• ZINC PHOSPHATING
• ELECTROLYTIC CADMIATING OF STEELS
• ELECTROLYTIC NICKEL PLATING OF STEELS

Zinc phosphating It's a galvanic process that involves applying a layer of zinc phosphate to the surface of a steel piece. This layer provides corrosion protection and improves the adhesion of paints and other coatings.

The zinc phosphating process involves immersing the piece in an acid solution containing zinc salts and phosphates. During the immersion, the steel is cleaned and prepared for the subsequent application of the zinc phosphate layer.

After immersion, the piece is washed thoroughly to remove any residues of the acid solution and then immersed in a zinc phosphate solution. This solution reacts with the steel to produce a layer of zinc phosphate on the surface of the workpiece.

The last step of the process consists in washing and drying the phosphate piece. The end result is a steel piece with a zinc phosphate layer that offers corrosion protection and improves the adhesion of subsequent coatings.

Zinc phosphating is used in a wide range of industrial applications, including automotive, construction and electronics. It is a very widespread galvanizing technology and also used in combination with other galvanic treatments to offer even more effective protection against corrosion.

Electrolytic cadmium plating Steel plating is a galvanization process that involves applying a layer of cadmium to the steel surface. This cadmium layer provides protection against corrosion and improves the aesthetic appearance of the piece.

The electrolytic cadmating process involves immersing the piece in a solution containing cadmium salts and a reducing agent. During the immersion, the steel is cleaned and prepared for the subsequent application of the cadmium layer.

After immersion, the piece is placed in an electrolytic bath containing dissolved cadmium. An electric field is applied across the bath, causing a uniform layer of cadmium to be deposited on the surface of the part.

The last step of the process consists in washing and drying the cadmium-plated piece. The end result is a steel piece with a cadmium layer that offers protection against corrosion and improves the aesthetic appearance of the piece.

Electroplating of steels is used in a wide range of industrial applications, including automotive, aeronautics and electronics.

Electrolytic nickel plating Nickel plating is a galvanizing process that involves applying a layer of nickel to the steel surface. This nickel layer provides protection against corrosion, improves the aesthetic appearance of the piece, and can also improve its mechanical properties.

The electrolytic nickel plating process involves immersing the piece in a solution containing nickel salts and a reducing agent. During the immersion, the steel is cleaned and prepared for the subsequent application of the nickel layer.

After immersion, the piece is placed in an electrolytic bath containing dissolved nickel. An electric field is applied across the bath, causing a uniform layer of nickel to be deposited on the surface of the workpiece.

The last step of the process consists in washing and drying the nickel-plated piece. The end result is a steel part with a nickel layer that offers corrosion protection, improves the aesthetic appearance of the part and can also improve the mechanical properties of the part.

Electrolytic nickel plating of steels is used in a wide range of industrial applications, including automotive, aeronautics and electronics. Additionally, nickel has magnetic and wear-resisting properties that make it ideal for some specific applications.
