Description
Vynález ee týká elektrolytu pro katodická vylučováni slitiny niklu β wolframem z vodných roztoků·The invention relates to an electrolyte for cathodic deposition of a nickel β-tungsten alloy from aqueous solutions.
V odborná literatuře je popeáne řade elektrolytů,' která obsahuji rozpustné sole niklu, například síran;, sulfosalicylan, fluoroboritan a aulfamát. Oo těchto elektrolytů ea wolfram přidává ve formě wolframenu eodného* K zamazaní vzniku nerozpustného wolfratnanu nikelnatého ea do lázně jeětě přidávají komplexotvorné látky,1 které udržuji wolfram ve formě rozpustné komplexní sloučeniny* Oako komplexotvorné látky jaou uváděny karbonové kyeeliny, například kyselina citrónová,· vinná. Jantarová nebo sulfokarbonové kyeeliny, například kyselina eulfoaalicylová. Tyto látky Jaou nestabilní a během elektrolytického děje dochází k jejich rozkladu* Vzniklá rozkladná produkty jsou příčinou vysokého vnitřního pnuti slitinových povlaků* Pouze kyselina aulfoaalicylová ja atabilni, ale vzhledem k tomu, ža aa solemi wolframu tvoři velmi slabý komplex, je možná vyloučit slitiny nikl-wolfram pouze a nízkým obsahem wolframu ve slitině, a to maximálně S % hmotnosti. Při vyěěim obsahu wolframu aa vylučuji povlaky technicky nepoužitelná, protože jaou velmi křehká a samovolně praskají.A number of electrolytes which contain soluble salts of nickel, e.g. Oo these electrolytes ea tungsten added as tungstate eodného * K smeared form insoluble wolfratnanu nickel EA into the bath Jeet added complexing agents, one that hold tungsten in the form of a soluble complex compound * Dako complexing agents Jaouich mentioned carbon kyeeliny, e.g., citric acid · tartaric acid. Succinic or sulfocarbon acids, for example eulfoaalicylic acid. These substances are unstable and decompose during the electrolytic process. * The resulting decomposition products cause high internal stresses of the alloy coatings. * Only sulphoaalicylic acid is unstable, but since tungsten aa forms a very weak complex, nickel alloys can be excluded tungsten only and low in tungsten in the alloy, at most S% by weight. At a higher tungsten content, the coatings are technically unusable because they are very brittle and spontaneously crack.
Uvedené nevýhody Jsbupodle vynálezu odstraněny elektrolytem pro katodické vylučováni slitiny nikl-wolfram z vodného roztoku. Podstata vynálezu spočívá v tom, že elektrolyt sestává z vodného roztoku,' obsahujícího na 1 000 g vody 50 až 500 g nikelnatých soli,' 1 až 50 g wolframanu eodného, 1 až 100 g 1,8-dihydroxynaftelan-3,<6-dieulfonové kyseliny, 1 až 50 g halogenldu, 0,01 až 0,5 g lonogenního smáčedla a 10 až 200 g hořečnaté soli kyseliny aulfosalicylové. Nikelnatými solemi sa rozumí síran, fluoroboritan, aulfamát nebo sulfosalicylan. I,i8-dihydroxynaftalen-3,6-diaulfonová kyselina může být nahrazena Její sodnou, draselnou nebo hořečnatou aoli* lonogennim emáčedlem aa rozumí aulfojanteren sodný nebo dlleopropylnaftalanaulfonan aodný.These disadvantages have been eliminated by the electrolyte for cathodic deposition of the nickel-tungsten alloy from the aqueous solution. SUMMARY OF THE INVENTION The electrolyte consists of an aqueous solution containing, for 1000 g of water, 50 to 500 g of nickel salts, 1 to 50 g of sodium tungstate, 1 to 100 g of 1,8-dihydroxynaphthalate-3, <6- dieulfonic acid, 1 to 50 g of halide, 0.01 to 0.5 g of ionic surfactant and 10 to 200 g of magnesium aulfosalicylic acid. By nickel salts is meant sulfate, fluoroborate, sulfamate or sulfosalicylan. N, 18-dihydroxynaphthalene-3,6-diaulfonic acid may be replaced by its sodium, potassium or magnesium aoli * ionic surfactant, and is understood to mean sodium sulfonate or di-propyl naphthalanine sulfonate.
Výhodou elektrolytu podle vynálezu je, ža umožňuje vylučovat povlaky alitin nikl-wolfram a nízkým vnitřním pnutím a a vysokým obsahem wolframu va slitině, takže je možno táto slitiny použit Jak pro galvanoplaatiku, tak i pro renovaci strojních součásti.The advantage of the electrolyte according to the invention is that it makes it possible to deposit alitin nickel-tungsten coatings with low internal stresses and a high tungsten content in the alloy, so that the alloy can be used for both electroplating and machine parts renovation.
Vynález Je objasněn ve čtyřech příkladech provedeni, kterými věak neni jeho rozsah omezen ani vyčerpán.The invention is illustrated in four exemplary embodiments, which are not to be limited or exhausted.
Elektrolyty uvedené v příkladě 1 až 4 byly použity k pokováni lopatky turbokompresorů, zhotoveni forem na lisováni plastických hmot a k renovaci opotřebených rotačních části kompresorů.The electrolytes listed in Examples 1 to 4 were used to coat the turbocompressor blades, make molds for molding plastics, and to renovate worn rotary compressor parts.
