Making marine components sustainable 28 June 2021

Bodycote Plc, a provider of heat treatments and specialist thermal processing services, is targeting the marine renewables sector after providing its Corr-I-Durr® for key metal components in Wave Energy Converters (WECs) from CorPower Ocean.

The Corr-I-Dur® thermochemical treatment simultaneously improves corrosion resistance and wear properties by generating an iron nitride-oxide compound layer – helping protect against the harshest marine conditions. With durability and robustness being of paramount importance in the wave energy sector, the effective protection of devices in the hostile ocean environment has always presented a major challenge to the industry.

CorPower’s high efficiency WECs, inspired by the pumping principles of the human heart, offer five times more energy per tonne compared to previously known technologies. Incorporating a series of unique features to boost storm survivability and power capture.

“After our initial collaboration we have now worked with Bodycote at a number of plant locations across Sweden to develop mechanical components for our WECs. Corr-I-Dur has proved a particularly favourable solution being specifically designed for components subjected to a corrosive environment in combination with wear,” commented Thomas Lindahl, senior procurement and quality engineer at CorPower Ocean.
