Research on In-situ Repair Process of Flanges for a Certain Type of Shipborne Equipment
In view of the serious corrosion,volume damage and loss of water tightness issues for failure of a certain flange of ship equipment,an in-situ repairing plan was designed and applied,which was mainly based on laser cladding and assisted by pulse surfacing process.The multi-component high-entropy alloy was selected as the repairing material,which laser repairing of straight edges of flange with volume damage,and overlay welding repairing of corners edges of the flange.After repairing engineering,the original size,morphology and water tightness of flange convex were restored.Moreover,the cladding layer presented a typical rapid solidification dendritic structure,exhibited good metallurgical bonding with the substrate of Q345 materials,and had better corrosion resistance,high temperature oxidation resistance and mechanical properties.
