Description

Chromium (VI) oxide (CrO3) is a highly toxic compound which has mutagenic and carcinogenic properties. It is also harmful to water resources and the environment in general. Due to its high hardness and corrosion resistant characteristics, it is widely used in electroplating applications, with the automotive industry being one of the biggest consumers of chromium plated parts. In striking contrast to hexavalent chromium, chromium (III) oxides are nontoxic and therefore a candidate for replacing chromium (VI). Since chromium (III) plated products could not satisfy requirements of customers so far, it has not been applied in plating processes on a broader scale.
The novel plating line is appropriate for the application of both, chromium (III) and chromium (VI) oxides in order to ensure supply capacities which are crucial for continuity of the company in the highly competitive automotive sector.

Advantages


  • Reduction of electroplating sludges by 52.3%

  • Considerable annual reduction of material consumption (nickel: -3.3 tons, nickel sulphate: -35.65 tons, lime milk: 45.5 tons)

  • Replacement of fossil fuel (natural gas)

Innovative aspects (ecologic, social and economic)

BIA proved an environment friendly chromium (III) plating process for the first time on a larger scale. Resulting products are currently under examination by customers in long term quality checks (field tests). PFOS, which is toxic to mammals, was replaced by a non-harmful cross-linking agent. The novel continuous nickel plating process additionally saves significant amounts of nickel electrolytes.

Application examples



Cost

At the request of the local bank Effizienz-Agentur (EFA) North Rhine-Westphalia carried out financial consulting prior to the implementation of the project. BIA then applied for funding from the Environment Innovation Programme of the Federal Ministry for the Environment, Nature Protection and nuclear Safety and received a 1.1 million € aid. Upon funding approval, EFA also supported the company compiling reports on expenditure of funds and the final report.
