Definitions
- the invention relates to a method for the production of products, in particular decorative veneer, jewelry, watches, tools, etc.
- a method for producing products which consists in the formation of a workpiece and the subsequent application of a layer of the electrolyte suspension to the surface of the workpiece which contains ultradisperse diamond-like carbon clusters (see Schebalin AI, Gubarewitsch WD, Besedin WI, Priwalko Ju.N. on diamond
- the presence of particles of the ultradisperse diamond-like carbon clusters (UDA) chemical groups predominantly acid origin on the surface causes a specific behavior of the particles of the disperse phase in the electrolytes with different pH values.
- the particles of the UDA are given a negative charge in the acidic medium (pH ⁇ 7), which characterizes the majority of the electrolytes of chromium plating, nickel plating and a few others, which also hinders their functionality on the surface of the cathode has a negative charge.
- the inclusion of the particles in the layer is immaterial.
- the nature of the surface of the UDA particles favors their functionality on the cathode.
- Substances with a tertiary or quaternary ammonium base are used as the cation-active substance.
- electrolytes based on six-valent chromium, Nikkei, iron, gold and its alloys with cobalt, nickel, silver and copper, and copper are used as the electrolyte suspension.
- the layers were applied to the workpieces with a thickness of at least 50 ⁇ m from different electrolytes, in particular from electrolytes that contain ultradisperse diamond-like carbon clusters (UDA).
- UDA ultradisperse diamond-like carbon clusters
- the main treatment of the suspension of the ultradisperse diamond-like carbon cluster in the aqueous sulfuric or hydrochloric acid solution followed by washing out the acids in distilled water and the aftertreatment by means of the cationic substance for the reduction of the volume capacity and the recharging of the surface of the particles of the electrolytes.
- the latter substance substances with a tertiary or quaternary ammonium base were used.
- the electrolytes based on six-valent chromium, nickel, iron, gold and copper were used.
- the wear resistance of the layers was determined on a system that measured the friction over a hardened steel without lubrication according to the “cylinder with intersecting
- 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 tested on the drum system with an abrasive in the form of cylindrical grains made of rubber with glass with a diameter of 8 mm and a length of 10 mm (inspection of the samples every 10 minutes).
- the additional check of the exposure of the base (brass) is carried out using a 10% chlorine copper solution (after reddening the base).
- the visual inspection was carried out using a microscope
- 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 other workpieces, in particular their surfaces. All metallic and non-metallic workpieces can be treated electrolytically in acids can be coated.
- the method can be used for eyeglass frames, household items, plastics or the like. If necessary, a further pretreatment is necessary, for example in the case of plastics, in order to deposit a conductive layer on the respective objects beforehand.
- the invention can be used in the manufacture of decorative veneer, jewelry, watches, tools, etc. be used.
