StockMarketWire.com - Surface coating technology provider Hardide said Wednesday preliminary results showed that its nanostructured chemical vapour deposition coating could extend the life of steam turbine blades.

The tests carried out by the National Physical Laboratory and the University of Manchester assessed the effectiveness of the Hardide coating as protection from water droplet erosion (WDE) and cracking on FV520B last stage turbine blades.

After 90 hours of exposure to WDE, Hardide-A coated 410 stainless steel samples showed almost no discernible damage in the central zone, the company said.

'Water droplet erosion and fatigue are industry-wide pressing issues and we are very pleased with these initial test results which demonstrate the protection that the Hardide CVD coating offers against water droplet and solid particle erosion,' said Dr Zhuk of Hardide Coatings.

'Water droplet erosion damages the surface of steam and gas turbine blades, increasing turbine rotation drag and reducing efficiency. These tests have proven that the Hardide coating can protect the leading and trailing edges of the blades which will increase their service life and maintain optimal turbine efficiency for longer, saving downtime and maintenance costs.'
