Development of technologies and equipments for the production of nano-structured layers

The essence of the method is that we do the electroplating by galvanization but not using the conventional direct current but with the so-called pulse-current, when the current changes periodically when a very short (of the order of a millisecond duration) big cathode current impulse is followed by a current-free relaxation or change of polarities. We analyze the most important physical attributes of the coatings produced this way with the conventionally structured materials.

For the abovementioned production of nano-structured materials a conventional direct current power-supply cannot be used as a power source. We need to develop such an equipment that is capable of the emission of the mentioned different current signature shapes.
The conventional galvanic technologies, especially the processes used for the production of highly complicated printed-circuits also need more and more intelligent power sources.

The equipment fit for the abovementioned purposes mean in several respects similar development work so we have targeted a modular family of equipments from which for all the purposes an appropriate power source can be chosen. After the successful completion of the project a member of the Consortium plans to produce the developed equipments in a industrial quantity. With the electrochemical impulse technology the nano-structured and the multi-layers can be produced at least 30% lower costs with greater purity and steadier layer.

For the electrochemical production of nano-structured materials a conventional direct current power-supply cannot be used as a power source. We need to develop a new type of power source with the connected intelligent control device. During the development of the power source - keeping in mind a wide spectrum of usability - the needs of galvanizing of highly complex printed circuit print and bore and newer types of galvanizing objectives are also taken into consideration as well.

Planning and producing for the galvanization of conventional and printed circuits a semi-duty sized 2x40 A current carrying capacity power source with modular interconnectivity that is suitable for direct current power generator feeding of galvanic electrolytes that can be interconnected with an intelligent control device and with this digital unit it is possible to choose the mode of operation, galvanizing period and amperage adjustment and the keeping track of the volume of the electric charge going through the galvanic bath. The usability of the equipment for galvanizing and for the production of highly complex circuit diagram plates are checked in semi-industrial equipments (1st stage).

In parallel with the previous objective we produce a laboratory power-source for the production of nano-structured non-equilibrium electrochemical layers (amperage is at least 5 A, voltage is 15 V, minimal switch-on time is 1 ms, 2nd stage). With the help of the power-source nano-structured (mainly nickel) layer is produced and with this we test the usability of the equipment produced. We analyze the main physical characteristics of the layers produced so and we compare those with the materials of conventional composition. We produce the technological description of the layer’s industrial production (4th stage).

A laboratory sized 10 A current carrying capacity stepped pulsing and polarity-changing current power-source is produced with intelligent control that is capable of changing the current capacity in accordance with the program given, metering ampere-hours and with this controlling delivery systems and performing the monitoring functions needed (3rd stage). With the power-source produced a nono-structured multi-layer is produced. We analyze the main physical characteristics of the layers produced so and we compare those with the materials of conventional composition. We produce the technological description of the layer’s industrial production (5th stage)

We make and industrial size 100 A current carrying capacity new type, modularly expandable power supply that has better efficiency and smaller than the current equipments. A new type of galvanic layer is produced by the device (6th stage).
A newer, 100 A current carrying capacity power supply is produced. An intelligent control device is produced capable of operating parallel the two 100 A power supply and can be used for modern galvanizing technologies (7th stage).
