Titanium plating technological process for aluminum section bar

Abstract

The invention discloses a titanium plating technological process for an aluminum section bar. The titanium plating technological process is characterized by comprising the following steps of: chemically polishing; chemically removing oil; flushing with clear water; performing surface activation; putting a titanium aluminum section bar which is activated and is flushed with clear water into a liquid consisting of an edible salt, hydrochloric acid and water to perform normal-temperature chemical treatment for treatment time until the liquid generates fierce chemical reaction; putting a pre-plated product into a galvanic bath for plating titanium, and heating a plating solution to 55-60 DEG C, and stirring the electroplating solution, wherein the electroplating solution comprises nickel sulfate, nickel chloride, boric acid, lauryl sodium sulfate, saccharin and a brightening agent, the pH value is kept at 4.0-4.2, current density is 1.2-1.5 A / dm<2> and voltage is 17-19 V; cleaning after plating; drying; and finally packaging.

Description

technical field [0001] The invention relates to the field of aluminum profile manufacture, in particular to a process flow of aluminum profile titanium plating. Background technique [0002] Aluminum has excellent physical properties, such as corrosion resistance, high electrical conductivity, high thermal conductivity, non-ferromagnetic, machinability, formability and recyclability, and my country is a major aluminum-producing country, so in Now in industry and life, it has been widely used, and users have higher and higher requirements for the appearance and color of products.
