Abstract
Przedmiotem zgłoszenia jest kąpiel do galwanicznego osadzania powłoki stopowej Ni-P, stanowiąca wodny kwaśny roztwór siarczanu niklu II, kwasu NMTF i kwasu cytrynowego charakteryzuje się tym, że zawiera sól niklu w postaci siarczanu w przeliczeniu na metal 15 ÷ 18 g/dm3, fosfor w postaci kwasu NTMF o wzorze 1 w ilości 100 g/dm3 i kwasu cytrynowego w ilości 10 g/dm3. Przedmiotem zgłoszenia jest również sposób otrzymywania powłoki stopowej Ni-P na podłożach trudno spajalnych, polegający na jej galwanicznym osadzaniu z kąpieli stanowiących wodny roztwór soli niklu, kwasu NTMF i kwasu cytrynowego charakteryzujący się tym, że osadzanie galwaniczne prowadzi się z kąpieli stanowiącej sól niklu w postaci siarczanu niklu II w przeliczeniu na metal 65 ÷ 85 g/dm3, fosfor w postaci kwasu NTMF (N-tris-metylenofosfonowego) o wzorze 1, w ilości 80 ÷ 100 g/dm3 oraz kwas cytrynowy w ilości 1% wag. odpowiednią mieszaninę tych preparatów dla pH zawartego w granicach 1,5 - 7,5; przy gęstości prądu w zakresie 1,0 ÷ 5,5 A/dm2 przez okres minimum 5 minut.The subject of the application is a bath for galvanic deposition of a Ni-P alloy coating, which is an aqueous acid solution of nickel sulfate II, NMTF acid and citric acid is characterized by containing nickel salt in the form of sulfate calculated as metal 15 ÷ 18 g / dm3, phosphorus in forms of NTMF acid of formula 1 in an amount of 100 g / dm3 and citric acid in an amount of 10 g / dm3. The subject of the application is also a method of obtaining a Ni-P alloy coating on hardly weldable substrates, consisting of its galvanic deposition from baths consisting of an aqueous solution of nickel salts, NTMF acid and citric acid characterized by that the galvanic deposition is carried out from a bath constituting a nickel salt nickel sulphate II calculated as metal 65 ÷ 85 g / dm3, phosphorus in the form of NTMF (N-tris-methylene phosphonic acid) of formula 1 in the amount of 80 ÷ 100 g / dm3 and citric acid in the amount of 1 wt. a suitable mixture of these preparations for a pH in the range 1.5 - 7.5; at a current density in the range of 1.0 ÷ 5.5 A / dm2 for a minimum period of 5 minutes.
