HARDCHROME

 
 
 

TECHNICAL HARDCHROME AND ITS ADVANTAGES

 
The hard chrome plating, is an electrolytic process that aims to confer the coating of mechanical properties of hardness and wear resistance to the workpiece, wich brings advantages to the industrial sector, seen to ensure greater durability, resistance to chemical action, to Corrosion and a absence of oxidation at elevated temperatures.

Technical information

HARDNESS – High between 68/70 Hr (Rockwell), 900/1000 Hv (Vickers) average, Mohs 8.5 scale;

FRICTION – low coefficient with high sliding power, no need to use lubricants due to not generating adhesion of particles;

WEAR – Hard chrome coated material resists about 5 to 8 times more than without hard chromium;

RESISTANCE – Absence of oxidation at high and low temperatures, corrosion, chemical action, among others;

THERMAL CONDUCTIVITY – 93W mK.
