CHROME GALVANIZING TREATMENT: HARD CHROME

Chrome plating –is a proven method that allows to use the details successfully in different conditions. Chromium electroplating, and it is the coating of metal with hard chrome, is characterized by extreme hardness and high resistance. Actually, the phrase "hard chrome", which is used in industrial terms, captures the essence of chromium. The highest rates of endurance and wear resistance are achieved by the electroplating exactly.


BASIC CHARACTERISTICS OF THE COATING:

  1. Hardness and wear resistance - in conditions of:
    • dry friction;
    • friction during rotation or under a high pressure;
    • abrasive preparations;
    • at high temperatures.
  2. Corrosion and thermal resistance. - Chrome has a good grain metal structure, therefore a greater resistance to oxidizing agents and chemicals and high temperatures that are required for the metal oxidization.  Hard chrome resists the heat up to 427 Celsius degrees.
  3. Low friction coefficient. - The chrome can be ground or polished to a high end finish.

Electroplated chrome makes possible the successful use of the hard chrome:

1. Components machining molds, heating probes, ejector pins

2. The inspection process, measuring gauges, sliding gauges, supporting clamps.

3. Cutting tools, drills, taps.

4. A process equipment, compactors, conveyors, extruders, nozzles, fittings.
