Purpose of the development: - increasing the durability of machine parts and mechanisms; - increase of wear resistance of means of the control of geometrical sizes; - protection of the working surfaces of molds and dies used to form plastic products; - restoration of the dimensions of the working surfaces of worn out precision friction pairs; - increasing the biocompatibility of implants used in traumatology and orthopedics, cardiac surgery.

Recommended application field: Machine building, tool industry, medicine.

Technical characteristic: Parameters of deposition process of diamond-like carbon films: - average power consumption: 25 kW / h; - the maximum size of the sprayed product: 200-200-300 cubic meters; - average load in one process: 6-50 pcs.; - cost of one process: 60-100 cu; - duration of those. process: 1,5-3,5 h; - deposition temperature: 30-90 ° C. Characteristics of diamond-like carbon coatings: - thickness: 0.05-5.0 m; - microhardness: 30-85 GPa; - temperature resistance: 350-400 ° C.

Advantages over analogues: These coatings have unique mechanical, chemical and thermal characteristics. The combination of a low coefficient of friction and high wear resistance makes it possible to increase the life time of precision pairs of friction of machines and mechanisms by many times. Metallic implants with a diamond-like coating demonstrate high biocompatibility. Unlike other coatings, they do not cause blood coagulation, serve as an effective barrier preventing the diffusion of metal ions, and can be effectively used for implant coatings that contact bone and soft tissues of the body.

The development stage readiness: Introduced in production

Technical and economic effect: Increase the service life of products in 1,5-5 times.

Description of the development:
()
The technology for obtaining diamond-like carbon coatings consists in using the pulse cathode-arc discharge method in vacuum and condensation of high-speed plasma fluxes of carbon and is based on the use of pulsed carbon plasma generators with graphite electrodes. High energies and the degree of ionization of the plasma flow ensure good adhesion of the applied coating to the material of the molds. The use of diamond-like carbon coatings improves the performance of foundry molds and thereby reduces the percentage of defective products, increases the working life of foundry equipment, and also replaces the costly, energy-intensive and environmentally damaging galvanochemical processes traditionally used in chromium coating to protect molds.
