Chrome Hard Plating
Hard Chrome is a very hard surface coating (usually in the region of 950-1150 H.V) with a very low coefficient of friction surface. It is used throughout many industries in a number of different types of applications. Firstly it can be applied to a new component to provide a durable hard wear-resisting coating. Examples of this are -
- Wire wound rods for paper coating
- Seal areas on pump or drive shafts
- Conveyer wear rails and rollers
- Hydraulic rams and cylinders
- Plastic extruder screws
- Print rollers
Another application for Hard Chrome is for the refurbishment of worn components where the metal has been lost through wear or been manufactured undersize or, even if there has been excessive distortion during an hardening process. This application usually requires a thicker deposit and components are pre-Chrome ground then a suitable deposit of hard chrome is deposited before they are ground back to original sizes and tolerances.
