We provide a technology or a technological process for applying of nanomodified electrolytic coating of chromium and nickel that provides energy efficiency (lower power consumption), higher micro hardness, corrosion and wear resistance at dry friction of steel parts.

The proposal to our potential customers is to significantly improve the properties of the produced or used metal items by a nickel or chromium plating containing nanoparticles, made by a patented and innovative company technology.

 

SERVICE CHARACTERISTICS

• Uniqueness: Patented and unique mass conversion made out of laboratory.
• Reliability: In essence, the tehnology guarantees increased resistance, working capacity (labour resource) and complete properties of the processed items at different operating conditions and mechanical depreciation.
• Innovation: Thanks to the nanoparticles’ properties our customer gets the opportunity to dramatically improved the production's effectiveness at relatively low additional investment value that additionaly determines the choice of the 'NANOTECHNOLOGIES-BUSINESS INNOVATION' Ltd. technology.

 

Availability and nature of the technology

The offered service is available to all industrial users, including small and medium-sized enterprises disposing of an adequate basis and guarantees better performance compared with elements untreated by this innovative processing.

The essence of technology lies in the use of nanoparticles which have exclusive advantages regarding the impact of various external forces on the metal components during the application of such coverage.

 

Technology advantages

• The time for application of a conditional unit coverage is reduced to 2 times in other equal conditions - concentration and temperature of the electrolyte and the current power.

 

• In addition, as the proposed coverage is much better than traditional, instead of the traditional coating thickness of 20 microns it can be used with our thickness of 10 microns, which represents an additional saving of chromium, energy and labor.

The resultant micro hardness of the coating is about 3 times greater than this one of the pure chromium (Cr) coating and 9 times higher than that one of the steel also.

•    Over 5 time higher values of the wear resistance as compared with those of the pure chromium coating

 

•    Significantly improved corrosion resistance.

2. Advantages of materials with nanomodified electrolytic nickel-plated coating applied:

 

•    The nickel-plated coatings modified with nanocatalyser have a layer thickness of 3 to 10 μm depending on the conditions of the nickel plating.

 

•    The resultant micro hardness of the coating is about 2 times greater than this one of pure nickel (Ni) coating and significantly higher than that one of the steel also.

•    Higher values of wear resistance. The wear is considerably less than at a coating made without the addition of nanocatalyser.

The following figures show topographical images of the surface of samples after 500 m of friction:

It shows that the corrosion rate depends on the concentration of nanoparticles in the coating.

SUMMARY OF THE TECHNOLOGY ADVANTAGES
Finally, we argue that the technology of 'NANOTECHNOLOGIES-BUSINESS INNOVATIONS' LTD. owns the exclusive properties proved of more efficiency, endurance and overall fitness of the processed elements and manages to adapt to industrial implementation at a relatively much lower price appreciation.
