Reclamation of Ship Propeller Shafts

Metallizing Equipment Company (MEC) is a pioneer in thermal spray equipment, materials, and coatings technology. With wide period of experience (more than 45 years) in this field, the company offers solutions for marine industry in terms of equipment and surface related problems. Due to the constant rotation of a ship’s propeller shaft in a harsh marine environment, the bearing areas are very susceptible to wear, consequently giving rise to the inclusion of sand, salt water and other debris, leading to bearing seizure and loss of propulsion. By using the flame spray process (MEC-Sprayjet-88) it is possible to apply a coating of stainless steel (SS-316) on to the worn bearing areas of the propeller shaft bringing them back up to the original size at a fraction of their replacement cost. On manganese bronze type propeller shafts, it has been found that bearing areas reclaimed by applying a layer of flame sprayed Stainless Steel 316 using the same procedure will give up to double the life of original materials and in turn, reducing the total maintenance costs.
