Chemical Nickel Plating Technology for Product Surfaces

Abstract

When studying how a coating influences the wear resistance of details made of aluminum alloys in production conditions, we conducted a multifactorial experiment. The research has been carried out on the application of nickel-phosphorus coating on the surface of parts made of aluminum alloys, as well as the prefinishing treatment under coating. The parameters influencing the rate of nickel-phosphorus alloy deposition and modes of part surface treatment under coating are selected. Experiment planning was carried out, which made it possible to develop optimal modes of deposition and coating composition for obtaining high quality parameters of its surface: roughness and wear-resistance. It has been established that increasing the concentration of hypophosphite (sodium salt of alkaline metal and hypophosphorous acid) increases the coating formation rate. Experimental studies on wear resistance of nickel-phosphorus coated and uncoated samples have been conducted. The study shows that nickel-phosphorus coated samples provide higher wear resistance under friction conditions in comparison with uncoated samples, and assumes that the uniformity of heterogeneous coating consisting of nickel and phosphorus is due to the uniform fine crystalline structure consisting of regular shape particles (faceted or rounded). The basic principles of chemical coating technology and mechanical engineering technology are used
