The company is supplying stainless metal powder for the laser surface coating to Roussakis SA for the repair of an 11 m long, 26 ton propeller shaft.
Normally, surface coating is not used on critical components in ship repair, but instead, new parts are fitted. Double surface coating using two different Surfit stainless powders from Höganäs enabled an end-result that was harder than the base material, with impact strength three times higher. Because the process was completed with less smelting of the shaft material than in normal welding, there was no negative effect on the actual shaft during the process.
