Implementation of New Commercial Hard Chrome Plating Tooling at
DoD Maintenance Activities

Hard chrome plating is used extensively through the depot operations where applications require hardness, low coefficient of friction (i.e. improves sliding properties), chemical inertness, resistance to wear and corrosion, and an inherent micro crack pattern for the retention of lubricants.  Current hard chromium plating processes used by the depots are labor intensive and time consuming.  The objective of this project is to introduce new electrodeposited hard chrome plating equipment into Department of Defense (DoD) maintenance activities.  This new tooling has many benefits over conventional hard chromium plating equipment, including faster plating rates, improved deposit uniformity, and reduced human exposure to carcinogenic compounds.

The proposed project involves implementation of the new tooling into the Corpus Christi Army Depot (CCAD) plating facility.  At this location, specific parts will be selected from current production activities.  A baseline will be established by monitoring key production parameters (e.g. plating rates, uniformity of deposit, associated production costs).  New tooling will then be fabricated and tested and changes in production parameters will be measured and documented.  A set of production tooling will be provided to CCAD along with written instruction and training.
