a plurality of nanostructured microclusters directly to a substrate surface subjected to pre-treatment, and said microclusters are located on said substrate so as to form local galvanic cells when get into contact with an electrolyte.
