Beschreibung
Zusammenfassung:	FIELD: chemistry.SUBSTANCE: invention relates to the field of application of composite nickel-phosphorus coatings on steel details by a method of chemical precipitation A solution contains, g/l: nickel dichloride 10-15, succinic acid 12-15, sodium fluoride 2-3, sodium hydroxide 4-6, sodium hypophosphite 17-20, copper-intercalated potassium polytitanate 6-10, remaining part - water.EFFECT: invention makes it possible to obtain composite nickel-phosphorus coatings, which have an increased wear resistance and low friction coefficient, as well as makes it possible to increase the strength of adhesion of the coating with the base.2 tbl Изобретение относится к области нанесения композиционных никель-фосфорных покрытий на стальные детали методом химического осаждения. Раствор содержит, г/л: никеля дихлорид 10-15, янтарная кислота 12-15, натрия фторид 2-3, натрия гидроксид 4-6, натрия гипофосфит 17-20, интеркалированный медью полититанат калия 6-10, остальное - вода. Изобретение позволяет получить композиционные никель-фосфорные покрытия, обладающие повышенной износостойкостью и низким коэффициентом трения, а также позволяет увеличить прочность сцепления покрытий с основой. 2 табл.
