Resumen:
Un grupo de investigación búlgaro que trabaja en el campo de sistemas autónomos y tecnologías de la información y comunicación ofrece una nueva tecnología de niquelado químico de ejes metálicos de máquinas de extrusión de películas mediante el uso de nanopartículas que mejora la dureza y resistencia al desgaste. El grupo de investigación ha seleccionado una formulación adecuada de la solución y ha obtenido las concentraciones óptimas de los componentes y el porcentaje exacto del tiempo para conseguir revestimientos del espesor buscado. El revestimiento de níquel que incorpora nanopartículas sigue la topografía del sustrato. Otra ventaja son los trabajos mínimos de acabado que se necesitan. El grupo de investigación busca empresas con el fin de establecer acuerdos de licencia.

New technology offered under license for chemical plating the surface of a metal shaft with nano-particles
Summary:
A Bulgarian research team is working in the field of autonomous systems and IT communication technologies. The researchers offer a new technology for chemical plating the surface of the shaft extruding a film with nano-particles improving the hardness and wear resistance. The researchers are looking for companies interested in the technology under a license agreement.
Description:
The Bulgarian research team is working for many years in the field of autonomous systems and ITC technologies. They would like to offer a new technology for renewing the shafts of the machine equipment extruding a film with nano-particles over the top surface of the shaft. On this way they could improve the hardness and wear resistance of the coating with thickness up to 25 -Y-micro;m at 250 -Y-micro;m chrome plating. There have been experimental studies of Al2O3, SiC and nano diamonds with 4-20 nm. A suitable formulation of the solution is selected and the optimum concentrations of the components and exact ratios of time are obtained to achieve the desired coating thickness. It has been shown that in the ground of a desired smoothness steel base (which process is known and well utilized), the small chemical nickel coating incorporating nanoparticles follows the topography of the substrate and minimal finishing works are necessary. Methods are developed for testing the hardness and chemical durability of nickel coatings including nanoparticles.

The main goal is the creation of industrially applicable technology and the design of a relevant technological line for laying of coatings with high mechanical wear-resistance and surface-smoothness for renovation of the working area of shafts for extruding sheet material (PVC, Plexiglas, other plastics) by laying and polishing of new types of highly wear-resistant coatings based on ultra disperse nickel coatings with, nanodispersoids and/or nano-particles included.
Extruding (pressing by pushing) of sheet material from non-metal materials (Plexiglas, PVC, other plastics) is widely used in households. Gifts, flowers, sugar and chocolate packing is made from thin aluminum sheets. Thin Plexiglas sheets are used to make pack-boxes, and thick nylon sheets are used to make bags, raincoats, etc.
The vast amount of production of smooth sheets of various sizes from these materials has brought to the development of technologies in which the material is pressed and pushed out (extruded) between shafts of various diameters (100 - 500 mm) and various lengths (1 - 3 m). The shafts are chromed, have very narrow tolerances of diameter size and very high degree of smoothness by polishing.
With the time and at high production rate shafts age, their surface wears out, and sometimes scratches appear in incidents. All this makes the shaft surface not precisely circular and even. Because of a new shaft´s very high price, renovation of the defected shaft is applied in such cases by applying a new coating and polishing it to mirror shine.

The research team seeks companies for signing a license agreement.They would like to sell the new technology to interested companies.
Advantages and Innovations:
The resulting coating has improved hardness and wear resistance, and its production does not harmful pollute the environment.
The main advantage is the use of nano-particles in this coating.
The other innovation is that a small chemical nickel coating incorporating nano-particles follows the topography of the substrate and minimal finishing works are necessary.
Stage of Development:
Field tested/evaluated
IPs:
Patents granted
CommeR Statunts Regarding IPR Status:
3 National Patents
