Purpose of the development: For applying a protective, functional coatings on various metal surfaces: copper, brass, beryllium copper, steel, tungsten, aluminum and its alloys, etc.

Recommended application field: Instrumentation, radios, microelectronics, precision electronic engineering.

Advantages over analogues: Reduction of production costs; ease of operation and long-term electrolyte its use in adjusting; deposition technology nickel-boron alloy is a material-and resource-saving; the possibility of damping coatings (Boriding) at low temperature. Has high chemical stability and efficiency. The technology is simple and requires no additional equipment. Replacing dekagidroborata sodium.

The development stage readiness: Introduced in production

Description of the development:
()
Import-substituting technology developed electrochemical deposition from aqueous solutions of electrolytes protective functional coatings for metal- boron coating on printed circuit boards , sensors for the automotive industry . - The rate of deposition coatings for bathrooms: a fixed-type - 25 - 50 microns / hour ; drum and bell-type - 5 - 10 microns / hour ; - Deposition temperature - 20 - 50 ° C; - Microhardness of the coating after thermal treatment (300 ° C) -10 - 13 GPa ; - Transient electrical resistance - 3 - 6 mW ; - Life: nickel-boron ( under dry friction ), 2x10- 7 mm3 Nickel , 8x10- 5 mm3 ; - Adhesion strength Ni-B coatings with aluminum conductor - 10x16 g Corrosion resistant to salt ( sea ) mist condensed atmospheric precipitation , temperature changes and temperature ( thermal cycling ) . Developed coatings not only successfully replace previously used coating of precious metals (palladium, silver, gold ) , but also improve the performance of products. Coatings are characterized by low contact resistance , high hardness , wear resistance, corrosion resistance, good weldability ultrasound and solderability . Has no negative impact on the environment .
