Definitions
- the invention relates to a method for producing products, in particular decorative veneer, Jewelery, watches, tools, etc.
- a method for producing products involves the formation of a workpiece and in the subsequent application of a layer of the electrolyte suspension on the Surface of the workpiece that contains ultra-disperse diamond-like carbon clusters (see Schebalin A.I., Gubarewitsch W.D., Besedin W.I., Priwalko Ju.N. about diamond-chrome composition layer. Explosion, blow, protection. 1987, issue 17, pp. 111-112, Analog solution and prototype).
- the technical result of this process is the improvement of the operating characteristics of the Product using smaller quantities of the precious product UDA.
- Substances with a tertiary or quaternary ammonium base are used as the cationic substance.
- the electrolytes are based on six-valent chromium, Nikkel, Iron, gold and its alloys with cobalt, nickel, silver and copper, and copper used.
- the layers were at least as thick as possible on the workpieces 50 ⁇ m applied from different electrolytes, especially from electrolytes, which contain ultra-disperse diamond-like carbon clusters (UDA).
- UDA ultra-disperse diamond-like carbon clusters
- the main treatment of the suspension of the ultradisperse was carried out before coating diamond-like carbon clusters in the aqueous sulfuric or hydrochloric acid solution subsequent washing out of the acids in distilled water and the aftertreatment with of the cationic substance for the reduction of the volume capacity and the reloading of the Surface of the particles of the electrolytes.
- substances with tertiary or quaternary ammonium base used.
- the electrolytes were based on six-valent chromium, nickel, iron, Gold and copper used.
- the wear resistance of the layers was determined on a system that realizes friction over hardened steel without lubrication according to the "cylinder with crossing axes" scheme.
- the wear resistance was determined as the size, the amount of the worn material for the determined duration of the tests (the length of the friction path) and the friction pair load (for different types of layers, see table, the absolute friction pair load for chromium, iron was 15 N, for Nickel 10 N, for copper and gold 5 N) is reciprocal.
- the sliding speed was 0.78 m / s
- the length of the friction path was 140 m
- the microhardness of the layers was determined using the DMT-3 device under a load of 100 g and 50 g.
- the wear resistance of the layers was determined on the drum system with an abrasive in the form of cylindrical grains of rubber with glass with a diameter of 8 mm, a length of 10 mm (the samples are checked every 10 minutes).
- the additional exam The exposure of the base (brass) is made using a 10% chlorine copper solution (according to the Redness of the base).
- the visual inspection was carried out using a microscope MBC-2 with 12x magnification.
- the results of the test showed an improvement in the wear resistance of the layer with the treated cluster by 1.7 times compared to the starting cluster.
- the wear resistance of the layer with the starting cluster is 2 times higher than the wear resistance of the gold-cobalt layer without UDA.
- the layer hardness is increased from 2.5 GPa (UDA excl. ) To 3.2 GPa (UDA treated ).
- the invention thus improves the operating characteristics of the products.
- the coating method according to the invention for use other workpieces, especially their surfaces.
- Both can metallic and non-metallic workpieces, which are treated electrolytically in acids can be coated.
- the procedure for eyeglass frames, Household items, plastics or the like. Are used.
- the invention can be used in the manufacture of decorative veneer, jewelry, watches, tools and others.
