DISGO Metal Surface Treatment Technology

The common metals in life are more active in oxidation reaction, and once the reaction occurs, the original mechanical properties of the metal will be lost. In order to maintain the mechanical properties of the metal for a longer time, the metal surface is generally treated accordingly. Metal surface treatment technology is the use of chemical, electrochemical, physical, mechanical and composite methods to make the metal surface form a different organizational structure from the metal itself, in order to resist oxidative corrosion in humid, high temperature, acidic and other environments, so as to extend the service life of the metal itself. However, the metal surface treatment does not change the properties of the metal itself, but adds a special protective film to the metal surface, so that the metal after surface treatment has different characteristics such as wear resistance, corrosion resistance, or high temperature resistance.

DISGO is a special metal surface treatment technology. Disco is completely environmentally friendly and complies with the EU ROHS (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive). DISGO is a chromium-free ultra-thick film corrosion resistant surface treatment technology further developed for the phenomenon of hydrogen embrittlement caused by RUSPERT processing. After the surface treatment of the product, due to the protection of high chromium-free chemical oxidation solution, the occurrence of hydrogen embrittlement is avoided.

DISGO Metal surface treatment technology offers the following features:

1, High Corrosion Resistance —— salt spray test reached more than 2000 hours

2, No Hydrogen Embrittlement —— no pickling process

3, Low Temperature Treatment —— -200℃ temperature treatment process will not cause material changes

4, Drug Resistance —— strong acid rain resistance

5, Heat Resistance —— heat resistance to 300℃

UNITEK products use DISGO surface treatment technology. The treated fastener products are resistant to corrosion and high temperature.
