We offer a hard chrome plating service using Chromic Acid - Chromium Trioxide Flake from Elementis.
Background: Hard chrome plating, sometimes referred to as functional chrome plating, can be applied in thick layers for heavy industrial applications. It increases wear and corrosion resistance whilst creating a low co-efficient of friction. With abrasion being the most common and destructive wear process found in industry, hard chrome has the potential to solve many problems in pumps, valves, bearings, etc. throughout a wide range of industries; including pharmaceutical, chemical, oil and gas, textiles, printing, food, mining, and countless others.
One application for hard chrome is the refurbishment of worn components where the metal has been lost through wear or been manufactured under size, or, even where there has been an excessive distortion during the hardening process. This application usually requires a thicker deposit and components are pre-chrome ground then a suitable deposit of hard chrome is applied before they are ground back to original sizes and tolerances. Process: Hard Chrome plating is an electrolytic process utilising a chromic acid-based electrolyte. The component requiring plating becomes the cathode and, with the passage of a DC current via anodes, chromium metal builds on the component surface. Applications: Hard Chrome plating has many typical applications, some of which are detailed below:
- Machine spindles and housings
- Pump shafts or rotors
- Hydraulic rods and cylinders
- Any sliding or rotating shafts
