Track Link Tratamiento superficial Breve introducción

The excavator track link (cadena de pista) is an important accessory of the excavator. It help the huge excavator can “walk”.
To make sure the high quality of excavator track link, we may do some special surface treatment. here are the short introduction for your ref.

Tratamiento térmico
In the heat treatment equipment, various auxiliary media are used at high temperature to improve the organizational structure of parts and improve various physical properties.

Shot peening
As a kind of surface treatment, steel shot with a certain diameter is sprayed on the surface of excavator track link parts as required to form uniform small pits, so as to improve the surface fatigue strength of the chain.

Bluish
After the parts are heated to a certain temperature, they are cooled by chemical aqueous solution and saponified to make the surface color of the parts appear blue. El track chain assy for excavator after bluing treatment has beautiful appearance and anti rust effect.

Phosphating
Immerse the parts in the phosphating solution at a certain temperature to form a phosphating layer on the surface of the parts, which can make the surface color of the parts appear black or gray, improve the beauty of the chain and achieve the purpose of anti-corrosion at the same time. These phosphating solutions can be recycled and have less environmental pollution.

Plate with nickel
The method of electroplating or electroless nickel plating is adopted to form a nickel ballast layer on the surface of parts. The nickel coating can not only beautify the chain, but also prevent corrosion. Zhenni chain – generally used in open air.

Galvanized
The galvanizing layer is formed on the surface of parts by electroplating or chemical galvanizing. The galvanizing layer can not only beautify the chain, but also prevent corrosion. Galvanized chains are generally suitable for outdoor occasions.
