Study on repairing of titanium-stainless steel clad plate by powder feeding laser additive manufacturing process
摘要
Abstract
In order to solve the problem that unexpected defects generated during the manufacturing and service process of titanium steel clad plate cannot be repaired directly by fusion welding,the feasibility of powder feeding laser additive manufacturing technology of TA2/S30408 clad plate was studied by selecting appropriate type and thickness of interlayer.The results show that compared with Cu-Ti gradient deposition layer,the pure copper layer with a smaller crack initiation and propagation tendency during deposition is more suitable as the interlayer of the titanium-stainless steel clad plate;When the total thickness of the pure copper interlayer after multiple deposition is controlled at 1～1.2 mm,the diffusion of Fe element from stainless steel layer to titanium layer can be effectively prevented without reducing interfacial shear strength of the clad plate.TA2/S30408 clad plate exhibits excellent interlayer bonding between each deposition layer,no obvious porosity cracks and other defects,and shear strength reaches the standard.Titanium-stainless steel clad plate is expected to be repaired by powder feeding additive manufacturing process.关键词
